EC444/EC445/EC455 POWER CONTROL SYSTEM
• Charging when the vehicle engine is
running. When the vehicle engine is running
both the vehicle battery and the leisure
battery LED’s will flash in unison to indicate
that they are connected together and are
being charged by the vehicle.
• Tank Fill Button. For some caravans, with
the power on, press the tank fill button to
turn the external filler pump on or off. Please
ensure you switch the fill button off when the
external tank is empty to prevent damage to
the pump.
2.7 Operation while driving
The EC system is designed to shutdown parts
of the system while the engine is running.
This is to meet Electro Magnetic Compatibility
(EMC) regulations and to ensure the safe
operation of the caravan. This is indicated by
the two battery LED’s flashing together.
Please ensure the system shutdown switch
on the PSU is in the “on” (button in) position
before driving (see 2.3). This will ensure the
electronic system is active and will therefore
be able to control the charging process,
supply the refrigerator and monitor other
system circuits.

The Residual Current Device (RCD) is basically
provided to protect the user from lethal electric
shock. The RCD will turn off (trip) if the current
flowing in the live conductor does not fully
return down the neutral conductor, i.e. some
current is passing through a person down to
earth or through a faulty appliance.
To ensure the RCD is working correctly, the
test button should be operated each time the
vehicle is connected to the mains supply (see
section 2.4)
The Miniature Circuit Breakers (MCB’s) operate
in a similar way to traditional fuses and are
provided to protect the wiring installation from
overload or short circuit. If an overload occurs
the MCB will switch off the supply. If this
occurs you should investigate the cause of the
fault before switching the MCB back on.
