Use a three-terminal, single-phase power connector with a grounding contact.
Ground the power supply reliably. Normally, the grounding contact of the power supply system
in a building was buried during construction and cabling.
Before connecting the AC power cord, make sure that the power supply of the building is well
grounded.

Step2
Move the AC power switch on the power modules to the OFF position.
Step3
Move the bail latch to the left.
Step4
Connect one end of the supplied AC power cord to the power socket on the router, and the
other end to an AC power outlet.
Step5
Move the bail latch to the right to hold the power cord in position.
Step6
Move the power switches on all power modules to the ON position.
Step7
