SmartROC D65 Tier 4 Final 2 General

Explosive gas is formed in the battery during charging. A short circuit, naked flame or spark
in the vicinity of the battery could cause a serious explosion. Ensure good ventilation. Al-
ways turn off the charge current before disconnecting the clips. If the density has not risen
noticeably despite a number of hours of recharging, the battery is probable expended.
Rapid charging, when carried out correctly, will not damage the battery. However, it should
not be undertaken too often and is not recommended for old batteries.
Repeated discharging for long periods, especially with low current such as leaving the
lights on while the engine is stationary, will impair the service life of the battery. Dischar-
ging with high current is not normally harmful. The battery must be left to rest between start
attempts, however.
Since the drill rig's 24V electrical system is powered by two 12V batteries in series, the fol-
lowing points should be observed:
n The batteries must have the same capacity (Ah).
n The batteries must be the same age. This is because the charging current required to
bring a battery up to a certain voltage changes with age.
n The batteries must not be loaded unevenly.
n Series coupling maintains the same capacity but increases the voltage (double). When
2 x 12V 60Ah batteries are connected in series, the voltage will be 24V but the capa-
city remains at 60Ah.
n Ensure that the correct voltage is used before connecting a battery charger. Use a 24V
charger when recharging both batteries and a 12V charger when charging each bat-
tery individually.
Proceed as follows (24V charger)
Before charging
1.
Inactivate battery isolation switch S300.
2.
Detach the cable between chassis ground and the negative cable on the battery G1B.
3.
Connect the positive battery charger cable to the positive terminal on G1A.
4.
Connect the negative charger cable to the negative terminal on G1B.
5.
Start the battery charger.
After charging
1.
Turn off the battery charger
2.
Detach the battery charger's negative lead from the negative terminal on G1B.
3.
Detach the battery charger's positive lead from the positive terminal on G1A.
4.
Connect the cable between chassis ground and the negative terminal on G1B.
5.
Activate battery isolation switch S300.
Proceed as follows (12V charger)
Before charging
1.
Turn off the battery isolation switch S300.
