E.l.c.bs must only be installed between mains supply and controller.
l E.l.c.bs can trip incorrectly because of
– capacitive leakage currents of the cable shields during operation
(especially with long, shielded motor cables),
– simultaneous connection of several controllers to the mains supply,
– use of additional RFI filters.

Strain relief with cable ties.
Use low-capacity motor cables! (Core/core ≤ 190 pF/m, core/shield ≤ 320
pF/m)
Use short motor cables if possible!

Connection terminals of motor temperature monitoring with PTC thermistor or
thermal contact (NC contact).
Route a separate cable (shielded) to X2/T1 and X2/T2 for the motor
temperature monitoring.
Activate the motor temperature monitoring under C0119 (e. g. C 0119 = 1)!
Route the control and mains cables separately from the motor cable!
