DETAILED STEPS
Step 1
Grasp the DC power supply by the two handles and carefully slide it into the chassis. Make sure you align the rear
connector to the backplane until it is fully seated.
Step 2
Tighten the captive screws on the power supply.
Step 3
Make certain that the chassis ground is connected before you begin installing the DC power supply.
Step 4
Locate the ground stud on the DC power supply for the GND connection which must be installed first and follow these
steps:
a) Using the grounding lug, replace the washers and Kepnut screw in the following order.
• ◦
Flat washer
◦
Grounding cable lug
◦
Kepnut screw
b)
Tighten the Kepnut screws (use the screwdriver to tighten the ground screw to a torque of 20+/–2 in-lbs / 2 per.) on
the power supply ground studs.
Step 5
Attach the other end of the ground cable to the site ground associated to the DC power supply system that you are working
on.
Step 6
Remove the plastic cover from the terminal block if it is still on.
Before you continue to install the terminal block ground wires, stop and perform Step 7. This is to prevent
any contact between the metal power lugs and plastic cover.
Caution
Step 7
You must wrap the positive and negative power cables with sleeving. Take each wire and cover the area from the lug to
the wire with heavy shrink sleeving as pointed out in callout 3 (see xref fig).
Step 8
For easier cable-management, insert the positive cable first. Replace the ground lug with cable in the following order as
shown in:
a) Flat Washer
b) Ground lug with positive wire
c) Kepnut screw
