1. Important Safety

Information

Warning!

Before installing or using CX series power converter,

you need to read following safety information carefully.

1-1. General Safety Precautions

1-1-1. For indoor use, do not expose CX-Series Battery Charger

to water, mist, snow, or dust. To reduce the risk of fire, do

not cover or obstruct the ventilation enclosure.

1-1-2. To avoid the risk of fire and electric shocks, make sure

that existing wiring is in good electrical condition and not

undersized.

1-1-3. Do not charge non-rechargeable batteries.

1-1-4. Disconnect the AC Grid before making or breaking the

connections to the battery.

1-1-5. Only the AC cord with IEC socket is allowed to plug to the

battery charger.

1-1-6. Never charge a frozen battery.

1-1-7. If the AC cord is damaged do not attempt to use. It must

be replaced or repaired by a qualified person.

1-1-8. Corrosive substances may escape from the battery

during charging and damage delicate surfaces. Please

store and charge in a suitable area.

EN

1-2. Battery Precautions

1-2-1. If battery acid contacts your skin or clothing, wash it out

with soap and water immediately.

1-2-2. If battery acid contacts your eyes, wash it out with cold

running water for at least 20 minutes and get medical

attention immediately.

1-2-3. Never smoke or make a spark or flame in the vicinity of

the battery.

1-2-4. Do not drop metals on the battery.

The resulting sparks or short-circuits on the battery or

other electrical parts may cause an explosion.

1-2-5. Remove personal metal items such as rings, bracelets,

necklaces, and watches when operating with lead-acid

batteries. It may cause short circuit and very high

temperature, which can melt metal items.

2-1. Battery Charging Curve

Figure 1. CX series Battery Charging Curve

2-1-1. Bulk Stage (Constant Current)

At the beginning of the charging process, the flat battery is

charged at constant current (maximum charge current) until the

battery voltage reaches the set charging voltage (Refer to 3-2

charging mode setting).

2-1-2. Absorption Stage (Constant Voltage)

The absorption charging duration will depend on the battery

status.

Before moving to absorption stage, charger will wait for two

minutes then charging at constant voltage until the battery is fully

charged.

Once the battery is fully charged or the charging current is below

6.25% of the rated charging current for 15 minutes, then the

absorption stage ends.

2-1-3. Float Stage

After absorption stage, the battery charger switches to float

stage, maintains the battery at 100% charge without

overcharging or damaging the battery. This means the charger

can be left connected to the battery continuously.

2-1-4. Recondition stage

Every 14 days, the battery charger switches back to Bulk stage

for 85 minutes in order to revive the battery. This prevents any

fatigue symptoms such as sulphation.
