20Step 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 InputsStep 1 Install short-circuit copper bars. Connect AC input terminals 1-L1 and 2-L1 by using short-circuitcopper bar 1. Connect 1-L2 and 2-L2 by using short-circuit copper bar 2. Connect 3-L1 and 4-L1by 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 inFigure 30.Figure 30 – Installing Power Cables for two AC dual-live Wire Inputs(1) Short-Circuit Copper Bar 1 (2) Short-Circuit Copper Bar 2 (3) Short-Circuit Copper Bar 3(4) Short-Circuit Copper Bar 4Step 4 Reinstall the AC input protective cover.Step 5 Reinstall the rear cover for the DCPS.(Optional) Installing Power Cables for One AC Dual–Live Wire InputStep 1 Install short-circuit copper bars. Connect AC input terminals 1-L1, 2-L1, 3-L1, and 4-L1 by usingshort-circuit copper bar 1. Connect AC input terminals 1-L2, 2-L2, 3-L2, and 4-L2 by usingshort-circuit copper bar 2. Then, secure the copper bars by using screws.Step 2 Route AC input 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 inFigure 31.
