Battery
Charging the
battery
The optional battery requires no maintenance and has low gas emissions.
Note
If the splicer is not used for a long time, fully charge the battery at least every three
months.
Connect the splicer with the AC power cord to the AC supply. The charging indicator
lights up.
Note
If the charging indicator does not light up, locate the cause of the fault (section 7)!
After approx. 3 hours, the empty battery will be fully charged again. The internal charger
prevents overcharging.
You can also charge the battery via the external 12-V connection. To do this, apply a
DC voltage of 14.0 V to 14.5 V. The charging time depends on the voltage applied.
Caution
If you charge the battery using the external 12-V connection, the charging voltage must
not exceed 14.5 V.
The splicer can be used during the charging process.
Danger
During (trickle) charging, hydrogen can escape from the battery which, if ventilation is
inadequate, can result in an explosive mixture of gases being concentrated in the bat-
tery. For this reason, the venting hole (1) in the splicer must always be kept free.
