Connecting the inputs EZ inputs switch electronically. Once you have connected a
contact via an input terminal, you can reuse it as a contact in
your EZ circuit diagram as often as you like.

pushbuttons, switches, relay or contactor contacts, proximity

Caution!
Connect the inputs for AC devices in compliance with the
safety regulations of the VDE, IEC, UL and CSA. Use the
same phase conductor for the input power feed, otherwise
EZ will not detect the switching level and may be damaged
or destroyed by overvoltage.
