Section 2 Installation
For units with hinged doors, open the door and
disconnect the cable plug that connects the front door
components to the internal components. Disconnect
the grounding wire between the door and the enclosure.
Squeeze the release pins on each hinge together and
remove the door. See Figure 2-6. Set the door out of the
way to protect the controls.
Vertically mount 30- through 400-amp transfer switches
to a wall or other rigid vertical supporting structure. Use
the template on the shipping carton to locate the
mounting holes in the wall. Level the template before
marking and drilling the holes. Clearance holes through
the back of each enclosure are provided for mounting.
Use shims to plumb the enclosure. Verify that the door
hinges are vertical to avoid distortion of the enclosure or
door.
