Introduction

This document explains how to install the ZoneDefender PRO Series of AC Panel
Surge Protective Devices.

Installation Instructions

Mounting

The suppressor should be mounted as close to the panel and wire connections as pos-
sible. The shortest and most direct wire connections will ensure best performance. Use
the four mounting holes located on the tabs to secure unit to a solid fl at surface. The
type of hardware used to mount the Zone Defender PRO will depend on the mounting
structure and are not included with the unit.

AC Power Connections

Proper wiring techniques associated with the National Electrical Codes should be
followed. The use of a 30 AMP minimum circuit breaker is required in the event the
connection wires short or the Zone Defender PRO needs servicing.
The ¾" nipple on the Zone Defender PRO can be inserted directly into an existing
panel knockout to ease the wire connections between the panel and the Zone Defender
PRO. If the mounting location prevents this type of installation proper conduit fi ttings
should be used in order to protect the connecting wires.
When making the connections, cut each conductor as short as possible. Avoid large
loops and sharp bends in the wire. Bind all connecting wires tightly together throughout
the wire run from the Zone Defender PRO to the panel. Connect the BLACK wires
to the phase conductors, connect the WHITE wire to the neutral bus and connect the
GREEN wire to the ground bus.
INCORRECT INSTALLATION WILL IMPAIR THE EFFECTIVENESS
OF AC PANEL SURGE PROTECTORS. Particularly important is the length and
routing of the connecting leads.
