3.1.3 Safety Precautions for High Voltage/Line Voltage
It is a precondition for performing high-voltage measurements that the user has knowledge of
automotive technology and is therefore aware of the sources of danger and risks in the workshop
and on motor vehicles. An additional country-specific qualification is mandatory.
Very high voltages occur in electrical systems. Due to voltage flashover on damaged components,
such as marten damage or touching live components, the risk of electric shock is likely. Voltage
flashover can occur e.g. on the primary and secondary side of the ignition system, the connection
to the vehicle, the lighting systems or the wiring harness with plug connections. Therefore regard
the following:
•
Only use power supply cables with grounding contact.
•
Only use a checked or the attached power cord.
•
Always use the original cable set.
•
Do not exceed the voltage limits indicated on the connecting cables.
•
The voltage values to be measured must be shielded extra or even twice from dangerous line
voltage. The voltage limits printed on the test leads must not be exceeded. Pay attention that
the allowed measuring range is not exceeded when measuring positive and negative voltage
at the same time.
•
Regularly check cables and adapters for damage.
•
Perform any assembly work such as the connection of the MT-HV to the vehicle or the
replacement of components only when ignition is switched off.
•
Do not touch live components when the ignition is on.
3.1.4 Safety Precautions – Chemical Burns
In case of improper use electrolyte may escape from the battery and may cause chemical burn of
eyes, respiratory system and skin. Therefore regard the following:
•
Wear personal protective equipment when working on the battery.
•
Immediately rinse acid splashes from parts of the body or clothing thoroughly with water and
consult a doctor instantly.
•
Instantly consult a doctor if you have aspirated acid vapor.
3.1.5 Safety Precautions – Risk of Injury
When working on the vehicle, there is a risk of injury through rotating parts or rolling of the
vehicle. Therefore regard the following:
•
Protect vehicle against rolling away.
•
Additionally, place the gear selector to park position in vehicles with automatic transmission.
•
Deactivate the start/stop system to avoid an inadvertent engine startup.
•
Connect the MT-HV to the vehicle only when ignition is switched off.
•
Do not reach into rotating components when engine is running.
•
Do not run cables near rotating parts.
•
Check the high-voltage parts for damage.
