azard due to electrical voltage
Death or severe injury
b
Make sure that the machine and the connecting cables of the safety locking
device are and remain disconnected from the power supply during the electrical
installation.
DANGER
Incor
rect safety locking device connection
Loss of safety function
b
With insulation material or connection slots, pay attention to the temperature
resistance and mechanical load capability.
b
If different voltages are used between the contact pairs and the magnet coil (e.g.
230 V and 24 V), when wiring in the terminal compartment, make sure safe sepa‐
ration is always present.
b
For safety functions, use only safe contacts for locking device monitoring and door
monitoring.

T
o ensure a secure contact, strip the individual wires back about 6 mm (± 1 mm).
6.1.1 Notes on cULus
Devices with cable entry
F
or use according to the requirements of cULus, a copper wire (60/75 °C) must be
used.
Devices with plug connector
For use according to the requirements of cULus, a class 2 voltage supply according to
UL 1310 must be used. Connecting cables of the safety locking device installed at the
place of use must always be 50.8 mm away the following:
•
Moving and fixed cables without suitable insulation material which have the same
or higher dielectric strength compared to the other relevant system parts
•
Active system parts without insulation which work with a voltage supply of over
150 V
