Event 901

Qualified person

Event message:

  • PE connection missing

  • Check connection

Explanation:

Starting from firmware version 2.5.29.R, the parameter Ground connection monitoring is available. This function monitors whether the grounding conductor is correctly connected to the grid when it is enabled (in the standard case).

Corrective measures:

  • Ensure that the grounding conductor is correctly connected.

  • If the SMA eCharger is connected to a utility grid where the grounding conductor is missing (e.g., a delta IT system), set the parameter to [No].

  • After setting the parameter, restart the SMA eCharger.
