Switch is designed for wall mounting applications. There are flanges at top and bottom on the

back of the enclosure, allowing the switch to be mounted to any flat surface that is capable of

supporting the load. Simply choose a sturdy location, and secure the unit to the wall using

appropriately sized hardware for the pre-drilled mounting holes on the flanges of the enclosure.

Always follow all applicable local and national electrical and building codes when

installing this unit.

Note: Consider your plans for bringing in supply power

and running secondary power when mounting, and be

sure to leave clearance for all necessary wiring and

operations, as well as for opening the door.

Wiring

Only a licensed electrician should install this product, in all locations, especially in outdoor areas where

weatherproofing may be required.

Note: Always check product nameplate or labeling for voltage ratings! Follow all applicable local and National

Electrical and building code when installing.

There are two types of installation methods: Conduit installation or cable installation. If the enclosure is complete with

factory installed entry hardware, run all your wiring through entry hardware and refer to the wiring diagram included with

your unit for completing wiring connections.

If the enclosure does not include entry hardware, select the appropriate hubs or cable connectors and install them per the

IOM included with the hardware.

Installation of approved conduit hubs or cable connectors

CAUTION: FIELD INSTALLED OPENINGS:

For field-installed openings, use a hole saw, metal drill bit, or pneumatic type punch to create an appropriately sized hole

for mounting your selected hardware. Always wear safety glasses and protective clothing when working.

Conduit/Cable Installation

In situations where the metal cable connector and conduit hubs must be bonded to the ground system, this can be

accomplished by installing them either by method 1 or method 2 as shown.

Method 1: Enclosures with flange plates using threaded

openings through the flange plate and standard

locknuts. Flange Plate must be connected to the

internal grounding system using jumper wires.

Refer to IOM sheet of cable connector for proper installation

Method 2: Enclosures without flange plates using a hole

“through the enclosure” with grounding

locknut.

These locknuts must be bonded between each other and to the

grounding system using jumper wires. After the entry hardware is

installed, connect the appropriate conduit or cable.

Note: All unused enclosure openings must be closed using

approved close-up plugs with standard locknuts.

IMPORTANT: When connecting conductors:

•Strip the wire so that the insulation covers the wire up to the

terminal.

•Make sure all wires are connected to the correct terminals,

per the wiring diagram.

•Tighten all terminal blocks/screws.
