100 Introduction
This manual explains how to start your FERRUPS, interpret its status lights, use its display and communication
features, and get assistance if you have a FERRUPS problem. This manual also includes specifications and
warranty information. If your FERRUPS is not a soft-wired (plug-in) model, your electrician should install the
FERRUPS using the Installation Manual included with your unit. If your UPS has one or more separate battery
cabinets, you should also use the instructions in the Installation Manual to connect the cabinet(s) to the
FERRUPS.
To find information in this manual, use the contents above.
Best Power is committed to outstanding customer service. If you have a problem or question, our Worldwide
Service center is happy to help you. Simply refer to the list of Best Power offices at the beginning of this manual

300 Starting the UPS
Note: If you plan to store your UPS, the storage temperature must be between –20° and +40° Celsius (–4° and
+104° Fahrenheit). If the UPS does not have internal batteries, you can store it at –20° to +60° C (–4° to
+140° F). The batteries must be recharged every 90-120 days. To recharge the batteries, start the
UPS and let it operate for 8 hours. (If the batteries are in a separate cabinet, make sure the
cabinet is connected to the UPS.)
Before you start the UPS, make sure the temperature is 0° to 40° Celsius (32° to 104° Fahrenheit). The relative
humidity must be 0-95% without condensation. The air must be free of dust, chemicals that corrode, or other
contaminants, and it must be free to move around the UPS.
CAUTION
To avoid possible equipment damage or personal injury, assume that the FERRUPS terminals or receptacles
(outlets) may have AC voltage present whenever AC input voltage or DC battery voltage is supplied.
FERRUPS can provide output voltage from its batteries even when there is no AC input voltage. When AC
input voltage is available, FERRUPS can provide output voltage even when its batteries are disconnected. To
make sure there will be no UPS output voltage, always disconnect the AC input source; if you have a separate
battery cabinet, you must also shut off the DC switch or disconnect the battery cabinet from the UPS.
To reduce the risk of electric shock, install the UPS in a temperature-controlled indoor area free of conductive
contaminants.
When the UPS is shipped, two sections of the front panel are not attached. Attach the front panel
sections before starting the UPS.
When you receive the FERRUPS, two sections of the front panel
1
2
are not attached. You will find the panel sections in the packing
material on the top of the UPS.
Attach the smaller of the two panels to the middle section. To do
this, fit the slots on the back of the panel over the metal tabs on the
front of the UPS. Then, push the panel in until it snaps in place.
Make sure the panel is completely attached with no gaps between
the panel and the UPS. Attach the larger of the two panels to the
bottom section of the UPS.
If your UPS is not a soft-wired (plug-in) model, an electrician must install the UPS and connect the
equipment you want to protect. See the FERRUPS Installation Manual. After the UPS has been installed,
If your UPS is a soft-wired (plug-in) model, turn off the equipment you want to protect.

Models with permanently attached power cords (shown):
Plug in the UPS. If the plug on the UPS’ power cord does not
match your outlet (receptacle), an electrician must install the
proper outlet.
3
Models with power cords that must be plugged in:
Do not use the cord that came with your UPS to plug it in; this
cord is for connecting your equipment to the UPS. Your computer,
or the equipment that you want to protect, should have a power
cord that you can unplug or disconnect. Disconnect this cord from
your equipment, connect the cord to the back of your UPS, and
use it to plug in the UPS. Once you have plugged in the UPS, the
green light on the front panel should be on. (If you need to order a
UPS power cord, call the nearest Best Power office.)
If your FERRUPS has one or more separate battery cabinets, the battery
packs should already be installed. (See the Installation Manual.) Find
the red DC switch on the back of each battery cabinet. Insert the key into
the DC switch and turn it all the way to the right (clockwise); then, pull
the switch out to turn the DC on. When you want to turn the switch off,
simply push it in — you do not need the key to turn DC off.

