Reverse
Polarity
light is
illuminated
on PSU
Mains Supply
reversed?
The reverse polarity light is designed to
illuminate when the Live and Neutral supply
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 substation). 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 advice.
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.
