9.17 Instructions for measuring the current door opener

If you would like to control an already existing door opener and do not have any information about
the current consumption, determine whether the maximum power consumption will overload the
relay before connecting to the door video module relay.
To do this, measure the power consumption using a multimeter. Separate a live cable and switch
the ammeter in between (in series).
