Section 3: Installation

Introduction to Installation

This equipment has been wired and tested at the factory.

Installing the switch includes the following procedures:

• Mounting the enclosure.

• Connecting power source and load leads.

• Connecting the generator start and sensing circuit.

• Connecting any auxiliary contact (if needed).

• Testing functions.

Mounting

Mounting dimensions for the transfer switch enclosure

are in this manual. Enclosures are typically wall-

mounted. See Drawings and Diagrams.

This transfer switch is mounted in a UL type 3R

enclosure. It can be mounted outside or inside and should

be based on the layout of installation, convenience and

proximity to the utility supply and load center.

Install the transfer switch as close as possible to the

electrical loads that are to be connected to it. Mount the

switch vertically to a rigid supporting structure. To prevent

switch distortion, level all mounting points. If necessary,

use washers behind mounting holes to level the unit.
