Wiring
Please note:
} Information given in the "Technical details [ 16]" must be followed.
} Delivery status of units with screw terminals: Link between S11-S12 (dual-channel input
circuit) and link between Y39-Y40 (reset circuit)
} Outputs 13-14, 23-24, 33-34 are instantaneous safety contacts, outputs 57-58, 67-68 are
delay-on de-energisation safety contacts, output 41-42 is an instantaneous auxiliary con-
tact (e.g. for display).
} Auxiliary contact 41-42 shouldnot be used for safety circuits!
} Do not connect undesignated terminals.
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 16]).

} Use copper wiring with a temperature stability of 60/75 °C.
} To prevent EMC interferences (particularly common-mode interferences) the measures
described in EN60204-1 must be executed. This includes the separate routing of cables
of the control circuits (input, start and feedback loop) from other cables for energy trans-
mission or the shielding of cables, for example.
} Adequate protection must be provided on all output contacts with capacitive and inductive
loads.
} On units with U
B
24 – 240 VAC/DC: Connect operational earth terminal to functional
earth.
} Do not switch low currents using contacts that have been used previously with high cur-
rents.
} On 24 VDC devices:
The power supply must comply with the regulations for extra low voltages with protective
electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
Important for detection of shorts across contacts:
As this function for detecting shorts across contacts is not failsafe, it is tested by Pilz during
the final control check. If there is a danger of exceeding the cable length, we recommend
the following test once the unit is installed:
1. Unit ready for operation (output contacts closed)
2. Short circuit the test terminals S22, S32 for detecting shorts across the inputs.
3. The unit‘s fuse must be triggered and the output contacts must open. Cable lengths in
the scale of the maximum length can delay the fuse triggering for up to 2 minutes.
4. Reset the fuse: Remove the short circuit and switch off the supply voltage for approx. 1
minute.
