2.7 Operation while driving
The EC400 / EC450 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.
