Reverse
Polarity light is
illuminated on
PSU
Mains Supply reversed? The reverse polarity light is designed to
illuminatewhentheLiveandNeutralsupply
has been reversed / crossed over. If the light
illuminates there is a problem with the site
supply or the cable connecting the supply to
your vehicle. The light is designed to work
on UK electrical supplies (where the neutral
conductor is connected to earth at the sub
station). If you are using your vehicle outside
the UK this light may illuminate when no fault
exists. In these cases consult the site warden
for advise.
Generator being used ‘The Reverse Polarity warning light is on when
using my Generator’.
This is a normal side effect when using some
types of generator. Instead of connecting the
neutral conductor to earth, some generators
centre tap the earth connection making
both neutral and live conductors 110v above
earth. This 110v difference causes the neon
polarity indicator to illuminate. In most cases
it is still safe to use the generator, but please
consult the generator handbook for further
information.
