A supply group always consists of 2 neighboring channels, starting from channel 0. Channels 0 and
1, 2 and 3, ... 14 and 15 therefore each form a supply group.

Reclosing at full load is not guaranteed after a short circuit. Measures for dealing with this problem:
● Change the signal at the output or
● Interrupt the load voltage of the module
● Briefly disconnect the load from the output
