5 Electrical connection
►
Disconnect the machine from the mains supply before installation; if
necessary, also disconnect any independently supplied input / output
load circuits� The same applies to the M12 connectors!
►
Observe the national and international regulations for the installation of
electrical equipment�
Accessible surfaces of the device are insulated from the circuits with basic
insulation to IEC 61010-1 (secondary circuit with max. 32 V DC, supplied from the
mains circuit up to 300 V of overvoltage category II).
GND of the supply is connected via EMC suppression capacitors on the shield
connection (metal housing) of the device.
The external wiring has to be carried out in a way that ensures the required
separation from other circuits�
5.1 Wiring
Wiring
Only the signals indicated in the technical data or on the device label may
be supplied to the terminals�
Unconnected connector pins need to have sealing of the individual cores�
NOTE!
Reverse polarity protection is not ensured in case of supply from the
power supply SELV/PELV to VBB
30
and VBB
0
)
Reverse polarity protection is only ensured in case of supply via the
on-board system (via a battery), if the polarity of the supply is reversed
as a whole (battery connected incorrectly). The basic principle of
the reverse polarity protection is that the upstream fuses are quickly
switched off in case of excessive current�
In case of supply via SELV/PELV, reverse polarity protection is not
ensured�
> Damage to the device possible
►
Ensure that the ends of the cables are properly connected to the
connector before connecting the latter to the device, also in case of
supply via the on-board system�
