8. Relay connection and suppression of their inductive load

This is the recommended output connection of the VArio DIN Module for connection of inductive
load inside a breaker box
(diagram is valid for one output = in this case the “Attraction” contact).
Connect the other outputs with inductive load accordingly.
The outputs are designed for general use as potential-free contacts, which provides for a wide range
of utilization.
For DC coil switching / inductive load suppressing, we strongly recommend using a parallel diode
connection (in closing direction).
Following these rules and recommendations will result in significant lifetime extension of contacts
and relays in the DIN module. In addition, the failure rate of electronic systems placed inside the
breaker box, which could be caused by disturbances from inductive load switching, will be
substantially reduced (e.g. electromotors, the contactor control coil transformers and relays).
