Electrical 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 installation.
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 com-
ponents 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!

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.

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.
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 caravan-
side (EN 1648-1).
