The color coding of the DC input power supply leads depends on the color coding of the DC power
source at your site. Typically, green or green/yellow is used for ground (GND), black is used for –48
V on negative (–) terminal and red is used for RTN on the positive (+) terminal. Make certain the
lead color coding you choose for the DC input power supply matches lead color coding used at the
DC power source.
For DC input power cables, select the appropriate wire gauge based on the National Electrical
Code (NEC) and local codes for 40-amp service at nominal DC input voltage (–48/–60 VDC).
Three pairs of cable leads, source DC (–) and source DC return (+), are required for each power
distribution unit (PDU). These cables are available from any commercial cable vendor. All input
power cables for the chassis should have the same wire gauge and cable lengths should match within
10 percent of deviation.
Each DC input power cable is terminated at the PDU by a cable lug. The cable lugs must be
dual-hole, and have a straight tongue. They must be able to fit over 1/4-inch terminal studs at
0.625-inch (15.88-mm) centers.
