ECM ELECTRICAL CONTROL
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.

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 locker.

ESM2
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:
