IMPORTANT SAFETY INSTRUCTIONS  
IMPORTANT SAFETY INSTRUCTIONS  
Important Notice  
The UPS has its own internal energy source (battery). Should the battery be switched on when  
no AC power is available, there could be voltage at the output sockets.  
Make sure that the AC Utility outlet is correctly grounded.  
Do not open the case, as there are no serviceable parts inside. Your warranty will be void.  
Please make sure that the input voltage of the UPS matches the supply voltage.  
To eliminate any overheating of the UPS, keep all ventilation openings free from obstruction,  
and do not store "things" on top of the UPS. Keep the UPS 30cm away from the wall.  
Make sure the UPS is installed within the proper environment as specified (0-40° C and 30-  
90% non-condensing humidity).  
Do install the UPS in direct sunlight.  
Install the UPS indoors as it is not designed for installation outdoors.  
Dusty, corrosive and salty environments can do damage to any UPS.  
Install the UPS away from objects that give off excessive heat and areas that are excessively  
wet.  
The battery will discharge naturally if the system is unused for any length of time.  
It should be recharged every 2-3 months if unused. When installed and being used, the  
batteries will be automatically recharged and kept in top condition.  
Do not install the UPS in an environment with sparks, smoke or gas.  
Make sure the UPS is completely turned off when moving the UPS from one place to another.  
It might cause electrical shock if the output is not cut completely.  
Storage Instructions  
For extended storage through moderate climate, the batteries should be charged for 12 hours every 3  
months by plugging the UPS power cord into the wall receptacle and turn on input breaker on front  
panel.  
Repeat this procedure every 2 months under high temperature environment.

Assembling the Battery Pack  
Assembling the Battery Pack  
Overview  
The UPS battery needs to be assembled before installation: the battery pack consists of four individual  
batteries, a connector wiring package (one large wire harness with two black and two red wires attached  
to a four-pin connector and two separate red wires), and the aluminum battery case components.  
Each battery has color-coded contacts, with red for "positive" and black for "negative". Each battery will  
lie on its side in the battery case, as part of a pair, with the contacts of one at the opposite end as the  
contacts of the other. The completed battery case will not slide into the unit when wired if the batteries  
are not in this position when the case is assembled. (See FIG. 6).  
FIG. 3 Connecting the batteries to each other and to the 4-pin connector  
1. Remove the batteries from their packing material and stand them upright on the bottom of the  
battery case, making two pairs. Alternate the batteries so the contacts of one in each pair are  
opposite the contacts of the other. (See FIG. 3)  
2. With the contacts facing up, take the large wire harness (the one with the yellow 4-pin connector at  
one end) and connect each pair to the assembly. Make sure that the color of each wire, red or black,  
matches the color of the battery contact. Only attach one wire from the harness to each battery.  
When attaching the wire harness to the battery pairs, note the red-black wire pairs  
coming from the connector. The black and red wires in each set emerging from the  
connector must be attached to its matching contact in only one battery pair;  
connecting a red wire to one battery pair and a black wire to the other battery pair will  
not complete the circuit and the battery pack will not work.  
3. The remaining two wires from the wiring package complete the serial circuit. Connect the red wire  
first to a red contact on one battery and then to a black contact on the other in the pair. Likewise,  
connect the black wire first to the remaining black contact, then to the remaining red contact in the  
second pair.  
4. At this point, flip the batteries so that their wide and long sides face down. Make sure that the  
contacts of each battery face the side containing contacts on the other in its pair. Gently put tension  
on the wires to take up any slack; the wire harness should be hanging to one side. The wires  
themselves should run between the battery pairs until they emerge from the side. If any wire should  
hang over the top of the batteries, gently press it down between the batteries to keep it out of the  
way.  
5. Assemble the battery case around the battery pairs. When installing the battery in the unit, the wire  
assembly will hang out from the right side of the battery pack.

Connecting the UPS  
Connect Network Surge Protection  
Connect a 10Base-T/100 Base-T network cable to the RJ45 network surge protection "IN" jack on the  
rear of the UPS. Connect from the "OUT" jack with network equipment (FIG. 18).  
FIG. 18 Connect Network Surge Protection  
If using the NXA-UPS1500 as part of a MAX system, do not run the A/V segment of  
the network through the RJ45 network surge protection jack on the UPS. The A/V  
segment of a MAX network requires a GB Ethernet switch, and the NXA-UPS1500  
only provides a 10/100 connection. You can connect the Control segment of the MAX  
network to the UPS, since it does not require a GB connection to operate properly.  
Connect the RS-232 Communication Port  
Connect the supplied RS-232 interface cable between the RS-232 port on the rear of the UPS and an  
available RS-232 port on the NetLinx Master (FIG. 19).

Overview  
1. When the Battery Replacement LED (Red) lights up, you may leave the UPS to be re-charged for at  
least 8~10 hours to see whether the Red LED will be extinguished after the Self-Test function is  
executed again.  
2. In case the Red LED remains unchanged, you may unscrew the Hot Swappable Battery cover to  
replace a new battery, then press the “On” Switch to disable the Red LED.  
Once the battery is disconnected, the loads are not protected from power outages.
