6.1 General wiring guidelines
Please note:
} If short circuits occur between the cable from the output to the load and a supply line, it
will no longer be possible to switch off the load. Possible remedies:
} Use separate multicore cable for supply voltages
– Use dual actuators, e.g. two contactors in series
– Use an additional shutdown device such as a main contactor
} Use appropriate wiring to exclude short circuits between the outputs!
} With single­channel operation for applications up to Category 3 in accordance with EN
954­1: use a feedback loop!
} When used for Category 4 applications in accordance with EN 954­1: connect two actu­
ators connected in series to two different outputs!
} The actuators may be connected using unshielded cables.
} The outputs do not need suppression for inductive loads.
} Use copper wiring.
} The terminal configuration as stated on the front plate applies for base modules with C­
rail. The terminal configuration as stated in the technical documentation applies for all
other base modules.
6.1.1 Mechanical connection of the base modules
Procedure:
} Use a flat blade screwdriver (DIN 5264­A)!
DIN 5264-A
} Strip the wire back 8 mm.
} If necessary, label the connection level with a colour marker [3].
} Base module with screw terminals:
– Use a screwdriver to loosen the screw on the screw terminal [1]
– Insert the stripped cable into the round fixing hole [2], as far as it will go.
– Tighten up the screw on the screw terminal.
– Check that the cable is firmly seated.