On
At the UPS back panel, press and hold the On/Off switch until the unit
starts. AC input power must be present for the FERRUPS to start.
When the unit starts, it runs on battery power briefly; then, the green
light on the FERRUPS front panel will be on to show the unit is
running on AC line input. Whenever the yellow light is on, the unit is
running on battery power because of a power outage or power problem.
When the green light is on, the display will show the following:

FERRUPS automatically charges the batteries
whenever AC input power is available. If this is the first time
you’ve started the FERRUPS, let it charge the batteries for 8 hours
before you go on. You can use the UPS right away, but its battery
backup time (runtime) will be shorter until the batteries are fully charged.
LINE
If your unit has a bypass switch, check for a red button next to the switch
(shown). If the bypass switch has a red button, press it, then turn the switch
to “UPS.” If not, simply turn the switch to “UPS.”

“UPS”
FERRUPS comes with a CheckUPS software package that
lets you connect the FERRUPS to your computer and
monitor UPS operation and power conditions. During longer
power outages, CheckUPS also can shut down your computer
automatically before the UPS runs out of battery backup time.
To start using CheckUPS, find the interface cable packed
with your CheckUPS software. Connect the “UPS” end of
this cable to the FERRUPS’ port, and connect the other end
of the cable to your computer.
To your
computer
To install the CheckUPS software, see the instructions in the CheckUPS CD case.
The FERRUPS is now providing continuous, computer-grade power to your equipment. It is ready to
provide battery backup power when needed. Please fill out the warranty registration card in this manual
and return it to Best Power within ten days of installation.

Light
The red Alarm light means the UPS has detected a problem. When this happens, the display shows an alarm
The yellow Battery light means the UPS is operating on battery power, either because there is a power outage
or because the available AC input power is not usable. When this happens, the display shows “On Battery,” the
runtime, and the battery voltage. (You can press the bottom right buttton to switch to the menu display; see
Section 501.) The UPS will continue to run on battery power until the power problem ends or the UPS’ batteries
discharge. If the batteries discharge, the UPS will sound alarms shortly before shutting down.
The green AC Line light means the UPS is using the available AC input power. The UPS conditions the power
before providing output to your equipment. While the FERRUPS is using AC input power, it displays “System
Mode Auto” and whether the battery charger is on or off. You can press the bottom right button to switch to the
500 Using the Display
This section explains how you can use the FERRUPS’ front panel display to get more information about
FERRUPS operation or to change settings. You can use the display to enter a password, display and change
system settings (parameters), and display system logs.
501 Displaying and Moving through the Menus
The FERRUPS display groups information in 7 different menus. See the Menu Map on page 11; the items
numbered 1-7 in the left column of this diagram are the top-level menus. For example, 2 System Status is the
System Status menu. To the right of this menu in the Menu Map, you will notice a list of items that are part of
this menu. Some menus, like menu 5, System Config, have submenus (Gen Sensitivity; Sys Test, Inv, Chg;
System Mode Control; Alarm and Shutdown; and Calibration Factors). Others simply have lists of items directly
below the top level menu.
When you start the UPS, the display shows “Best
Power,” the mode, and whether the charger is on or off.
To change to the menu display, press the bottom right

t
ESC
button (below the word “Menu” on the bottom line of
the display). The display will show the top level in the
first menu (1, Enter password) as shown in the
drawing. Ten minutes after you last press a button, the
display will switch out of menu mode and show the
normal display (see Section 400).

To scroll down through menus or menu items in the same level:
Press the t button on the right side of the display.
To scroll up through menus or menu items in the same level:
Press the s button. You can also look at the bottom line of the display, which includes the words “Top”
and “ESC.” The button under the word “Top” will take you to the top of the list of items in the menu
level.
Example: When you switch to the menu display, the display shows the top item in the top level (1,
Enter password). To scroll down to menu 2 (System Status), press the t button. Press this
button again to scroll down to menu 3 (System Status Info), and so forth. To scroll back up to
menu 1, press s twice or press the button below “Top.”
To display the items in a menu or submenu:
Go to the display that represents the menu or submenu, and press the ¿ button.
Example: The interface starts at the top item in the top level (1, Enter password). If you scroll down to
menu 2, the display shows “System Status.” To display the items in the System Status menu,
press ¿. You can then scroll down and back up through the items in this menu.
To move back up a menu level:
Notice that the bottom line of the display shows “Top” and “ESC.” If you press the button under “ESC”
(the right button below the display), the display goes back to the next higher menu level.
502 Displaying a Parameter by Entering the Parameter Number
For service purposes, parameters are also assigned sequential numbers (1-337). If you know a parameter number
and want to go directly to that parameter, you can use menu 7 in the top level menus (Parameters) to display the
parameter. Simply follow these steps:
1. Scroll down to menu 7, and press ¿. The third line of the display will change to “parameter = 000,” and the
bottom line of the display will change to “<– –> ESC” to show the functions of the three buttons below
the display.
7

