2.6 Operation while driving
The EC700 system is designed to shutdown parts of the system while the engine is running. This is to
meet Electromagnetic Compatibility (EMC) regulations and to ensure the safe operation of the
motorhome.
Please ensure the system shutdown switch on the PSU is in the on (button in) position before driving
(see 2.2). 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.
Where fitted; designated 12V sockets, en-route reading lights and en-route heating will remain
operational while the engine is running.
3 System Technical Information
The following section provides further technical information relating to the electrical system. You can
also access the supporting technical manual from
3.1 Residual Current Device & Miniature Circuit Breakers
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 2.3)
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.
The following table shows the rating and circuit allocation for the three MCB’s
