Procedure 2-5
Installing a DC Power Supply
To install DC power a number of customer supplied components is required.
See “DC Power Supplies” on page 2-8 for more information.
Step Action
1 Remove the power supply module(s) from the packaging and inspect them
for damage.
2 Do one of the following:
• If a single power supply module is being installed, slide the power supply
module into slot PSA. Ensure that the PSB slot is covered by a filler plate.
(By default, the chassis has a filler plate installed over PSB.) See Figure
2-2 on page 2-6.
• If redundant power supply modules are being installed, use a Phillips
screwdriver to loosen the screw securing the filler plate in PSB. Remove
the filler plate and set aside. Then slide the power supply modules into
slot PSA and PSB. See Figure 2-2 on page 2-6.
3 Using a Phillips screwdriver, secure the module in place using the captive
hold down screw on the right of the module.
4 Prepare the DC power cord. The power cord should be a 14 AWG to 18 AWG
wire and should be of a length suitable for your installation. Remember to
allow the necessary slack for the cable to be properly retained between the
chassis and the terminal block. You will also need to install fork terminal
WARNING: Before performing the procedure, ensure that all power is off to the DC
circuit. Locate the circuit and switch it to the OFF position. Tape the circuit breaker
switch handle in the OFF position to prevent accidental closing of the circuit.
WARNING: A readily accessible disconnect device shall be incorporated
external to the equipment.
