EMC requirements
Please note:
}
The power supply must meet the regulations for extra low voltages with protective separ-
ation (SELV, PELV).
}
The inputs and outputs of the safety switch must have a protective separation to voltages
over 60 V AC.
}
The supply voltage has to be at the safety switch terminals within the indicated tolerances
(see Technical details).
}
the supply voltage of the safety switch must be secured with a fuse of type quick between
2 A and 10 A.
}
The electrical installation must be performed in accordance with IEC/EN 60204.
}
The assured release distance (S
aO
) can be influenced by external influences (e.g.: tem-
perature, dirt, EMC) (see Technical details).
INFORMATION
Safety relays with a wide-range power supply or in AC device versions have
internal potential isolation and are not suitable as evaluation devices. Only
safety relays with a 24 VDC supply voltage are suitable.
