:Connect the battery charger in accordance with the wiring diagram on the cover. Connection to the battery
must always be made with the enclosed fuse. Use the fastening hole at the bottom of the charger and mount the
charger with a body screw or plastic strips.Route the cables straight away from the contacts (1) on the battery
charger so that the Plug-In contacts are not bent or twisted (2). Make sure the battery charger is not placed too
close to hot parts such as exhaust manifoil, turob and so on. It must also be positioned well clear of moving parts
such as pulleys, cooling fan and steering rods. To achieve voltage on both engine- and interior heater the control
inlet (marked with a clock) on the charger have a +12V signal. This is normally supplied via the control units yellow
cable. If a control unit is not mounted, this signal might be achieved from the +12V outlet on the charger. The relay
will only be activated and load voltage when both +12V control signal and 230V is attached to the charger.
The charger must be positioned with the contacts facing dOWn and is fastened by means of screws
or strips.
The electronic battery charger has the following characteristics:
• Charging current 3A at 12V.
• Advanced, battery friendly technology allows continuous operation.
• Temperature compensated charging voltage.
• Light indication during charging.
• Power distribution to engine and interior heater.
• Integrated relay for switching engine and interior heater on and off.
• Splashproof (IP 54).
The battery charger functions independently of the start timer for the car heating system. The charger switches
to maintenance mode when the battery is fully charged. It can also be used to advantage in the summer, but
the control unit must then be switched to OFF mode. The Led at the top of the charger is illuminated when the
charger is charging with full effect. It is not illuminated during maintenance mode. This means that the Led will
be illuminated when connected to 230V if the battery has been without charge for approximately 10 minutes.
Avoid charging batteries in an enclosed area, as there is a potential danger of explosion. The temperature of
the battery may not exceed +40ºC during charging. The charger contains high voltage current. Therefore do
not use a drill on it or open it. In order to prevent potentially dangerous situations involving faulty batteries, the
charger requires a back voltage of approximately 2V to start charging. It can therefore not be used as a 12V
power supply (battery eliminator).
The control voltage for the relay is 12V nominal, minimum 9V. Consumption of current is max. 70mA. The battery
charger gives a maximum of 3A at 12V and 5A at 2V. The charging voltage is 14.4V at 25ºC. The battery charger
is protected against short circuits and wrong polarity and requires 2V back voltage to start charging.
The battery charger satisfies the standards: En 60335-1; En 60335-2-29 and nEK 599. Also the EMC require-
ments: En 50081-1 and En50082-1.
