When installed vertically: Secure the unit by using a fixing element (e.g. retaining bracket
or end angle).

Outputs 13-14, 23-24, 33-34, 43-44, 53-54, 63-64 are safety contacts; outputs 71-72,
81-82, 91-92, 01-02 are auxiliary contacts (e.g. for display).
}
Do
not
use auxiliary contacts 71-72, 81-82, 91-92, 01-02 for safety circuits!
}
Do not connect undesignated terminals.
}
To prevent contact welding, a fuse should be connected before the output contacts (see

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.
}
Do not switch low currents using contacts that have been used previously with high cur-
rents.
}
Adequate protection must be provided on all output contacts with capacitive and inductive
loads.
}
When connecting magnetically operated, reed proximity switches, ensure that the max.
peak inrush current (on the input circuit) does not overload the proximity switch.

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 runs, we recommend the
following test after the installation of the device:
1. Unit ready for operation (output contacts closed)
2. Short circuit the test terminals S12, S22 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.
