3.2.5 Mounting Method

RA Series transfer switches are mounted to a wall. Enough room must be allowed to remove the door

panel for inspection and servicing of the switch, as per NEC and local codes.

3.2.5.1 Wall Mounting

1. Make sure that the wall where the transfer switch is to be mounted is suitable to hold firmly the

weight and size of the transfer switch, within a reasonable safety factor.

2. Check the location to be sure that no wires or plumbing, gas, or exhaust lines run behind the wall.

3. Make sure that the anchorage fasteners used to bolt the switch to the wall are strong enough to

withstand the switch weight and its vibration during operation, within a reasonable safety factor.

4. Use four 1/4 inch bolts for wall mounting. Measure and mark the wall for drilling.

5. Install two mounting bolts in the wall for the top cabinet mounting keyholes.

WARNING

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

mounting the cabinet.

6. Remove the transfer switch from the box.

7. Raise the cabinet and mount it on the two mounting bolts in the wall.

8. Install the two bottom mounting bolts, but do not tighten them.

9. 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.

10. Tighten all mounting bolts.

3.3 Installation - Wiring

Refer to Reconnect AC Power (When Finished) on page 26 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.
