1145B power supply

Mountings

The back-up battery mounts on a top plate. The power supply and distribution units mount on a bottom plate. The plates are normally wall-mounted.

Installing the wall mounting

See Figure 3.

1.Locate one plate directly below the other with the raised letters right side up. Be sure that the AC power cord can reach the electrical outlet from the bottom plate. The power cord is about 7.5 ft. (2 m) long.

NOTE:

Up to 4 power supplies can draw current from one 110- or 230-VAC, 20- or 15-A feeder. Use only unswitched receptacles that are not shared with other equipment.

2.Secure the wall mounting plates to a 3/4-in. (2-cm) plywood mounting board using the four 1/2-in. #10 wood screws supplied with the plates.

3.Snap the 1145B power supply onto the bottom wall-mounting plate (no tools are needed).

4.Connect an insulated 17-AWG #12 (1.2-mm) ground wire (or better) between the ground lug on the power-supply frame and an approved ground.

The frame ground screw is located next to the AC receptacle, to the left of the unit.

5.Write the unit number and connectivity information on the front label, next to the LEDs.
