(Optional) Installing Power Cables for Three AC Dual–Live Wire Inputs
Step 1
Install short-circuit copper bars. Connect AC input terminals 3-L1 and 4-L1 by using short-
circuit copper bar 1. Connect AC input terminals 3-L2 and 4-L2 by using short-circuit copper
bar 2. Then secure the copper bars by using screws.
Step 2
Route AC input power cables through an appropriate cable hole on the rear of the subrack.
Step 3
Secure the AC input OT terminals to the corresponding short-circuit copper bars and AC
input wiring terminals, as shown in Figure 29.

Step 4
Reinstall the AC input protective cover.
Step 5
Reinstall the rear cover for the DCPS.
(Optional) Installing Power Cables for Two AC Dual–Live Wire Inputs
Step 1
Install short-circuit copper bars. Connect AC input terminals 1-L1 and 2-L1 by using short-
circuit copper bar 1. Connect 1-L2 and 2-L2 by using short-circuit copper bar 2. Connect 3-L1
and 4-L1 by using short-circuit copper bar 3. Connect 3-L2 and 4-L2 by using short-circuit
copper bar 4. Then secure the four copper bars by using screws.
Step 2
Route AC input power cables through an appropriate cable hole on the rear of the subrack.
Step 3
Secure the AC input OT terminals to the corresponding short-circuit copper bars, as shown in
Figure 30.
