Grounding the switch by using the AC power cord
If the installation site does not have grounding strips, you can ground an AC-powered switch through
the protective earth (PE) wire of the power cord. Make sure the following requirements are met:
•
The power cord has a PE terminal.
•
The ground contact in the power outlet is securely connected to the ground in the power
distribution room or on the AC transformer side.
•
The power cord is securely connected to the power outlet.
NOTE:
If the ground contact in the power outlet is not connected to the ground, report the problem and
reconstruct the grounding system.
