Electrical system
Bearing in mind the cooling of the connecting cable, the
cable must not be rolled up on a drum when it is connected
to the mains. The caravan must be positioned as close to
the mains connection as possible in order to reduce the
length of the lead. If you feel there is a risk of the lead
being damaged due to mechanical causes, it should be
suitably protected.
The arrangement between the parking place mains output
and the caravan must comprise the following components:
- A plug with a protective conductor connector and in
a version intended for industrial use.
- A type A07BB or H07RN-F connecting cable or
similar cable of the following version:
Minimum area: 2.5 mm
2
Protective conductor: Green/yellow
Neutral conductor: Light blue
Electrical system 230 V
The caravans’ 230 V system is designed in accordance
with ELSÄK-FS 2004:1. The maximum power that can
be connected is 3 kW (3150 W).
The caravans have a 230 V central electrical unit equipped
with a 25 A earth leakage circuit breaker, which provides
protection against any earth faults and which also works as a
master switch for the 230 V installation. The earth leakage
circuit breaker also has a button for testing the circuit
breaker’s function. There are also two 16 A and two 10 A
miniature circuit breakers that are tripped in the event of
an overload or a short-circuit. If the earth leakage circuit
breaker or the miniature circuit breakers have tripped, the
fault must first be located. In all cases apart from an over-
load, the fault must be repaired by an authorised engineer
before returning the reset button to the original position.
Some caravans have a load guard installed in the central
electrical unit. Read more about this in ”Load guard”
on page 31.
The central electrical unit is located on the reverse of the
mains input in one of the caravan’s wardrobes.
The mains input for the caravan is supplied with a locka-
ble cover. When connecting the caravan to 230 V, first
connect the cable to the caravan’ input and then to the
parking place output.
When the caravan is no longer to be connected to 230 V,
the connector in the caravan’s mains input must always
be disconnected.
To avoid damage and faults arising in the 230 V system,
the system must be inspected regularly.
The connecting cable must not be rolled up
on e.g. a drum when the caravan is connected
to the mains.
∆
Always disconnect the connector from the
230 V input when the caravan is not to be
connected to 230 V.
∆
Repairs, conversions or additions to electrical
systems must be carried out by an authorised
expert, due to the considerable risk of perso-
nal injury or material damage in the event of
incorrect installation.
