• Position the battery charger as far away from the
battery as the leads will allow. The battery charger
contains switches that may create a spark.
• Do not set a battery on top of the charger.
• Explosive gases may collect near the ground. Locate
the battery charger as high as possible above ground
level.
• Do not use power tools in the charging area.
• Do not smoke or have a naked flame in the charging
area.
• Follow the instructions for connecting and
disconnecting the battery charger leads or battery
terminals.
Warning! A marine (boat) battery must be removed
and charged on shore. To charge it on board requires
equipment specially designed for marine use. This
appliance is NOT designed for such use.
Vehicles may have electrical and electronic systems
(e.g. engine management systems, mobile phones)
that may be damaged if subjected to high starting
voltages and voltage peaks. Before connecting the
appliance to the vehicle, read the vehicle's owner's
manual to confirm that external charging is allowed.
• Follow these instructions and those published by the
battery manufacturer and vehicle manufacturer.
• Only connect and disconnect the dc output clamps
after removing the supply cord from the electric
socket. Never allow clamps to touch each other.
• Check the polarity of the vehicle battery terminals
before connecting the appliance. Always disconnect
the negative (black) cable first: followed by the
positive (red) cable.
When charging a battery installed in the circuit follow
the manufacturers instructions for accessing the
battery and the following:
• Do not charge the battery while the engine is
operating.
• Be aware that engine components e.g. the coolant
fan may start automatically. Keep hands and body
away from engine components and position the
battery charger and cables to prevent contact.
• Make sure that the battery charger and the cables
are located to prevent damage from closure of doors
and engine compartment covers.
• Make sure that the connections can be made without
touching the metal body or components adjacent to
the battery.
• When using this appliance in proximity to the
vehicle's battery and engine, stand the appliance on
a flat, stable surface and be sure to keep all clamps,
cords, clothing and body parts away from moving
parts of the vehicle.

• If it is necessary to remove the battery from the
vehicle to charge or to clean the terminals, make
sure that all accessories in the vehicle are switched
off, so as not to cause a spark.
• To reduce the risk of electric shock, disconnect the
appliance from any power source before attempting
maintenance or cleaning.
CONNECTING THE BATTERY
CHARGER
When all the preparations for charging and personal
safety have been completed, proceed as follows:
• For most automotive and similar applications the
battery charger may be connected to the battery
while it is connected to the dc circuit. Follow the
instructions given in "Charging a battery installed in
the circuit".
• If the battery must be disconnected from the circuit
before charging, follow the instructions given in
"Charging a battery disconnected from the circuit".
Charging a battery installed in the
circuit
Warning! Incorrect connection, battery short circuit,
location of battery and location of the battery charger
may create a hazard. Make sure that adequate
preparation has been made before proceeding.
Warning! If the battery posts cannot be accessed or
the battery charger clamps will contact the bodywork
or components adjacent to the battery, the battery
must be removed before charging. Follow the
manufacturer's instructions to remove the battery.
• Check the polarity of the battery posts. A positive
(POS, P, +) battery post usually has a larger diameter
than the negative (NEG, N, –) battery post.
• Follow the manufacturers' instructions to remove any
insulating covers from the battery posts.
• Connect the positive (red) clamp from the battery
charger to the positive (POS, P, +) post of the
battery.
• Connect the negative (black) clamp from the battery
charger to the negative (NEG, N, –) post of the
battery or to the chassis.
When disconnecting the battery charger from the
battery, always:
• Unplug the battery charger.
• Remove the negative (black) clamp first.
• Remove the positive (red) clamp last.
• Refit any insulating covers to the battery posts.

may create a hazard. Make sure that adequate
preparation has been made before proceeding.
• If the battery is not already removed from the circuit,
follow the manufacturers' instructions to remove the
battery before charging.
• Check the polarity of the battery posts. A positive
(POS,P, +) battery post usually has a larger diameter
than the negative (NEG, N, –) battery post.
• Connect the positive (red) clamp from the battery
charger to the positive (POS, P, +) post of the
battery.
• Connect the negative (black) clamp from the battery
charger to the negative (NEG, N, –) post of the
battery.
When disconnecting the battery charger from the
battery, always:
• Unplug the battery charger.
• Remove the negative (black) clamp first.
• Remove the positive (red) clamp last.
• Refit any insulating covers to the battery posts.
USE
Charging the battery
1. Plug the battery charger's power cord into a
mains Vac outlet. The LCD screen will display the
following (the clamp icon will flash, and the empty
battery icon and the gauge without the pointer will
light):
2. The charger's battery clamps are color-coded. Red
is positive; black is negative. Connect the battery
clamps correctly to the corresponding connectors
on the battery posts. Follow the steps outlined
in the appropriate section ("Charging a battery
installed in the circuit" or "Charging a battery
disconnected from the circuit").
Notes: If the clamps are correctly connected
with regard to polarity and the unit is properly
connected to the mains Vac outlet, the unit will be
in Standby mode and the LCD screen will display
the following (the clamp icons, arrow icons, the
battery icon and the gauge without the pointer
light solid):
If the clamps are INCORRECTLY connected with
regard to polarity, the LCD screen will display the
following (the "+" and "–" inside the battery icon
and the fault icon will flash; and the clamp icons,
the battery icon and the gauge without the pointer
light solid) and a warning will sound until the
clamps are disconnected:
Unplug the charger; then remove the clamps.
Reconnect the clamps properly.
3. When the unit is properly connected, press the
battery charge button on the control panel. The
LCD screen will display the following:
The digital display shows the output current that
is charging the battery. The gauge indicates the
charge status of the battery. The clamp icons and
the battery icon light solid; the bars on the battery
icon will change from empty to solid (bottom
to top) and the arrow icons will gradually and
repeatedly move downward to the battery icon.
Notes: The " " icon will appear at the top right
of the gauge section if the surrounding ambient
temperature is higher than approximate 40°C. The
" " icon will appear at the top left of the gauge
section if the surrounding ambient temperature is
lower than 0°C. This is not a fault code, but
indicates that the unit's temperature compensation
feature is operating.
The charging process will start automatically
approximately one minute after the unit is
properly connected.
IMPORTANT: If the unit is overheated, the LCD
screen will display the following (the overheat
alarm icon, fault icon and the battery icon will
flash; and the clamp icons, arrow icons and the
gauge without the pointer will light):
Disconnect the charger and allow the charger
to cool for several minutes. Make sure there
