'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 con-
necting 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.
Check batteries and fuses, turn PSU
shutdown switch and charger switch on
and ensure mains supply is connected.
Check control panel connecting lead at
PSU and behind Control Panel.
