Install the Wall-Mounting Plates��
The top plate is used for mounting the back-up battery. The bottom plate is used to mount the power supply and distribution units. The plates can be rack-mounted using standard rack-mounting brackets. See 1145B2/1146B2 Mounting Arrangement.
- Locate one plate directly below the other one such that the AC power cord (6.5 feet [2�meters]) reaches the electrical outlet from a power supply mounted on the bottom plate. Both plates should be located so the raised letters are right side up.
NOTE: A maximum of four power supplies can be powered from one dedicated 110 volts AC, 20�amperes (or 230 volts AC, 15 amperes) feeder. Use only nonswitched outlets (outlets not connected to a wall switch).
- Secure the wall mounting plates to a standard 3/4-inch (2 centimeters) thick plywood mounting board. Each mounting plate comes with four #10 x 1/2-inch wood screws.
- The 1145B2 Power Supply is snap-fit onto the bottom wall mounting plate without tools.
- An installer-provided insulated ground wire, 16 AWG (#12) (1.2 square millimeters) or greater, is required to connect the power supply frame ground lug to an approved ground. The frame ground screw is located next to the AC outlet, to the left of the unit.
