Wiring
Please note:
} You must comply with the specifications stated in the technical details (see Technical
details: System with normal actuator [ 23], System with free-moving
actuator [ 27]).
} The power supply must meet the regulations for extra low voltages with protective sep-
aration (SELV, PELV).
} The inputs and outputs of the safety switch must have a protective separation to
voltages over 60 VDC.
INFORMATION
Only use safety relays with a 24 VDC supply voltage. Safety relays with a
wide-range power supply or in AC device versions have internal potential
isolation and are not suitable as evaluation devices.
} Ensure the wiring and EMC requirements of EN 60204-1 are met.
Guidelines for cable length
The max. cable length depends on the voltage drop at the safety switches. The level of
voltage drop is determined by the:
} Cable resistance
} Current of the device and the current load of the outputs
If the level of the supply voltage at the device connector falls below the minimum permitted
value (see Technical details: System with normal actuator [ 23], System with free-mov-
ing actuator [ 27]), the locking magnet is no longer activated reliably. The "Lock" LED
registers an error when guard locking.
Possible remedies:
} Set the supply voltage constantly to the upper tolerance range (see Technical details:
System with normal actuator [ 23], System with free-moving actuator [ 27]).
} Select a higher conductor cross section
} Reduce load at the outputs, e.g. with evaluation device PNOZe1.1p
Recommended cable cross sections
