7. SAfETY dEVICES

a) Polarity reversal protection

The charger has an integral reverse polarity protection. If the charger is connected to a battery with reversed polar-
ity, the LED of error indication (Figure 2, Item 9) lights up. Check the polarity of the battery and the connection cable.

b) Anti-spark protection

The charger is still deactivated during connection to a battery. Therefore, unlike with conventional chargers, sparks
do not normally form due to a charge equalization when the charger is being connected to the battery. After the
connection, the charge state of the battery is checked first. Only after this test of the already connected battery does
the charging process start automatically.

c) overheating protection

An overheating protection is built into the charger, which reduces the charging current automatically if the tempera-
ture in the charger is too high. When the internal temperature has dropped again, the charging process continues
completely normally.

d) housing protection type

The housing of the charger is protection type IP 64 and thus serves to protect the charging electronics built into the
housing against dust and moisture. The plugs and connections do not meet this standard. The charger is therefore
approved for operation in dry, closed rooms only.
