WARNING

Improper lifting can cause severe personal injury. Have sufficient manpower for lifting and

mounting the cabinet.

7. Remove the transfer switch from the box and remove the plastic covering.

WARNING

Unit will not be stable when supported only by bottom bolts. Additional support is required

to keep unit vertical while top bolts are installed.

8. Raise the cabinet and mount it on the two mounting bolts in the wall. Provide support for the cabinet

during installation.

NOTICE

Make sure wall mounting brackets are not bent during installation.

9. Install the two bottom mounting bolts, but do not tighten them. (Do not remove the cabinet support

until all bolts are installed.)

10. Push the cabinet against the wall. If the cabinet does not align flush against the wall, shim the

mounting bosses as required, using metal shims.

11. Tighten all mounting bolts.

3.2 Installation - Wiring

Refer to Reconnect AC Power (When Finished) on page 44 for component locations.

WARNING

AC voltages and currents present an electrical shock hazard that can cause severe personal

injury or death. Only trained and experienced personnel are to perform the following procedures.

CAUTION

Installation debris can cause equipment failure and damage. Use extreme care to keep drill chips

and filings out of the relays, contacts, and other parts of the automatic transfer switch when

mounting or connecting conduit. Screwdrivers should be used carefully to prevent damage to

components.

When installing conduit, observe the following precautions:

1. The RA Series transfer switch includes cutouts on the bottom of the cabinet for wiring. If you decide

to drill your own holes in the top of the cabinet instead of using the cutouts provided, cover

the transfer switch to prevent accidental entry of metal chips before beginning conduit

installation.

2. If using rigid conduit between the generator set and the transfer switch, install at least 2 feet (610

mm) of flexible conduit between the rigid conduit and generator set to absorb vibration.

3. Run control circuit wiring in separate conduit from the AC wiring; otherwise, induced currents could

cause operational problems within the switch. Cutouts are available through the bottom of the

cabinet. Refer to the switch outline drawings included in Appendix C on page 89.
