Grounding the switch through the PE wire of an AC power
supply
CAUTION:
Make sure the AC power supply uses a three-wire cable with a protection wire, and the PE wire of
the AC power supply is reliably grounded at the power distribution room or AC power supply
transformer side. In addition, make sure the PE connector on the switch is reliably connected to the
PE wire of the AC power supply.
If the switch is AC powered and no grounding strip is available at the installation site, you can ground
the switch through the PE wire of the AC power supply, as shown in
