this connection work requires expertise, the work must be conducted by qualified
personnel. The steps are as follows:
1. Procure the DC input power cable in compliance with the specifications shown
below. When the power supply is duplexed (redundant), procure two cables.
Cord structure: 3-wire
AWG No. of each conductor (determined by ampacity): 10
Cord diameter (determined by cable clamp): 16mm or smaller
Size of wire-binding screw on terminal board: M5
2. Ensure that the breaker switch in the front end of the chassis is in the O (out)
position. When the power supply is duplexed, make sure in two positions.
3. In the rear end of the chassis, detach the cover from the input unit and connect
each terminal wire of the input power cable firmly to the terminal board and the
ground. See Figure 6-57 for the dimensions of the terminal board and the
terminal wire. When the power supply is duplexed, repeat the connection work in
two positions.
4. Fix the input power cable with the cable clamp. When the power supply is
duplexed, repeat the fixation in two positions. Then, attach the cover back to the
input unit.
