TO START THE CHARGING PROCESS
Establish a safe connection between the battery and the charger first. Then plug the
mains connector. This sequence must always be followed in this order. When
removing the connection, remove the mains plug from the mains first before
disconnecting the battery circuit.
After connecting the battery, the red LED error LED) flashes several times and then
remains OFF. When the charging process starts, the yellow LED comes ON also a
click from the relay in the charger can be heard and the cooling fan starts to
operate).
Indic tion LED p ttern:
Yellow LED ON: Main charge phase with maximum charging current
Yellow LED fl shes slowly: Constant voltage charging phase about 80% charged)
Green LED ON: Battery 100% charged
NOTE: Function of the yellow LED charging is programmable together with other
charging parameters. Description above shows the usual setting.
If local standards or regulations allow it, the battery may be permanently connected
to the charger. The cooling fan is temperature controlled and operates at different
speeds. The charging time depends on the battery capacity. If the battery has been
partly discharged, the charging process will finish sooner.
IMPORTANT SAFETY INSTRUCTIONS
Read the manual thoroughly.
The charger must be used with the original cables only. Do not change, shorten,
extend or short circuit the cables.
Remove the mains plug from the mains first before braking the battery circuit.
Only rechargeable batteries can be used. Do not connect any non-rechargeable
batteries like dry-cell batteries) to the charger.
The charger may be used for the correct battery type only.
Do not install the charger inside motor-homes, campers or caravans.
Check the charger for cable, housing and connector damages before use. Do not
operate the charger when damaged. There are no user serviceable parts inside.
Do not expose the charger to rain, moisture, direct sunlight or dust.
Always disconnect mains after charging and generally when the device is not in
use. During the trickle charge the charger remains attached to the mains.
Always disconnect the mains during a thunderstorm.
ERRORS
No LED lights or flashes after the
charger has been connected to the
mains
1. Check if the battery is properly connected
2. Check the mains
3. Contact your after-sales service point
