a) Polarity reversal protection

A polarity reversal protection is built into the charger. If the charger is not yet plugged into a mains outlet and a bat-
tery is connected with the poles reversed, the red LED for "Error" (Fig. 2, Pos. 9) lights up. Check the polarity of the
battery and the connection cable.

b) Error indicator

The charger constantly monitors the charging process. If a defective battery, too high or too low of a battery voltage,
too long a charging time (more than seven hours for the refreshment programme; more than forty-one hours for the
charging programme, if the trickle charging has not yet been initiated due to the battery voltage) or a short circuit is
detected, the electronics shut off the charging process. The device is then in standby mode and the "Power" LED
(Figure 2, Pos. 1) lights up.

c) 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.

d) 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.

e) housing protection type

The housing of the charger is Protection Type IP 65 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.
