2.7 Operation while driving
The EC400 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 or motorhome. 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.
On motorhomes if / when fitted,
designated 12v sockets, en-route reading
lights and en-route heating will remain
operational while the engine is running.

The following section provides further
technical information relating to the
electrical system. You can also access the

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.
