Esm 2000 - Electrical Supply Module - Swift caravan Owner's Handbook Manual

Electrics
Caravan position
When in this position dc power is available
from the caravan battery to power all 12 volt
electric circuits.If the charger is switched ON
the caravan battery will be charged up via
the charger/transformer unit.
Central position
When in this position with the charger switch
ON, power is provided to all 12 volt circuits
via the charger/transformer only.
With the charger OFF all dc circuits are
isolated.
Note: The switch should be placed in this
position when the van is being towed.
42
Car position
Note: First of all the towing vehicle should
be electrically connected to the caravan via
the 12S socket.
The switch can be placed in this position
should the caravan battery become
discharged and no mains power is available.
ELECTRICAL SUPPLY MODULE
ESM2000
The ESM2000 Electrical Supply Module is a
230 volt ac and 12 volt dc power control
unit. It provides all the necessary features
for control of the electrics in a caravan. The
unit provides the following features:
Mains 230V ac - MAINS MODULE
with EARTH LEAKAGE PROTECTION
OVERCURRENT PROTECTION (RCD)
REVERSE POLARITY INDICATION
12 volt dc - FULLY AUTOMATIC
TRANSFORMER/CHARGER
with OVERCURRENT PROTECTION
SHORT CIRCUIT PROTECTION
SWITCH & FUSE MODULE
with BATTERY CHANGEOVER SWITCH
CHARGER ON/OFF SWITCH
8 FUSED DC OUTPUT CIRCUITS
UNIT DESCRIPTION
Mains Module
The ESM2000 is designed to operate on a
mains supply of 207 - 253 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 MCB's (Miniature Circuit
Breakers) which are basically resetable
mains fuses, to protect against overcurrent.
Allocation of the MCB's is as follows:-
For Abbey, Sterling and Swift models
MCB1 - SOCKETS/BLOWN-AIR HEATING
(if fitted)
MCB2 - WATER HEATER/LIGHTS (if fitted)
MCB3 - FRIDGE/CHARGER
For Bessacarr models
MCB1 - HEATING SYSTEM
MCB2 - SOCKETS
MCB3 - LIGHTS/FRIDGE/CHARGER
Using a generator
When using a generator in conjunction with
the ESM2000 the following must be
observed, failure to do so may result in
damage to the unit:
i) Always start the generator with the mains
isolator in the caravan turned off.
ii) Allow the generator to warm up for a few
minutes before energising power in the
caravan, as the output voltage can be
higher when cold.
