& User Manual
Powerware TVSS

MOUNTING
The units should be mounted as close as possible to the panel to be protected. See (page 4) on
Connecting Lead lengths. Conduit, preferably metallic, is to be installed from the suppressor to the
panel. Drill holes in the Powerware TVSS ZoneMaster PLUS®enclosure only in the designated areas
as shown in recommended cable dressing illustrations (page 5). Mount the unit in the appropriate
location using the mounting holes provided on the enclosure.
INCORRECT INSTALLATION WILL IMPAIR THE EFFECTIVENESS OF THE
AC PANEL PROTECTORS.
Particularly important is the length of the connecting leads (see pages 4 & 5).
INTRODUCTION
This document explains how to install the Powerware TVSS ZoneMaster PLUS®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 ZoneMaster PLUS®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.

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 poten-
tially hazardous site wiring.

STATUS INDICATORS
The Powerware TVSS ZoneMaster® PLUS units have comprehensive, continuous visual
status monitoring present on each module.
REMOTE INDICATORS
A remote indication of the reduced protection state is available as a
normally open or normally closed dry contact.

CONNECTING LEADS
Connect the suppressor as shown in the installation diagram. Refer to page 5 for recommended
cable dressing. The recommended installation is to connect the terminals within the suppressor to
the load side of 60A breakers or fuses within the panel. See specific connection diagrams for more
details and markings on unit if provided.
RECOMMENDED WIRE GAUGE
Minimum of 8 AWG
Maximum of 4 AWG ( for ease of dressing)
LENGTH OF CONNECTING LEADS
The longer the connecting leads between the the ZoneMaster® PLUS and power panel, the
higher the residual transient voltage.
RECOMMENDED MAXIMUM:500mm (19")
IDEALLY: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.

INSTALLATION/OPERATING INSTRUCTIONS
1. Disconnect power to ZoneMaster PLUS®by pulling on disconnect.
2. Attach the black and white pair wire across the surge module by removing the screws and attaching
the lugs from the counter. The white wire connects to the left side of the module and the black wire
connects to the right side of the module.
3. The neutral or ground wire connected to the ZoneMaster PLUS®should be removed and
inserted through the toroid from the counter and reinstalled to the ZoneMaster PLUS®wire lug.
Note: If it is desired to measure surge currents on only a single individual phase, insert selected
phase connection wire through the toroid instead of the neutral or ground wire as indicated
below.
4. Secure the counter to the ZoneMaster PLUS®by removing the extra nuts located on the screw
studs to which the counter is to be attached.
5. Resetting the surge counter back to zero. The counter can be reset back to zero by simply
locating the button on the face of the counter and holding it down for a period of five seconds.
*SEE DRAWING BELOW FOR REFERENCE.

WARNING: Replace the defective module with a module having the same
color label and voltage rating.
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 side of the module. Remove
the mounting screws on the module. The protection module can now be removed.
Installation of the replacement module is the reverse of the above procedure. Final
step, check that all cable connections are secure and
screws are tightened. Do not overtighten.
