Selecting the DC Cabling
Use the following guidelines when selecting cabling for the DC power supplies:
• Each DC power supply requires dedicated 55 A service.
• For DC power cables, use 4 AWG, high-strand-count copper wire cable.
Preparing the DC Cabling
Use the following guidelines when preparing cabling for the DC power supplies:
• Each DC power supply requires dedicated 60 A service.
• For DC power cables, use 4 AWG, high-strand-count copper wire cable with dual hole lugs that fit
over M6 (metric) terminals that are centered 0.625 inch (15.86 mm) apart.
• For convenience, the lock washers and nuts that you use to connect the source DC cables to the
power terminals are loosely mounted on the studs of the DC power supply.
NOTE
Add a length of heat-shrink tubing to prevent the crimp area on the lug from coming into contact with
the metal faceplate of the DC power supply.
Figure 108 shows the specifications of the lug that is used to connect the DC power cable to the DC
power supply.
