Safety instructions

2.1

Risk of electric shocks

2.1.1

Low voltages, high voltages

Hazardous voltages occur in both the lighting
system and the electrical system of a motor
vehicle. If contact is made with live parts
(e.g. with the ignition coil), there is a risk of
electric shock from flashover voltages caused
by damaged insulation (e.g. ignition cables
which have been attacked by martens). These
apply to the secondary and primary sides of
the ignition system, the wiring harness with
connectors, lighting system (Litronic) as well
as connection to the vehicle.
Safety measures:
¶
Only connect to a properly grounded outlet.
¶
Only the enclosed or a tested power supply cable is
to be used.
¶
All extension cables must be fitted with shock-proof
contacts.
¶
Do not exceed the voltage limits as specified on the
connection cables.
¶
Any cables with damaged insulation must be re-
placed.
¶
Before connecting it to the vehicle, first connect the
product to the lighting mains and switch on.
¶
Before switching on the ignition connect the (B-)
cable to engine ground or the battery (B–) terminal.
¶
Always switch off the ignition before performing any
work on the electrical system of the vehicle. Inter-
vention includes, for instance, connection to the
vehicle, replacement of ignition system components,
removal of equipment (e. g. alternators), connection
of equipment to a test bench.
¶
Wherever possible, tests and settings should always
be caried out with the ignition switched off and the
engine stationary.
¶
If tests or settings are carried out with the ignition
switched on or the engine running, care must be
taken not to touch any live parts. This applies to all
connection cables and leads as well as to connec-
tions of equipment to test benches.
¶
Test connections must always be made using suit-
able connectors (e.g. Bosch testing cable set or
vehicle-specific adapter cables).
¶
Make sure that all test connections are properly
plugged in and secure.
¶
Before disconnecting the (B-) cable from the engine
ground or battery (B–), switch off the ignition.
¶
Never open the enclosures.
