If multiple safety components are wired in series, the Performance

4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
The contact labelling can be found in the wiring compartment of the
switch. For the cable entry, suitable cable glands with an appropriate
degree of protection must be used. The cables must be laid correctly in
the wiring compartment of the switch. For foot switches with 1 foot ped-
al, the M20 x 1.5 cable entry is available, for foot switches with 2 foot
pedals, 2x M25 x 1.5. The non-used cable entry must be sealed with
blanking plugs. After wiring, the wiring compartment of the switch must
definately be cleaned (e.g. removal of cables residues), considering
that foreign bodies can affect the switching behaviour. The tightening
torque for the cover screws is min. 1.8 Nm.