parameter # 000
<–
–>
ESC
2. Use the <– and –> buttons to scroll through the digits to the left and right, and use the s and t buttons to
increase or decrease the value of each digit. When the three digits show the number of the parameter you wish
to display, press ¿.
Example: To display parameter 32, you need to change the three digits (000) to “032.” Since you do not
need to change the first digit, press the button below –> to move the cursor to the second digit.
Then, press s three times to increase the second digit to “3.” Next, move to the third digit, and
press s twice to increase this digit to “2.” Now, the display shows “parameter = 032.” Press ¿.
The parameter’s short name and value will appear on the third line of the display.

503 Entering a Password
Before you can change the setting of some FERRUPS parameters or menu items, you must enter a password. To
do this, follow the steps below. The User password is 0377.
1. If the display is not already showing the menus, press the bottom right button (below the word “Menu” on the
bottom line of the display). Go to the top item in the top menu level, “Enter Password.” (If you are not sure
2. Press ¿. The display will show the following:
1 1
Enter Password
0000
<–
–>
ESC
A cursor will appear in the “0000” line of the display.
3. The bottom line of the display will show you which buttons to use to move through the password’s digits
(0000) to the left (<–) and to the right (–>). Move the cursor to the first digit you want to change, and use the
s and t buttons to increase or decrease the number. Repeat this step for each digit that needs to be changed.
4. When the number matches the password you want to enter, press ¿. The password name (such as “User”) will
appear in the upper right corner of the display to remind you which password has been entered. If you begin
entering a password and decide not to enter it, press the bottom right button on the display (the button under
“ESC” for escape).
Example: To enter the User password (377), use the button below “–>” to move to the second digit in
“0000”; then, press the s button three times to increase this digit to “3.” Next, press –> to move
to the third digit, and press s seven times to increase this digit to “7.” Then, press –> again to
move to the last digit, and press s seven times to increase this digit to “7.” The display should
now show “0377.” This is the User password. Press ¿. “User” will appear in the upper right
corner of the display to show you the User password has been entered.
504 Changing a Parameter Setting
Some of the items that you can view on the front panel display can be programmed (such as the time, date, and

2. Press ¿. If you can change the item without a password (or with the password you have already entered), a
cursor will appear in the value that you can change. The bottom line of the display will change to
“<– –> ESC”. Use the buttons below “<–” and “–>” to move the cursor to the left and right, and use the
button below “ESC” to escape and discard any changes you have made. See the drawing on the next page,
which shows what the display would look like if you were changing the time.

506 Reading the FERRUPS Logs
Your FERRUPS makes an entry in its logs every time it sounds an alarm or runs on inverter (battery
power). This information can help diagnose power problems. You can display both the Alarm and Inverter
logs at the unit’s display panel; both logs are in menu 6.
Inverter Log
The Inverter Log is in menu 6, submenu 2. To display the log, follow these steps:
1. Press the bottom right button (below “Menu” on the display) to switch from the normal display to
the menus. The display will show the top menu, “1 Enter Password.”
2. Press t five times (until the display shows “6 System Logs”).
3. Press ¿. The display will show “6 1 Data Log.”
4. Press t once. The display will show “6 2 Inverter Log.”
5. Press ¿. The display will show the first entry in the inverter log.
The log stores up to 16 entries. You can use the s and t buttons to scroll up and down through the log
entries. Each entry shows the inverter code, then the date the unit ran on inverter, the time it ran on inverter
(in 24-hour time), and the duration (in hours, minutes, and seconds.) For example, one entry might look like
this:
l 0205 0951 001505
In this example, “l” means the FERRUPS went to battery power because it lost AC input power. (See
the table on the next page.) If the unit was still running on inverter (battery power), there would be an
asterisk (*) after the “l.” “0205” means the date of the battery power operation was February 5 (2/5).
“0951” means the inverter ran at 9:51 a.m. “001505” means the inverter ran for 0 hours, 15 minutes,
and 5 seconds.

