UNIT DESCRIPTION
Mains Module
The ESM 2 is designed to operate on a
mains supply of 185-265 volts ac (making it
ideal for use with low continental voltages).
The 40 amp RCD (Residual Current Device)
gives protection against earth faults and also
acts as the main switch.
The mains module also has three MCBs
(Miniature Circuit Breakers) which are
basically resettable mains fuses, to protect
against overcurrent. Allocation of the MCBs
is as follows:
MBC1- Sockets/Fanmaster (if fitted)
MCB2- Cascade/Lights (if fitted)
MCB3- Fridge/Charger
TRANSFORMER/CHARGER
The ESM 2 employs a fully automatic mains
to 12 volt dc transformer and battery
charger, able to operate with a wide range of
input voltages and provide a stable output
voltage even under load.
The unit can provide up to 12 amps
maximum, after which it will begin to shut
down to protect itself.
To use the charger simply place the rocker
switch to the ON position, at which point it
should illuminate and charging will
commence.
ROADS LIGHTS FUSES
The fuses are located on the front bulkhead
of the right hand front bed.

MODULE
PUMP SWITCH & INDICATOR
Included on this panel is a pump isolation
switch and pump running indicator. The
pump isolation switch is used to isolate
power to the water pump in the event of a
pump fault or merely as a safeguard against
unwanted pump operation. The red pump
running indicator will light up as a warning
when the water pump has been activated.
AUX SWITCH
This switch may be used to power any
auxiliary dc circuits the user may wish to
have added to the system.
Battery Condition Meter
This meter indicates the power remaining in
your caravan battery.
Readings should be taken as follows:
Green region - Fully charged
(no charge necessary
Yellow region - Adequate charge
(re-charge if desired)
Red region - Low charge
(turn on charger switch
to re-charge)
