ZONESENTINEL
®
AC Panel Transient Voltage Surge Suppressors
INTRODUCTION
This document explains how to install the Powerware TVSS ZoneSentinel® AC Panel Surge
Protection Devices.
INSTALLATION INSTRUCTIONS
Warning: Terminals marked L1, L2, L3, N, GND (where relevant) must be connected
respectively to phase(s) neutral and ground. Failure to comply may result in danger or
damage. See corresponding diagrams for proper connections.
INSTALLATION DESCRIPTION
Powerware TVSS ZoneSentinel® units are connected in parallel (or in "shunt" across) the
supply to be protected. The connecting cable does not carry the supply current, only the current
associated with suppressing the transient overvoltage.
MOUNTING
The units should be mounted as close as possible to the panel to be protected. See Connecting Lead lengths on page 5. Conduit, preferably metallic, is to be installed from the suppressor to the panel. Drill holes in the Powerware TVSS ZoneSentinel® enclosure only in the
designated areas as shown in recommended cable dressing illustrations (page 6). Mount the
unit in the appropriate location using the mounting holes provided on the enclosure.

FLUSH MOUNT
The flush mount Powerware TVSS ZoneSentinel® is installed into a suitably sized hole in the
wall. Remove the four snap-in screw covers and remove the cover, temporarily disconnect the
cover ground wire. Choose a location such that the
recessed part of the Powerware TVSS
®
ZoneSentinel
enclosure can be fixed to a wall stud or suitable upper or lower support. Be
sure that the Powerware TVSS ZoneSentinel® enclosure is flush with the wall. Follow the
standard instructions for location and connecting leads. Reconnect the cover ground wire and
install the cover plate. Replace the four snap-in screw covers.
INCORRECT INSTALLATION WILL IMPAIR THE EFFECTIVENESS OF THE AC
PANEL PROTECTORS. Particularly important is the length of the connecting leads (page 5).

REMOTE INDICATORS
A remote indication of the reduced protection state is available as a normally open or normally
closed dry contact. Pluggable connectors must be wired as shown below.

WARNING: OF HIGH NEUTRAL TO GROUND VOLTAGE
On certain models, a RED warning light is provided. Should this light glow RED at any time, consult
a qualified electrical contractor to check the integrity of the building wiring. This RED light does
not indicate suppressor failure, however a RED glowing light is indicative of potentially hazardous
site wiring.

CONNECTING LEADS
Connect the suppressor as shown in the installation diagram. Refer to page 5 for
recommended cable dressing. Connect the terminals within the suppressor to the
load side of 30A breakers within the panel.
RECOMMENDED WIRE GAUGE
Minimum of 10 AWG
Maximum of 4 AWG ( for ease of dressing)
LENGTH OF CONNECTING LEADS
The longer the connecting leads between the the ZoneSentinel and power panel, the
higher the residual transient voltage.
RECOMMENDED MAXIMUM:
IDEALLY :
500mm (19")
250mm (10")
Each 250mm increase in cable length; increases clamping voltage by 25V per 1000A
surge current discharged.
• BIND THE PHASE NEUTRAL AND GROUND CONDUCTORS TIGHTLY
OVER THE ENTIRE RUN FROM THE SUPPRESSOR TO THE SERVICE
PANEL.
• ALWAYS USE THE SHORTEST LENGTH OF CONNECTING CABLE
POSSIBLE.

MAINTENANCE
At intervals not exceeding two months, check:
1. Status indication lights
2. Conditions of connecting cables and terminals
Module Replacement
WARNING: Before opening the access panel, ensure that the AC supply has been
disconnected.
Unplug the remote contact connector at the top of the module. Remove the mounting nuts
at the top and bottom of the module. The protection module can now be removed.
WARNING: Replace the defective module with a module having the same model
numbers.
Installation of the replacement module is the reverse of the above procedure. Final step,
check that all cable connections are secure and nuts are tightened. Do not overtighten.
NOTE: No customer serviceable parts inside. Opening module WILL void
