Electrical installation
Electrical installation may only be carried out by qualified personnel.
The connection cables must be laid in such a way that they do not come in
contact with hot components of the unit/burner or with sharp edges.
The electrical installation must comply with national regulations (EN
60335-1 for Europe).
Power line connection
The power must be supplied via a properly earthed socket outlet or hard-
wired connection.
Where a socket outlet is used for the mains connection lead, the outlet
must be freely accessible.
It is advisable to run the incoming supply through an on-board fuse or automatic
circuit breaker.
The power cable must be laid in such a way that it does not come in contact with hot
components of the unit/burner or with sharp edges.
If the connection cable is damaged it must be replaced by the Customer Service
at Dometic, or by respectively qualified personnel, in order to prevent any
hazads.
12V and “D+” connections
The 12V connection is illustrated in the accompanying diagram.
The (12V+) and (-) connections have to be connected to
the auxilliary battery.
12V supply must not be connected to a voltage controller or
similar device as the AES itself monitors the DC voltage.
Do not use the chassis for the (-) return lead.
12V+ should be permanently attached, and must not be cut-out when the vehicle
ignition key is turned off.
All connections should be srewed or soldered in order the minimise voltage drop at
the connection points.
The (+) supply line must be fitted with a 20A fuse.
Terminal D+ (Alternator) must be connected to the corresponding outlet
terminal on the vehicles electrical system.
Cable cross-section
The D+ (Alternator) is a signal cable therefore 1-1,5mm2 is sufficient.
To guarantee trouble-free operation of the appliance, the 12V (+) and (-) connection
should be effected using
6mm
2
cord.
Please consult a spoecialist, if you are not familiar with the 12V electrical
system in your Motorhome.
