Thereforefrequency and output voltage can riseabove the specification of the machinedata plate i.e. 240v at 50Hz, this may40cause damage to electrical/electronicequipment (such as battery chargers).• A generator should always be run for afew minutes prior to connection with thecaravan or motorhome electrics, to allowit to warm up and the output to settle to asteady level.• The AC output of generators is oftenderived from an AC alternator, rectified toDC then inverted back to AC. In essencethis means the output sinewave may notbe very smooth and may not runsophisticated electronics efficiently. Someof the new wave of gensets are moresophisticated in their production of asinewave output and are more suited torun electronic equipment.• If in doubt consult your genset dealer ormanufacturer for advice.ESM2000The ESM2000 electrical Supply Module is a240 volt ac and 12 volt dc power controlunit. It provides all the necessary featuresfor control of the electrics in a caravan. Theunit provides the following features:Mains 240v ac - MAINS MODULEwithEARTH LEAKAGE PROTECTIONOVERCURRENT PROTECTION (RCD)REVERSE POLARITY INDICATION12 volt dc - FULLY AUTOMATICTRANSFORMER/CHARGERwith OVERCURRENT PROTECTIONSHORT CIRCUIT PROTECTION- SWITCH & FUSE MODULEwith BATTERY CHANGEOVER SWITCHCHARGER ON/OFF SWITCH8 FUSED DC OUTPUT CIRCUITSUNIT DESCRIPTIONMains ModuleThe ESM2000 is designed to operate on amains supply of 207-253 volts ac (making itideal for use with low continental voltages).The 40 amp RCD (Residual Current Device)gives protection against earth faults and alsoacts as the main switch. The mains modulealso has three MCR's (Miniature CircuitBreakers) which are basically resetablemains fuses, to protect against overcurrent.Allocation of the MCB's is as follows:MCB1 - SOCKETS/FAN MASTER (if fitted)MCB2 - CASCADE/LIGHTS (if fitted)MCB3 - FRIDGE/CHARGERUsing a generatorWhen using a generator in conjunction withthe ESM2000 the following must beobserved, failure to do so may result indamage to the unit:
