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 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 advice.
Reverse Polarity
light is
illuminated on
PSU
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.
Control Panel has no
