Grounding the switch in other grounding environments

Grounding an AC-powered switch

If the installation site has no grounding strips or earth ground, you ground an AC-powered switch through

the PE wire of the AC power supply.

Make sure the PE wire is well connected to the ground at the power distribution room or AC transformer

side, the switch PE terminal and the PE wire are well connected, and the three-wire input cable of the

grounding cable is used for the power supply cable. If the PE wire of the AC power supply is not

grounded at the power distribution room or AC transformer side, report the problem and reconstruct the

grounding system.

NOTE:

Use the grounding cable provided with the switch to connect the grounding strip in the equipment room.

Otherwise, the grounding effect may not be ensured, which easily causes damage to the switch.

CAUTION:

Make sure that the grounding cable has been properly connected before powering on the switch.

The V1910 Switch Series uses an external AC power system for its power supply. Follow these steps to

connect an AC power cord:

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

Step1

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

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