Contactor assembly with relay control
The H1 terminals must not be bridged since otherwise all contactors will switch on when
only one contactor is to be controlled.
The H2 terminals should not be bridged since otherwise the internal connection from A1
to H2 will be overloaded in the event of a fault.
Control via relay outputs with common potential
Local control via SIMOCODE
Control via galvanically isolated / floating relay outputs
