Contactor combinations with relay control
Important Note
• The terminals H1 shouldn’t be bridged, otherwise all of the contactors will
close when only one contactor should close.
• The terminals H2 shouldn’t be bridged, otherwise the internal connection
of A1 to H2 can be overloaded in the event of a failure.
