External start/
stop
The external start/stop option prevents sparking if the charging plug is disconnected during
charging. Special contacts inside the charging plug register a separation from the charging
socket. These are leading contacts in relation to the main contacts. This triggers an imme-
diate stop to charging. As a result there is no wear to the main contacts, and this arrange-
ment safeguards more effectively against an oxyhydrogen explosion.
Charging lights Suitable external lamps can be connected to the connections inside the device as illustrat-
ed in order to indicate the state of charge or operating status of the charger. Each external
lamp must have a working voltage of 13 V, and the total current drawn by all the external
lamps must not exceed 0.5 A.
