CONGRATULATIONS! YOU HAVE JUST PURCHASED THE BEST SURGE 
PROTECTION IN THE INDUSTRY!

Adhering to these instructions guarantees maximum performance of this Protection 
device.

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.
