4.9Electrical installation
WARNING!
The electrical installation shall be carried out by qualified personnel* only.
*Qualified personnel are accredited experts who are able, by virtue of their training and knowledge, to vouch for the correct implementation of the leakage test.
The electrical installation must be in accordance with the national regulations of the respective countries.
The connection cables must be routed in a way to prevent contact with hot compo nents of the unit/burner or with sharp edges.
Changes to the internal electrical installa− tion or the connection of other electrical components (e.g. external fan) to the internal wiring of the appliance will render the e1/ CE admittance as well as any claims from warranty and product liability void!
4.9.1 Mains connection
The power should be supplied by a pro perly grounded socket outlet or a groun− ded non−detachable connection. Where a socket outlet with mains supply is used, the outlet must be freely accessible.
Should the connection cable be damaged, have it replaced by Dometic Customer Services or by qualified personnel to avoid hazards.
We recommend leading the power supply via a
4.9.2 Battery connection
The machine's 12V connection cable is connec- ted (observing correct polarity) to a terminal strip. The wiring for the heating element (refer to A, B wiring diagram connections; connection cable white/red) must be direct and by the shor- test possible route to the battery or electric generator.

CAUTION!
If the appliance is installed in a caravan the respective leads for the 12V+ and 12V- connections A/B and C/D must not be connected to each other on the
Provide a 16 A fuse to protect on-board 12 V circuit.
In order to ensure that the 12V power supply is shut off when stopping the engine (otherwise the battery would discharge within a few hours), perform the power supply to the heating ele- ment (cf. page 30, connection A/B in wiring dia- gram) in a way to have the 12V supply only live while the vehicle ignition is switched on.
The connection C/D (interior light, electronics, cable black / violet) must be permanently provi- ded by a 12V DC power supply to be protected by a 2A fuse.
