Electrical System; The 230 V Ac Electrical System - Mercedes-Benz KABE Travel Master 2022 User Manual

ELECTRICAL SYSTEM

The electrical system in the KABE Travel Master is made up of three separate systems:
•

The 230 V AC electrical system.

Used for the boiler's immersion heater, the refrigerator and the battery charger.
• The living area's 12 V system.
Used for most electrical functions in the living area, e.g. lighting, water pumps and refrigerator.
• The vehicle's 12 V system. Used for running lights, starter motor and other electrical functions
relating to the vehicle and travel. See the vehicle's user manual.
THE 230 V AC ELECTRICAL SYSTEM
The 230 V AC electrical system is used for the boiler's im-
mersion heater, circulation pumps, refrigerator and battery
charger.
The highest permitted power load is 3,600 W (16 A).
The 230 V AC system is energised by connecting an
earthed power cable to the motorhome's junction box. The
power cable must be approved for outdoor use and power
loads of 3,600 W (16 A).
(Cable's cross section: at least 2.5 mm
Connect the power cable to an earthed socket.
KABE recommends power cables with an in-built residual
current device.
WARNING!
Risk of injuries.
Use a power cable that is approved for
outdoor use.
Site the cable away from all risk of damage.
Damaged cables must be replaced.
If there is a voltage drop, the motorhome's electrical equip-
ment may not function satisfactorily.
The longer the supply cable, the greater the voltage drop.
See the tables for the voltage drops with different lengths
of cable.
At camping sites, the incoming supply may be affected by
drops that bring the voltage down to as low as 180 – 190 V
(especially in winter when the loading is high).
If the power cable is kept in a reel, it must be fully un-
wound before connection. A cable on a cable reel fun-
ctions as an electrical coil. This results in heating and
power loss (voltage drop) in the reel. The cable gets very
hot when power consumption is high.
Pay attention also to ensuring that the cable is not expo-
sed to damage and that the plug is securely connected.
