Chapter 3 Using DC Power 15
Assembling the DC Input Power Cable
▼
To Assemble the DC Input Power Cable
1. Determine how many DC input power cables you will need from each DC power
source.
2.Turn off power to the DC power source through the circuit breakers.
Caution –
Do not proceed with these instructions until you have turned off the
power to the DC power source through the circuit breakers.
3. Take a DC connector from the ship kit.
4. Locate the three wires coming from the DC power source that will be used in the
connection to your unit:
■
–48 V Supply
■
Chassis ground
■
–48 V Return
5. Strip 8 mm (0.31 inches) of insulation from each of the wires coming from the DC
power source (see
FIGURE 3-1
).
Do not strip more than 8 mm (0.31 inches) from each wire. Doing so will leave
uninsulated wire exposed from the DC connector after the assembly is complete.

6. Insert the tip of the cage clamp operating lever into the rectangular hole directly
above the hole in the DC connector where you want to insert the first wire and
press down on the cage clamp operating lever (see
FIGURE 3-2
).
This opens the cage clamp for this section of the DC connector.
