Such  interference  can  be  avoided  by  adhering  to  the  following  recommendations
during installation:
-  The  device  should  not  be  installed  near  inductive  loads  (motors,  transformers,
contactors, etc.).
-  A  separate  power  line  is  recommended  (equipped  with  a  network  filter  if
necessary).

RC filter).
If the timer switch is to be used in combination with other devices in an installation, it is
necessary to verify that no parasitic disturbances will be caused by the group.
