n The electrical installation must be in
accordance with the national regulations
of the respective countries.
n The connection cables must be routed in
a way to prevent contact with hot
components of the unit/burner or with
sharp edges.
n Changes to the internal electrical instal-
lation or the connection of other electri-
cal components (e.g. external fan) to the
internal wiring of the appliance will ren-
der the e1/ CE admittance as well as any
claims from warranty and product liabili-
ty void!
* Specialised personnel are accredited experts who are
able, by virtue of their training and knowledge, to vouch
for the correct installation.
4.9 Electrical installation
The electrical installation shall be carried
out by qualified personnel* only.
WARNING!
4.9.1 Mains connection
n 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 accessi-
ble.
n Should the connection cable be dama
ged, have it replaced by Dometic
Customer Services or by qualified per
sonnel to avoid hazards.
We recommend leading the power supply via
a board-side fuse protection.

Installation
4.9.2 Battery connection
The machine's 12V connection cable is con-
nected (observing correct polarity) to a termi-
nal strip (RMx 8xx0) or plug-in-contacts (RMx
8xx1, 8xx5). The wiring for the 12V heating
element (refer to A, B wiring diagram connec-
tions) must be direct and by the shortest pos-
sible route to the battery or electric generator.
To
protect the on-board 12 V circuit provide
the following fuses:
- RM8xxx, RMS8xxx: 15 A
- RML855x, RMSL855x: 20 A
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 12V
heating element (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)
must be permanently provided by a 12V DC
power supply to be protected by a 2A fuse.
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 caravan-
side (EN 1648-1).
