General guidelines
}
Do not lay the connecting cable near or in contact with cables that carry high or highly
volatile currents.
}
Use separate cables to connect the wires to the OSSDs on different safety light curtains
or safety switches.
}
Do
not
connect contacts OSSD1 and OSSD2 in series or in parallel.
}
For supply voltage, use only PELV/SELV power supplies that have a voltage buffer in ac-
cordance with EN 60204-1.
}
The power supply must be able to bridge a short (20 ms) supply voltage failure in accord-
ance with EN 61496-1.
}
SELV power supply
– Do
not
connect the safety light curtain housing to the earth conductor or the protect-
ive conductor. The transmitters and receivers must be electrically isolated from the
machine/system. The use of the flexible bracket (swivel mount) provides this electrical
isolation.
