Voltage
Alternating voltages (AC) of U >= 30 V and/or direct voltages (DC) of U >= 60 V occur on the following systems and component parts in vehicles and bodies:
On the high-voltage on-board electrical system and high-voltage component parts of HYBRID vehicles, electric vehicles, and fuel cell vehicles
On the lithium-ion battery of HYBRID vehicles, electric vehicles, and fuel cell vehicles
On fuel cells
On solenoid and piezo injectors and their control units and supply lines of gasoline and diesel engines
On spark plugs, ignition coils, their control units, and supply lines of the ignition system on gasoline and natural gas engines
On electrical ballasts, xenon bulbs, and their supply lines of xenon headlamps
On the MAGIC SKY CONTROL, DC/AC converters, and their supply lines
On voltage converters from 12 or 24 V to 230 or 110 V
On spark generators and electrodes, and their supply lines of stationary heaters
On systems that are supplied with alternating voltages (AC) of U >= 30 V and/or direct voltages (DC) of U >= 60 V via engine-driven alternators or via external connections.
On DC generators with a defective rectifier diode.
On illuminated door sill moldings, DC/AC converters, and their supply lines
Potential risks caused by alternating voltages (AC) of U >= 30 V and/or direct voltages (DC) of U >= 60 V
The flow of electric current through the body can lead to involuntary muscle contractions, heart rhythm disturbances, fibrillation of the heart, cardiac arrest, respiratory arrest, burns, or other cellular damage. The severity of the injury depends on the current strength, current type, the frequency of the current, the exposure time, and the route through the human body.
Exposure to arcs can result in first- to fourth- degree burns, "flash burns" of the eyes due to intense UV light (similar to when welding), blast trauma and injuries due to moving parts.
Secondary accidents occur as a result of startle responses that are caused by contact with voltages or electric arcs. Secondary accidents include, for example, falling from a raised workstation or a person's head making contact with an engine hood.
Each of these harmful effects can cause serious human injury or death.
Effects can occur up to 24 hours after the time of the accident. Therefore, it is essential to have a medical examination immediately after an accident involving alternating voltages (AC) of U 30 V and/or direct voltages (DC) of U 60 V.
Safety precautions/instructions
People who have electronic implants (e.g. cardiac pacemakers) must not perform work on component parts and systems with alternating voltages (AC) of U 30 V and/or direct voltages (DC) of U 60 V.
For work on component parts and systems with alternating voltages (AC) of U 30 and/or direct voltages (DC) of U 60 V, the necessary safety precautions according to the country-specific directives and legislation must be taken with the corresponding qualification measures/briefings in accordance with the respective documentation concerning the topic in the WIS, Xentry TIPS, EVA, and, if applicable, country-specific sources before starting work and during work.
Information as to which safety precautions for work on component parts and systems with alternating voltages (AC) of U 30 and/or direct voltages (DC) of U 60 V or which personal protective equipment (PPE) is required can be found in the respective documentation concerning the topic in the WIS, Xentry TIPS, EVA and, if applicable, country-specific sources before starting work.
Only tools that have been tested and have the corresponding approval may be used for work on component parts and systems with alternating voltages (AC) of U 30 V and/or direct voltages (DC) of U 60 V.
No damaged or defective live component parts and lines and no non-insulated electrical connections and lines may be installed on component parts and systems with alternating voltages (AC) of U 30 V and/or direct voltages (DC) of U 60 V.
