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.
