Operating  Procedure

Selective  Switches

a. Before charging the battery installed in a vehicle, please turn off all the electrical equipment including lights and 
    other accessories connected to the vehicle.
b. Please identify the polarity of the battery: the POSITIVE (POS, P, +) and NEGATIVE (NEG, N, –) pole.
c. Please inspect which battery pole is grounded (connected to the vehicle chassis). The negative pole is usually 
    (but not always) grounded.
d. For charging a battery installed in a vehicle, please connect the POSITIVE (RED) and NEGATIVE (BLACK) clip 
    of the charger to the POSITIVE (+) and NEGATIVE (-) pole (or the vehicle chassis) of the battery respectively. 
    Please ensure the NEGATIVE (BLACK) clip should not be located near the fuel-pipe, carburetor and fuel 
    tubess Sheet-metal parts should be free from any clip.
e. For charging the battery which is not installed in a vehicle, please connect the RED and BLACK clip to the 
    POSITIVE and NEGATIVE pole respectively.
f.  After plugging the AC power cord of the charger into the AC outlet, all charge-indicating LEDs 
    scanned successively.
g. Press the mode button to select vehicle type. This sets the battery maximum charging current (refer to  
    specifications).

This switch selects operating modes among Snow mode (14.7V or 29.4V ) and normal mode
(14.4V or 28.8V ).
Snow mode is proposed for AGM batteries or low temperatures.
Please follow the charging instructions of battery manufacturers.

CHARGING STEPS

EXPLANATION OF CHARGING STEPS

1. Desulphation/Desulfurization:
    Desulphation/Desulfurization revives the battery via a series of current pulses dissolving sulfur from the internal
    battery poles to activate chemical reaction.
2. Diagnosis:
    The charging current is set to a relatively low level while the microcontroller is diagnosing physical 
    conditions of the battery.
3. Bulk Charging:
    This is a high current charge to minimise charge time.
4. Absorption:
    In this stage, the battery voltage is returned to its normal fully charged level and the charging
    current is gradually decaying to nil.
5. Supervision:
    The microcontroller supervises the voltage decline of the fully charged battery from its normal level to its floating  
    level.
6. Float Charging:
    The battery voltage is maintained at its floating level by the charger via supplying an intermittently minimal 
    charging current.

• Latest technology switchmode design circuitry meets safety approvals
• Spark free circuitry prevents sparks on connection and disconnection
• Low ripple current design prevents heat and gas build-up from batteries
• High efficiency (over 80%), fan-less design
• Internal temperature shielded unit keeps case cool
• Three options for charging current
• Robust design protects unit in abnormal situations.
• 6 charging steps aids and facilitates battery chemical reaction extending battery life
• Inbuilt active PFC circuitry PFC >0.95 (optional)

h. Select Snow mode for charging at 14.7 or 29.4V for AGM batteries, or where the ambient temperature is below 
    0º C.
i.  If the charging LED continually blinks, the battery is being charged. When the charging LED is permanently on, 
    then the battery is fully charged.
j.  If the fault indicator LED blinks, or is permanently on, then the battery will not accept a charge.
