Notes on wiring

Please observe the following when wiring:
Power supply
}
When selecting the power supply, please refer to the requirements stated under "Tech-
nical Details".
}
The power supply used to supply the PSENvip transmitter and receiver must be able to
bridge a power outage of 10 ms. This requirement comes from EN 61496-1:2004: Safety
of machinery – Electrosensitive protective equipment. Supply interruptions on the PSEN-
vip that cannot be bridged by the PSENvip will always lead to a safe condition (OSSD1,
OSSD2 in OFF condition).
}
Overload protection must be provided. Use a circuit breaker with characteristic C, 4 A or 6
A, depending on the inrush current. Please refer to the recommendations of the power
supply manufacturer.
Cable
} The transmitter and receiver should only be connected using shielded cables (available
as accessories). The cable shield is connected to the metal coupling on the M12 connect-
ors.
}
Earth the cable shield connection within the control cabinet, e.g. on a bus bar.
} The ready-made cables from Pilz should preferably be used for connecting The PSENvip
(see chapter 11, "Technical Details").
} Protect the cable from mechanical damage. Lay the cable in such a way that wire short
circuits are excluded. If the cable is not protected through the machine, it should be laid in
armoured hose.

CAUTION!
Unintended machine start up!
Voltage should be removed from the whole machine and PSENvip during
wiring.
WARNING!
Electric shock!
Safe electrical isolation must be ensured for the external power supply gen-
erating the 24 V supply voltage and the voltages to the inputs on the PSEN-
vip. Failure to do so could result in electric shock. The power supplies must
comply with EN 60950-1 and EN 61558-2-6.
