Wiring
Please note:
}
}
The max. cable length l
max
in the input circuit is calculated from
–
the max. cable capacitance at the safety outputs (see
).
–
the minimum permitted supply voltage at the sensor (19.2 V).
}
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.
}
The supply voltage to the safety switch must be protected with a 2 A to 4 A quick-acting
fuse.
}
Ensure the wiring and EMC requirements of EN 60204-1 are met.
}
When connecting in series, consider the requirements of manipulation protection and
the protection against bypassing or from overriding the safety switch (EN ISO 14119).
}
When the safety inputs of the safety switch are controlled by an upstream device, and
they are not wired with 24 V,
–
They must be monitored for shorts across the contacts in dependence of the Per-
formance Level or SIL level to be achieved
or
–
The the faults at the safety inputs that can occur by shorts across contact will have
to be excluded by suitable measures (e.g. wiring in accordance with EN 602041).
