QUICK START GUIDE
Step 1 - Mount Shelf
Prepare the shelf for mounting to the frame.
1. Reposition mounting ears as required - 3 screws each.
Torque to 2.8Nm (25 in-lb) - Phillips screwdriver.
2. Position the shelf immediately above the rectifier shelf
with controller (if present).
3. Install Inter-Shelf brackets between adjacent shelves
(optional).
Torque to 2.8Nm (25 in-lb) - Phillips screwdriver.
Mount the shelf to the frame.
1. Attach shelf to the frame using a minimum of four
screws (two on each side) - 12- 24 (provided).
Torque to 4Nm (35 in-lb) - 5/16” (8mm) socket.
Step 2 - Ground Chassis
Notes:
1 Lug landings are M5 on 5/8” (16mm) centers (lug not
provided)
2 6mm2 (10AWG) recommended.
3 Some applications may rely on frame mounting screws
for shelf ground omitting the shelf ground cable
Torque to 4Nm (35 in-lb) - 8mm (8mm) socket.
Step 3 - Connect System DC Reference
(CO) Ground
Make one connection to a power system (SPS, NE, CPL,
etc.). No connection to a stand-alone, remote distribution
shelf. Connections are to the left-most position on the
Load Return bus - M6 lug ( not provided).
10mm2 recommended
Torque to 4.0 Nm (35 in-lb) - 10 mm socket.
Step 4 - Connect Shelf DC Input
Connections are on the rear under covers.
Bus Connection - to an adjacent rectifier shelf
Install inter-shelf buses joining -48V and RETURN bus
connections of all adjacent shelves.
Cable Connection - Stand-alone Shelf
CAUTION: Verify battery voltage and polarity with a
voltmeter before proceeding.
Lug Landings - 2 x 1/4” on 5/8” center, 0.7” (18mm) max.
tongue width. Connect cables with suitable lugs to -48V &
RETURN. Torque to 4Nm (35in-lb) - 8mm (8mm)socket.
