UNPACKING AND INSTALLATION
Unpacking and Preliminary Inspection
EQUIPMENT PERFORMANCE!!
1. Inspect the shipping crate(s) for damage or signs of
mishandling before unpacking the unit.
To maximize system performance locate unit as
close as possible to protected circuit and keep inter-
connecting wiring less than 5 ft.
2. Remove any securing bands and cardboard packing and
inspect the unit for any obvious shipping damages.
3. Ifanydamageasaresultofshippingisobserved,immediately
file a claim with the shipping agency and forward a copy to
your local Liebert Sales Representative.
For optimum transient surge protection, coordinated surge
suppression should be applied at the service entrance and all
other electrical connections to the building (telephone, CATV,
etc.), at known surge generating loads within the building
(large motors, arc welders, switched capacitors, etc.), as well
as at sensitive electronic loads (such as computers, electronic
appliances, solid state motor drives, etc.). For interconnected
electronicloads(suchasbywayofdatacabling),transientsurge
suppression should also be applied to the interconnecting
wiring (data cables).
Handling Considerations
Larger units are bolted to a shipping pallet to facilitate handling
by forklift or pallet jack. Check the size and weight. Refer to
the cabinet data furnished with the unit.

Surge Suppression Systems
ELECTRICAL CONNECTIONS
All electrical connections should be installed by a qualified
(licensed) electrician only. All wiring must comply with the
National Electrical Code (NEC) and applicable local codes.
The following is from the National Electric Code 2002 Edition.
285.21 Connection. Where a TVSS is installed, it shall be
connected as follows:
(A) Location.
(1) Service Supplied Building or Structure. The transient
voltage surge suppressor shall be connected on the
load side of a service disconnect overcurrent device
required in 230.91.
VERIFY THAT ALL POWER CIRCUITS ARE
DE-ENERGIZED AND LOCKED OUT BEFORE
MAKING ELECTRICAL CONNECTIONS.
(2) Feeder Supplied Building or Structure. The transient
voltage surge suppressor shall be connected on the
load side of the first overcurrent device at the building
or structure.
Voltage Ratings and Power Source Configurations
Exception to (1) and (2): Where the TVSS is also listed as a surge
arrestor, the connection shall be as permitted by Article 280.
Before making connections to the unit, verify that the unit
model number and nameplate voltage rating are appropriate
for connection to the intended power source. See the chart
on page 4 for voltage rating applications with typical power
source configurations.
(3) Separately Derived System. The TVSS shall be
connected on the load side of the first overcurrent
device in a separately derived system.
Disconnect Switch (If Provided) — All SPD units must still be
connected to the load side of the main service disconnect, or
load side of a protected circuit’s disconnecting means.
Parallel Connection (see Figures on page 5)
EQUIPMENT PERFORMANCE!!
Surge Voltage Ratings — To obtain the suppression voltage
ratings (SVRs), as obtained by Underwriters Laboratory,
Incorporated, in accordance with the Standard for Safety,
Transient Voltage Surge Suppressors (TVSS), Standard 1449,
Second Edition, dated August 15, 1996, marked on this
product, the wire size listed for each product must be utilized
to connect the unit to your facilities’ power grid. Connections
made with conductors other than the wire size listed may
result in different SVRs.
For maximum system performance, the unit must be
located as close to the protected circuit as practical
to minimize interconnecting wiring length.
To reduce the wiring impedance to surge currents, it is
recommended that the phase, neutral (if required), and ground
conductors are twisted together and routed in the same
raceway (conduit). Avoid any sharp bends in the conductors.
Wire Sizing — With parallel connection, the size of the
wiring to the SPD unit is independent of the protected
circuit’s ampacity. For suggested wire size refer to individual
product sheet.
Circuit Ampacity Limitations
—
Representative samples
of these products have been investigated by Underwriters
Laboratories, Incorporated to withstand, without exposing
live circuits or components at system voltages and fault
currents ranging from 14,000 AIC up to 200,000 AIC, as
described in the Standard for Safety, Transient Voltage Surge
Suppressor (TVSS), Standard 1449, Second Edition, dated
August 15, 1996. Verify each products fault current rating on
the individual installation pages that follow.
NEC Article 285-21(B) requires surge suppressor connecting
conductors to be at least #14 copper or #12 aluminum.
Overcurrent Protection — The SPD unit conducts practically
no current under normal operation and only conducts very
short duration transient surge currents.

