3.2.1 Connecting the AC Power Cord

I. AC power source socket (recommended)
You are recommended to use a single-phase three-wire power socket with a neutral
contact or a general purpose PC power socket, making sure that the neutral point is
well connected to building ground. Normally, the neutral point of the power source in a
building has been buried in the ground during the building construction and cable
routing stage. Still, you must make sure that the power source of the build is reliably
grounded.

II. Connecting the AC Power Cord
Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear
of the chassis and the other end to the ground as near as possible.
Step 2: Connect one end of the power cord to the power input on the rear panel of the
chassis, and plug the other end to the AC power input of the power source.
Step 3: Install the power cord retainer for the AC power cord. Insert the two ends of the
power cord retainer into the slots at both sides of the AC power input, and then set the
power cord into the notch of the power cord retainer.
