connect an AC power cord:

Step1 Connect one end of the supplied grounding cable to the grounding screw on the rear panel of the

chassis and the other end to the ground as near as possible.

Step2 Insert one end of the AC power cord to the AC power receptacle on the rear panel of the chassis, as

shown in Figure 41.

Step3 Connect the other end of the power cord to a power source.

Step4 Insert the two ends of the bail latch to the slots at the two sides of the AC power receptacle. Then push

the bail latch upwards, as shown in Figure 42.
