Installation
Observe the following when using Ground Fault Circuit Interrupters (GFCIs):
• Installation of GFCI only between supplying mains and controller.
• The GFCI can be activated by:
- capacitive leakage currents between the cable screens during operation (especially with long,
screened motor cables)
- connecting several controllers to the mains at the same time
- RFI filters
