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’’ on page 149
.
1 Locate one plate directly below the other one such that the AC power cord (6.5 feet or 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 VAC, 20 amp
(or 230 VAC, 15 amp) feeder. Use only unswitched outlets (outlets not connected to a wall
switch).
2 Secure the wall mounting plates to a standard 3/4 inch (2 cm) thick plywood mounting
board. Each mounting plate comes with four #10 x 1/2-inch wood screws.
3 The 1145B2 Power Supply is snap-fit onto the bottom wall mounting plate without tools.
4 An installer-provided insulated ground wire, 16 AWG (#12) (1.2 mm
2
) 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.
Mount the 1146B2 Power Distribution Unit
See the 1146B2 Power Distribution Unit in ‘‘Expanded Power Distribution Unit’’ on page 150
.
1 Insert and securely tighten the two supplied #8-32 x 1/2-inch shoulder screws (they have
an unthreaded section at the top) into the top holes designated for 1146B2 Power
Distribution Unit on the bottom plate. Mount the unit on these two shoulder screws,
using the key holes on the back of the unit.
2 Secure the unit by inserting the #8-32 x 1 inch screw through the bottom of the unit (just
above the wire clips) into the plate and tighten.
3 Set the battery back-up switch option to the 1-32 (down) position to provide battery
back-up to all outputs.
4 Connect the power distribution unit to the power supply with the power cable. Refer to
the power supply’s right-hand label to locate the output power connection.
Install the Battery Mounting/Wiring
Three types of back-up batteries are used. See ‘‘Back-Up Battery Rating’’ on page 152
for the
battery type and rating.
1 Insert two #10-32 x 1/2-inch shoulder screws into the top designated battery holes on the
wall mounting plate. Lightly screw in but do not tighten.
2 Place the keyhole slots in the battery bracket on these two screws. The battery cord exits
from the right of the bracket. Make sure the label on the battery is visible. Tighten the
screws securely.
