To avoid the danger of fire and electric
shock,theymayalsonotbeusedasDC
power supplies.
• Thechargermustonlybeconnectedto
an appropriate power socket with an earth
connection.
• Youshouldhavewaterandsoapywater
available when using the accumulator.
The accumulator contains corrosive
substances that are dangerous to the skin
and especially the eyes. If you should
accidentally come into contact with these
substances, immediately rinse the affected
region with water and seek medical help.
• Theaccumulatorstoresagreatdealof
energy. The plus and minus terminals
should not be shorted with metal objects or
this may cause a short circuit resulting in
personal injury or fire.
• Non-rechargeablebatteriesmaynotbe
charged.
• Firstconnectthebatteryterminalthatisnot
connected to the vehicle chassis. The other
connection is then made to the vehicle
chassis, away from the battery and fuel
lines. Only then should the battery charger
be connected to the mains power supply.
The apparatus needs to be switched off
completely in the case of:
• Malfunctioningordamagetothemainsplug
or mains cable.
• Smokeorstenchfromscorchedinsulation.
Alwayswearsafetyglassesandold
clothes during working with the battery,
because battery acid is a biting
product!
3. INSTALLATION
Before putting the battery charger into operation
thefollowingstepsneedtobetaken(Fig.1):
• Ifthebatteryisstillconnected,itneedsto
be disconnected,
• firstthenegativeterminal(A);
• thenthepositiveterminal(B)!
It is advisable to remove the battery from
the vehicle before charging it.
• Checkthelevelofthebatteryacid.Forthis
purpose remove the battery stoppers first,
then check the acid level and, if necessary,
fillupwithdistilledwater(availablefromthe
chemists’).Theleveloftheelectriccharge
can be checked with a hydrometer.
• Cleantheconnectionsandtheterminals.
This can be done with a steel wire brush or
with sandpaper.
• Connectthepositiveclampofthecharger
(red)tothepositiveterminal(+)ofthe
battery. Then connect the negative clamp of
thecharger(black)tothenegativeterminal
(-)ofthebattery.Checkiftheclampsofthe
charger are firmly connected to the battery.
• Thefollowingstepsneedtobetakenwith
the help of the information of the charge
control display.
• Thechargermustnotbeplacedontopof
the accumulator or vice-versa. This is both
illegal and unsafe
• Iftheaccumulatortemperaturerisesabove
40ºCthenthechargingcurrentshould
be reduced, and if the temperature rises
above45ºCthenyoushouldstopcharging
and only resume charging when the
temperature has dropped.
• Nowplugthepowerplugintothemains
socketandsettheswitchto“Charge”.
When charging, you should keep an eye
on the current meter to check that the
indicatorisworkingproperly.(Caution!(1)
Our chargers are only suitable for those
accumulators having a residual voltage
above 2 V. No current flows into batteries
havingaresidualvoltagebelow2V(2).
The current meter only provides a general
indicationandnotanexactmeasurement).
• Whenthe“Full”lampilluminatesduring
charging, you should check that the battery
electrolyte has reached a specific gravity of
1.28. If not, then you can continue charging,
andifso,thenchargingisfinished.You
shouldthensetthe“Voltage”switchto“Off”.
Then remove the mains power plug and the
two clips from the plus and minus terminals
oftheaccumulator.(Whenchargingthe
battery while still in the vehicle, you should
first remove the clip connected to the
chassis.)
