Notes on wiring
Please observe the following when wiring:
CAUTION!
Unintended machine start up!
Voltage should be removed from the whole machine and PSENvip during
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.
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.
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.