700 Communication
701 Communication Options
Best Power offers several methods of communicating with your FERRUPS:
CheckUPS Software: Each FERRUPS unit ships with CheckUPS power monitoring and unattended
shutdown software. To begin installing CheckUPS, see the instructions in the
CheckUPS CD case.
CheckUPS uses an RS-232 serial link to communicate with the FERRUPS, and it
provides you with up-to-date graphics of UPS power and system data and power
flow. CheckUPS also gives you a complete record of critical power events, and it
notifies you of important UPS or power information. If there is a power outage and
the FERRUPS battery power becomes low, CheckUPS can automatically shut down
your computer system before the UPS Low Battery shutdown to protect your data.
RS232
Communication:
You can connect a terminal or a computer with terminal emulation software to the
FERRUPS’ communication port. This allows you to receive information from the
FERRUPS or send commands in order to display and program parameters. For more
information, call the nearest Best Power office.
19
Download from Www.Somanuals.com. All Manuals Search And Download.
Optional Interface Kits:
For computer systems that already have UPS monitoring software, Best
Power offers interface cable kits for connecting the FERRUPS to your
computer system. The kit includes the cable, adapters, and instructions.
Optional Internal Bestlink™
SNMP/Web Adapter:
Using Simple Network Management Protocol (SNMP), system
administrators can easily monitor and manage remote UPS units that protect
key network devices like servers, routers, and hubs. Best Power’s SNMP
Adapters provide a self-contained link between the FERRUPS and an
Ethernet or Token Ring LAN/WAN. The adapters allow the system
administrator to communicate with the FERRUPS even after the protected
device goes down. The SNMP adapter displays over 60 Management
Information Base (MIB) variables to give the system administrator
information about UPS operation.
BestDock™
FERRUPS has a communication slot that allows quick installation of an optional
SNMP card.
Emergency Power
Off (EPO):
You can connect your FERRUPS to your Emergency Shutdown switch to provide a
method for emergency FERRUPS shutdown. This connection shuts down the
FERRUPS output. See the Installation Manual to make the connection.
702 DB9 Port Pin Functions
The table below explains the functions of the pins on the FERRUPS’ DB9 port. This port is on the
FERRUPS’ back panel. The functions of pins 1 and 2 change depending on the communication mode.
When you receive the UPS, it is set up for RS232 mode. However, if you want to use the alternate
functions of pins 1 and 2, you can change the mode by following the steps on the next page.
Pin Function
1
In RS232 mode, this pin receives incoming RS232 communication data.
In Extended Contact Mode, this pin can cause a remote shutdown. If the UPS is using battery power and a
+12-volt DC signal is applied to this pin for 5 seconds, the UPS will shut down 20 seconds later. When the
power outage ends, the UPS will automatically restart after 15 seconds. Signal and shutdown times and
automatic restart are programmable; for more information, call the nearest Best Power office.

800 Maintenance and Service
801 Regular Maintenance
Best Power designed your FERRUPS to provide years of trouble-free operation. Its microprocessor will
check the batteries and inverter at programmable intervals to ensure proper operation. In fact, you’ll
probably find that your FERRUPS requires less maintenance than any of your other computer peripherals.
Nevertheless, your FERRUPS does require some attention in order to provide you with excellent service.
Best Power recommends that you schedule a Preventative Maintenance check at least every six months. At
this check, the service technician should follow Best Power’s Recommended Maintenance Schedule, which
includes the following:
• Inspect and clean the unit.
• Inspect and record the alarm and inverter logs.
• Check the batteries.
• Check the AC and DC meter functions and recalibrate if necessary.
• Perform a system test.
• Check and record the values of the parameters in menu 3 on line and on inverter.
The technician must observe important safety precautions while performing these checks. For more
information on what your technician should do in a Preventative Maintenance check, or to schedule Preventative
Maintenance with a Best Power-authorized field service representative, call Best Power’s Worldwide Service.
We’ll be happy to help you.
