Note: The positive break applies to the NC
wires of the type 6 contacts only. Connections
to safety circuits should be made to the black
wires only. Connections to safety circuits
should NOT be made using the type 1
contacts. Slow action contacts are break
before make. To ensure positive breaking of
the NC contacts on the type 6 models, exceed
the pre-travel by 1.5mm or 25˚, according to
the model.
