E) CONNECTION TO BATTERY
We advise the use of bipolar standard connectors which do not allow reverse polarity on battery.
Check cable connection in the connector contacts.
This operation has to be performed by skilled personnel only.
F) DESCRIPTION OF THE CHARGE CHARACTERISTICS
CHARGING CURVE Wa
The charging curve of a battery charger 'Wa' corresponds to the curve defined by DIN 41772 and is
characterized by the following trends:
• As the battery voltage the charge current decreases as described by Statement;
• The rated charging current is dimensioned as a C5 / 6
• Once the voltage gas development of 2.40 V / cell., the electronic control evaluates the capacity of the
battery and defines how many Ah have to be loaded into the final charge to get the desired charging factor.
• Charging stops when it reaches a charging factor of about 118% (adjustable);
• Control with safety timer to 11 hours on the first charging.
• Charging time expected 9.0 ÷ 12.0 hours max depending on battery capacity (equalizing charge excluded).
CHARGING CURVE WOWa
The charge curve of a battery charger 'WoWa' matches a curve "fast" (within 8 hours) and is characterized by
the following trends:

As the battery voltage increases, the charging current decreases as described by the Standard;

The first phase of charge (Wo) is a higher current (C : 5) compared to the characteristic Wa;

Once the gas tension development of 2,40V/cell., the battery is charged by switching the transformer on
the curve (Wa) lower.

This process goes on until a charge factor between 115% and 118% is reached ; Afterwards the battery
charger will automatically switch off.
CHARGING CURVE WOWp
The charging characteristics of a Pulse battery charger corresponds to a modified Wa characteristics and is
characterized by the following trend :

Battery voltage increases while charging current decreases, as laid down in DIN 41774 (Wa charging
characteristics).

After reaching gassing point (2,4V/cell), battery is charged with a Wp characteristics (higher) alternating
with a Wa characteristics (lower).

This process goes on until a charge factor of approx. 110% is reached ; Afterwards the battery charger will
automatically switch off.
G) DESCRIPTION OF A CYCLE OF CHARGE
- Connect battery charger to battery and mains supply.
- Since the charger is equipped with autostart, the charging process will automatically start a few seconds
after connection (provided that the charger has detected mains presence).
- The charging process stops automatically when the battery has been fully charged.
WARNING ! Never disconnect the battery connector while charging !
If you need to stop charging, switch-off the charger by pressing the ON/OFF push-button
- Battery is charged with a method compensating for the ampere-hours missing in the battery (This means
that mains fluctuations or changes are completely compensated).
- The charging process begins only if battery voltage falls within the range foreseen for that charger.
- The charging process automatically begins after connection to battery.
- If charging time exceeds the security timer (7 hours for a WOWa charger and 11h for a Pulse charger)
before reaching gassing voltage, the charging process is automatically interrupted by a safety timer.
