Safety Precautions When Working On High-Voltage System

There is a risk of fatal injury due to electric and magnetic fields

The high voltage system emits electric and magnetic fields. Fatal or serious bodily injuries are possible if active implants (for example, pacemaker, insulin pumps) start malfunctioning.

-- Individuals with active implants cannot perform any procedures on high-voltage systems.

There is a risk of injury from unintended engine start.

On electric and hybrid vehicles an active ready mode is difficult to identify. Risk of pinching and pulling parts of the body.

-- Switch the ignition off.

-- Place the ignition key outside of the vehicle interior.

Risk of damaging the high-voltage cables.

Misuse can damage the insulation of high-voltage cables or high-voltage connectors.

-- Never support on the high-voltage cables and the high-voltage connectors.

-- Never support tools on the high-voltage cables and the high-voltage connectors.

-- Never sharply bend or kink the high-voltage cables.

-- Pay attention to the coding when connecting the high-voltage connectors.

Hazard of life due to high operating voltage.

The high-voltage system is under high voltage. Electrocution by direct contact or electric arc can cause fatal or serious personal injury if high-voltage components and high-voltage cables are damaged.

-- Perform a visual inspection of the high-voltage components and the high-voltage cables.

-- Never use cutting, shaping, or sharp-edged tools near high-voltage components and high-voltage cables.

-- Never weld, solder, use thermal bonding or hot air near high-voltage components and high-voltage cables.
