→ Only appropriately trained and authorized persons are permitted to work on high-voltage vehicles and components.
→ Required qualification: High voltage technician or high voltage expert.
→ Observe national requirements and legislation for this work.
→ Always use insulated tools, e.g. > VAS 6883 - Insulated Tool Set when working on these components.
→ Observe general warning notes for working on the high-voltage system.

Preliminary work for measurement 7
(Power electronics)
Loosen and disconnect 3-phase line (power electronics - electric motor).
Power electronics
Connect high-voltage test adapter > VAS 6558/9-6 - High-voltage test adapter HVA 280 to the power electronics connection for the electric air-conditioning compressor. Leave the second connection open.
Measurement 7
Perform measurement 7.
Setpoint value > 550 MOhm
Evaluate measured result.
If the measured value is within the tolerance range, continue with measurement 8
If the measured value is outside of the tolerance range, replace power electronics.
After replacing the power electronics, repeat measurement 5.
