Manual
The SIPART DR22 is designed with a high electromagnetic compatibility (EMC) and has a
high resistance to HF interference. In order to maintain this high operational reliability we
recommend that all inductances (e.g. relays, contactors, motors) installed in the vicinity of or
connected to the controllers should be assembled with suitable suppressors (e.g. RC com-
binations)!
