Safety instructions

3.1

Mains voltages, High voltage

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 electricshock 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 precautions:
¶
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.
¶
Any cables with damaged insulation must be
replaced.
¶
Check the electrical equipment every two years
and immediately deal with any problems.
¶
Only use fuses with specified current ratings.
¶
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.
Intervention 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.
¶
Carry out all work, if possible, only when ignition is
switched off and the engine is at standstill.
¶
When working with the ignition switched on and
the engine running, do not touch any live parts.
¶
Before disconnecting the (B–) cable from the
engine ground or battery (B–), switch off the
ignition.
¶
Never open the enclosures.

3.1.1 High voltages in hybrid vehicles and electric
vehicles as well as their high-voltage
components
If high-voltage components or high-voltage
wires are inexpertly handled, there is a risk
of fatal injury from high voltages and the
possible transmission of current through the
body.
¶
Deenergization is only to be performed
by a qualified electrician, a qualified
electrician for specific tasks (hybrid) or a
power systems engineer.
¶
Work on vehicles with high-voltage
components is only ever to be performed
in a safe, deenergized condition by
persons with the minimum qualification
"Trained to perform electrical work".
¶
Even after deactivating the high-voltage
vehicle electrical system, the high-voltage
battery may still be live.
¶
Operating condition cannot be established
from any running noise, as the electric
machine is silent when stationary.
¶
In gear positions "P" and "N" the engine
or electric motor may start spontaneously
depending on the charge of the high-voltage
battery.
Safety measures:
¶
Never open or damage high-voltage batteries.
¶
On accident vehicles, never touch high-voltage
components or exposed high-voltage wires before
deactivating the high-voltage vehicle electrical
system.
¶
Avoid contact with any high-voltage components
and high-voltage wires (orange sheathing) when in
operation.
¶
Secure against unauthorized renewed start-up
(e.g. by means of a padlock).
¶
After each switch off of the high-voltage system,
observe a waiting time of 5 minutes (depending
on the manufacturer's instructions). Subsequently
ascertain the absence of voltage using a suitable
testing device.
¶
Visually inspect the high-voltage components and
high-voltage wires for damage. The power systems
engineer responsible should always be immediately
notified of any irregularities, doubts or defects
found.
$
High-voltage components must never exhibit
signs of external damage.
$
The insulation of the high-voltage wiring must
be intact and undamaged.
$
Watch out for any abnormal deformation of the
high-voltage wiring.
