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.
