3) Plug the other end into the AC power busbar, which is connected to the AC power supply in the
equipment room.
Since the busbars used in equipment rooms are typically for 10-A power cables, but the PSR1400-A,
PSR2800-ACV, and PSR6000-ACV power modules require 16-A AC power cables, you need to
provide a busbar suitable for 16-A power cables. Refer to Appendix B "AC Power Cables Used in
Different Countries or Regions" for AC power cable specifications.

To connect the DC power cable for the PSR320-D, proceed as follows:
1) Remove the protection cover from the power module.
2) Loosen the fastening screw on the wiring terminal with a Phillips screwdriver.
3) Connect the end of the blue DC power cable marked with – to the negative terminal (–) on the
power module and fasten the screw.
4) Connect the end of the black DC power cable marked with + to the RTN (+) terminal on the power
module and fasten the screw.
5) Put the protection cover on the wiring terminals.
6) Connect the other ends of the DC power cables to the wiring terminals that provide a power supply
to the switch.
