5 Electrical connection
u
Disconnect the machine from the mains supply before installation; if necessary, also
disconnect any independently supplied input / output load circuits.
u
Observe the national and international regulations for the installation of electrical equipment.
u
Observe the requirements according to EN 60204.
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
The terminals may only be supplied with the signals specified in the technical data or on the
device label
Unconnected pins must not be connected to the cable harness and its individual cores must be
sealed.
ATTENTION
Reverse polarity protection not ensured in case of power supply SELV/PELV on VBB
30
and

)
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.
w
Damage to the device possible
u
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.
5.2 Connection accessories

5.3 Connection technology
Observe all notes on connection technology.
u
Note the device label.
u
Use M12 connectors with gold-plated contacts.
u
The M12 connection parts in the device comply with the ingress resistance requirements of the
standard EN 61076-2-101. To adhere to the protection rating, only cables certified to this standard
must be used. The system architect undertakes to ensure the ingress resistance of cables they
have cut to length.
