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�
> The device may be damaged
►
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�
