Inverting
The inversion of the relays
“
K1
”
and
“
K2
”
is set at the factory to
“
OFF
”
(when a function
is programmed).
For switching inversion to
“
ON
”
(switching behaviour dependent on assigned function).
The relays can only pull up basically when the voltage supply of the electronics is
working. Three-phase current devices must have at least 2 line phases!
