NOTE!
Absence of reverse polarity protection
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 PELV, reverse polarity protection is not
ensured�
> Damage to the device
►
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�
The device is designed for supply via a mobile on-board system (12/24
V DC nominal voltage) or protective low voltage PELV according to the
technical data and national regulations� The supply is directly transferred to
the connected sensors/actuators without electrical separation�
►
Connect all required supply lines, GND connections and the shield connection�
6.2 Connection technology
Observe all notes on connection technology�
►
Note the device label�
►
Use M12 connectors with gold-plated contacts�
►
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
manufacturers undertake to ensure ingress resistance for cables which they cut
to length themselves�
►
Carry out the fitting according to the indications of the cable manufacturer� A
maximum of 10 Nm is permitted�
►
During installation, place the M12 connectors vertically so that the coupling nut
will not damage the thread�
