[2] SAFEGUARDS AGAINST BAD CONNECTIONS
The charger will remain in standby mode in case of short-circuit, battery
voltage below 7,5V, open circuit, or reverse polarity connection of the
output terminals. In case of reverse polarity connection the LED (!) will
signal the error.
[3] TEMPERATURE PROTECTION
If the charger becomes too hot for any reason during charging, the output
power will be reduced automatically to protect itself against any damage.
This may lengthen the charging cycle.
4. Operating Instructions
Please read these instructions carefully before using the charger.
[1] This charger has been designed for use on a normal 220V - 240V
50/60Hz mains voltage. It can be used to charge a variety of 6V and 12V
lead acid batteries, such as WET, GEL and AGM, which are widely used
for cars, motorcycles and other vehicles. Battery capacities range from
1,2Ah to 30Ah.
[2] This charger is suitable to charge lead-acid batteries only.
[3] Clean the battery terminals. Take care to prevent eye or skin-contact
with any corrosion.
[4] Make sure that the area around the battery is well ventilated during
the charging process. When the battery is being charged some fluid
bubbling may occur: this is generated by gases during the charging cycle.
