External start/
stop
The external start/stop option prevents sparking if the charging plug is discon-
nected during charging. Special contacts inside the charging plug register a sep-
aration from the charging socket. These are leading contacts in relation to the
main contacts. This triggers an immediate stop to charging. As a result there is no
wear to the main contacts, and this arrangement safeguards more effectively
against an oxyhydrogen explosion.
Charging lights Suitable external lamps can be connected to the connections inside the device as
illustrated in order to indicate the state of charge or operating status of the char-
ger. Each external lamp must have a working voltage of 13 V, and the total cur-
rent drawn by all the external lamps must not exceed 0.5 A.
