Each DC power supply input requires either a 48 VDC or 60 VDC power
source supplied by three 10 AWG (American Wire Gauge) copper wires.
These wires must be terminated with either ring or spade terminals that
accept a #6 screw.
3.4.1 Connecting a 6C205-2 to a 48/60 VDC Power

Figure 3-7 48/60 VDC Power Supply Connections
1. Connect the ground terminal of the DC input power strip to an
appropriate earth ground.
2. Refer to Figure 3-7 for the proper connections to a 48/60 VDC power
source. Then connect the output leads of the 48/60 VDC power source
being used to the negative (-) and positive (+) terminals on the DC
input power strip.
3. Repeat steps 1 and 2, if applicable, to connect a 48/60 VDC power
source to a second 6C205-2 installed in the chassis.
4. Restore power to the 48/60 VDC power sources.
5. Press the on/off power switch of each power switch to on.