Surge Suppression Systems
System Grounding and Bonding
The performance and safety of any SPD system is dependent
on proper grounding and bonding. Grounding is required for
safety. Correct implementation also enhances equipment
performance. Incorrect grounding can reduce or impede the
SPD’s operation.
FOR PROPER AND SAFE OPERATION, THE NEUTRAL, (IF
PROVIDED), MUST BE RELIABLY CONNECTED TO THE
NEUTRAL OF THE SOURCE. FAILURE TO PROVIDE A RELIABLE
NEUTRAL CONNECTION MAY RESULT IN MODULE FAILURE!
All electrical circuits to the SPD must include an equipment-
grounding conductor as required by the NEC and local codes.
SPD Monitoring
External Status Indicators — These indicators provide a
summary of the status of the surge SPD module. For normal
conditions, the green “OK” LED is illuminated and the red
“Service” LED is extinguished. If the surge SPD module
requires replacement, the green “OK” LED is turned off and
the red “Service” LED illuminated.
An insulated grounding conductor is required in addition to any
metallicraceway, whichmaybeusedasagroundingconductor.
For parallel-connected SPDs, the grounding conductor should
be the same wire size as the associated power conductors.
Grounding conductors must be routed with the associated
power conductors in the same raceway (conduit).
Summary Alarm Contact (if applicable) — Summary alarm
Form C (1 N.O. and 1 N.C.) relay contacts may be provided for
remote indication of the failed surge SPD module.
When metallic raceways are used, adequate electrical
continuity must be maintained at all raceway connections,
particularly raceway terminations to the electrical enclosures.
Contacts are rated 5 amps at 250 VAC maximum with a power
factor of 1.0. For units with Summary Alarm Contacts, access
to the contacts are typically provided via contact terminals
located on the printed circuit board mounted on the inside of
the unit’s cover.
The use of isolating bushings or other means to interrupt a
metallic conduit run is a potential safety hazard and is not
recommended.
Grounding Electrode — Surge protective devices do not
discharge all surges to ground (earth). Surge protective
devices divert the surge current back to its source to complete
the electrical circuit.
Transient Counter (if applicable) – Transient counters are
provided for transient voltage surge monitoring. The counter
totalizes surges monitored since the last counter reset.
In the case of lightning whose potential is developed with
respect to the earth, the SPD diverts the surge current to
the grounding electrode (earth connection). However, for
most transient surges that are developed by switching loads,
the SPD diverts the surge current back to its source without
involving the grounding electrode.
The transient counter monitors line transient voltages. The
circuit counts all surges that deviate from the line sine wave.
The factory setting is 30% over nominal line voltage. Other
settings include 50%, 70%, and 100%.
Swell Counter (if applicable) — The swell counter monitors
line to line & line to neutral voltages. It is factory set to record
whenever the peak voltage on any normal mode exceeds the
nominal voltage of the TVSS for more than 10ms. This counter
records temporary line over voltages that may result from
utility switching, line regulation problems, etc.
For proper SPD performance, the service entrance grounding
electrode system must comply with the NEC by having all
available electrodes (building steel, metal water pipe, driven
rods, concrete encased electrodes, etc.) properly bonded
together and connected to the power system grounding.
Audible Alarm (if applicable) — If the surge SPD module
requires replacement, an audible alarm is activated to draw
attention to the fact that repair service is required to restore
the system to normal operation. An audible alarm disable is
provided to silence the alarm. The system will automatically
reset itself after repair. The audible alarm switch and “Service”
LED can be tested by activating the “Test” switch on the
system monitor panel. For information on the AccuVar Series
Alarm, see page 16.
The use of a separate grounding electrode to ground the SPD

National Electrical Code (NEC) Considerations
The National Electrical Code Article 240-21 details specific tap rules that should be considered before installation.
NEC 240.21 Location in Circuit. Over current protection shall be provided in each ungrounded circuit conductor and shall
be located at the point where the conductors receive their supply except as specified in 240.21(A) through (G). No conductor
supplied under the provisions of 240.21(A) through (G) shall supply another conductor under those provisions, except through
an over current protective device meeting the requirements of 240.4.
(A) Branch-Circuit Conductors. Branch-circuit tap conductors meeting the requirements specified in 210.19 shall be
permitted to have over current protection located as specified in that section.
(B) Feeder Taps. Conductors shall be permitted to be tapped, without over current protection at the tap, to a feeder as
specified in 240.21(B)(1) through (5).
(1) Taps Not Over 3 m (10 ft) Long. Where the length of the tap conductors does not exceed 3 m (10 ft) and the tap
conductors comply with all of the following:
(1) The Ampacity of the tap conductors (25 Amps in our case) is
a. Not less than the combined computed loads on the circuits supplied by the tap conductors, and
b. Not less than the rating of the device supplied by the tap conductors or not less than the rating of the over
current protective device at the termination of the tap conductors.
(2) The tap conductors do not extend beyond the switchboard, panelboard, disconnecting means, or control devices
they supply.
(3) Except at the point of connection to the feeder, the tap conductors are enclosed in a raceway, which shall extend
from the tap to the enclosure of an enclosed switchboard, panelboard, or control devices, or to the back of an
open switchboard.
(4) For field installations where the tap conductors leave the enclosure or vault in which the tap is made, the rating
of the over current device on the line side of the tap conductors shall not exceed 10 times the Ampacity of the
tap conductor.
(2) Taps Not Over 7.5 m (25 ft) Long. Where the length of the tap conductors does not exceed 7.5 m (25 ft) and the tap
conductors comply with all of the following:
(1) The Ampacity of the tap conductors is not less than one-third of the rating of the over current device protecting the
feeder conductors (75 Amp maximum in our case).
(2) The tap conductors terminate in a single circuit breaker or a single set of fuses that will limit the load to the
Ampacity of the tap conductors. This device shall be permitted to supply any number of additional over current
devices on its load side.
(3) The tap conductors are suitably protected from physical damage or are enclosed in a raceway.
(3) Taps Supplying a Transformer. Not Applicable
(4) Taps Over 7.5 m (25 ft) Long. Not Applicable
(5) Outside Taps of Unlimited Length. Not Applicable
Flexible liquid tight non-metallic conduit in lengths greater than six feet must be installed in accordance with NEC 351-27.

Equipment Performance
The ideal SPD installation locates the suppression as close to the protected bus as possible. This product was designed to address
those instances when a close installation is not possible. However, while the voltage drop experienced with an AccuGuide
assembly is significantly reduced, care should be taken to keep connection lengths to a minimum.
Each end of the AccuGuide assembly is shipped with five-foot pigtails. The length is offered as a worst-case need for the panel or
switchgear end (our SPD will be much less than 5 feet). We recommend cutting the pigtail to the shortest length possible.
Caution: Pigtails must be supported if pulling AccuGuide assembly through conduit. Grip only the blue coaxial cable
body when pulling the assembly through conduit. Do not pull AccuGuide assembly using the pigtails or damage
may occur.
