Line-to-Line Voltage Out of Range (3P, 70/71, 8x25/8x26)

Three phase line to line voltage above (VLL Max) or below (VLL Min) the permitted range.

Common causes

Network voltage issueWrong country code

What to check

STEP 1

Verify the country setting, then measure phase to phase voltages.

Escalate if

Correct settings and healthy grid but fault persists
