} 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 4A quick-acting
fuse.
} Ensure the wiring and EMC requirements of IEC 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 (ENISO14119).
