Safety measures for working on vehicles with high-voltage system
Danger to life from high voltage
The high-voltage system is under high voltage. Severe or fatal
injury from electric shock.
– Persons with life-preserving or other electronic medical devi‐
ces in or on their body must not perform any work on the high-
voltage system. Such medical devices include internal anal‐
gesic pumps, implanted defibrillators, pacemakers, insulin
pumps and hearing aids.
– The high-voltage system must be de-energised by a suitably
qualified technician.
Risk of injury due to unexpected motor start
On electric and hybrid vehicles, it can easily be missed that the
vehicle is in „ready“ mode. There is a risk of parts of the body
becoming trapped or drawn in.
– Switch off ignition.
– Always store the ignition key outside the vehicle.
Risk of damage to high-voltage cables
Improper handling of high-voltage cables or high-voltage connec‐
tors can result in damage to their insulation.
– Never support body weight on high-voltage cables or high-
voltage connectors.
– Never support any tools on high-voltage cables or high-volt‐
age connectors.
– Never kink or severely bend high-voltage cables.
– Always observe the coding when connecting high-voltage con‐
nectors.
Risk of injury from activate stationary air conditioning
On electric and hybrid vehicles with active stationary air condi‐
tioning, the stationary air conditioning could switch on uninten‐
tionally. Risk of limbs becoming trapped or drawn in by the
radiator fan starting automatically.
