2.4 Operation while driving
The EC176 system is designed to shutdown parts of the system whilst the vehicle engine is running.
This is to meet Electro Magnetic Compatibility (EMC) regulations and to ensure the safe operation of
the system.
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.
