Volkswagen Golf Mk7 Service & Repair Manual: Safety precautions when working on high-voltage system

Danger to life from high voltage — this page covers the critical precaution for e-Golf/GTE HVAC work: anyone with a life-preserving or other electronic medical device must take specific additional care around the high-voltage system.

Danger to life due to high voltage
The high-voltage system is under high voltage. There is a risk of severe or fatal injury due to electric shock.
–  Persons with life-preserving or other electronic medical devices in or on their body must not perform any work on the high-voltage system. Such medical devices include internal analgesic 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 engine start

–  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 connectors may result in damage to their insulation.
–  Never support yourself on high-voltage cables or high-voltage connectors.
–  Never support any of your tools on high-voltage cables or high-voltage connectors.
–  Never kink or severely bend high-voltage cables.
