Grounding the switch by using the PE wire of an AC power
module
CAUTION:
•
Make sure the AC power module uses a three-wire cable with a protection wire, and the PE wire of
the AC power module is reliably grounded.
• Make sure the PE connector on the switch is connected securely to the PE wire of the AC power
module.
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 module, as shown in Figure 21 .
