Safety Circuit Breaker: Service Precautions
Pyrotechnic Battery Isolator Safety Precautions
CAUTION!
• Vehicles with battery in luggage compartment are equipped with a battery isolator to increase crash safety. In the event of a collision, the airbag control module triggers a separation, which disrupts the power supply wiring to the starter. The battery cut-off takes place pyrotechnically through a very small explosive charge. To prevent accidentally triggering a separation when working on the battery or battery cut-off, you must first disconnect negative battery terminal, refer to => [ Battery, Disconnecting and Connecting ] Battery, Disconnecting and Connecting.
• Observe notes for disposal of battery isolator units, refer to => [ Pyrotechnic Battery Isolator Disposal ] Procedures.
CAUTION!
• Testing, assembly, and repairs may only be performed by trained personnel.
• Battery Ground (GND) strap must be disconnected before performing any work on the battery isolation system.
• Technician(s) must discharge themselves electrostatically before touching the battery isolator. This is accomplished by, for example, touching grounded metal such as water pipes, heating pipes or metal carriers.
• Always install battery isolator units in the vehicle as soon as they are removed from the packaging
• If installation work is interrupted, IMMEDIATELY return the battery isolator unit to its original packaging.
• Battery isolator units must never be left out unattended.
• DO NOT install battery isolator units that have fallen onto a hard surface, or which have signs of damage.
• Storage and transport are subject to laws for explosive substances.
