Section 2: 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. Se

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.

Open Enclosure

See 

Figure 2-1

. First, remove outer cover (A):

1.

Remove two thumb screws (B).

2.

Slide slot (C) over retention tab.

3.

Lower cover until clear of top flange (D), and pull
away from enclosure.

Remove inner panel (E):

4.

Loosen nut (F).

5.

Grasp inner panel at two cutouts (G—left and
right). Tilt inner panel as shown, passing nut
