Specifications

The RCD is fitted to provide protection
against earth faults and possible electric
shock. In the event of an earth fault which
would cause a current leaking to earth,
either directly or via the human body, the
unit should immediately trip and switch
OFF the supply. After elimination of the
fault it will be possible to manually reset
the RCD to the ON position by switching
the switch in an upward direction against
the spring pressure, and so restore the
supply again.
Periodically it is necessary to test the
operation of the RCD. This is achieved by
ensuring that it is switched in the ON
position with an electricity supply
connected and by pressing the test
button marked ‘T’. The unit should
immediately switch to the OFF position.
Provided this happens all is correct and
the switch should be returned to the ON
position, upwards and against the spring
pressure, to restore the supply back to
normal. The RCD also acts as the main
switch for the unit and if it is required to
switch off all circuits in the motorhome
this can be achieved by switching the
RCD to OFF.
FUSES
Replacement fuses must be made only
with fuses of equivalent values, and of the
same type as the originals. Correct values
of each fuse are clearly marked on them.
CAUTION
NEVER USE A FUSE OF HIGHER
RATING THAN THAT STATED.
REVERSE POLARITY
When connecting mains supply abroad,
the supply can be of reverse polarity. The
significance of this is that when
equipment is switched OFF it may not be
electrically isolated. The only certain way
of making sure equipment is safe is to
unplug it.
There are several proprietary makes of
equipment to check the polarity of mains
supply. This equipment is useful, mostly
for mains connection when overseas.
If reverse polarity occurs on site then
reverse the live & neutral connections
inside the plug on your mains cable.
Check before use.
If it can be achieved, it is preferable to
connect live to live, and neutral to neutral
to maintain full electrical protection.
GENERATORS
When using a generator to supply the P
C.II ensure that the actual output voltage
does not exceed the rated generator
output voltage, and the rated input
voltage of the P.C.il, otherwise internal
damage to the P.C.11 unit could occur.
N.B. Refer to the manufacturer’s
instruction book before use.
CAUTION: Take care not to expose the
battery to sparks or naked flames as
explosive gases may be present.
N.B. As with mains supply, switch off all
appliances and lights before
disconnecting the battery.
