c1 drafted · lead UNO-DM-6.0-TL-PLUS-US Product Manual RevA

reports

c2 drafted · lead DC overvoltage

Some manuals label the input overvoltage as AC; the input voltage measurement points to the DC side

has_event_class

c3 drafted · lead Warning (device continues, a condition is flagged)

review note: support check: partial - Power limitation with continued operation implies warning, but class isn't explicit.

has_production_effect

c4 verified · fact Derate (output reduced or limited)

Limit percentage is variable; the 50 percent figure is only an example

c7 drafted · lead String configuration correction

When the measured input voltage is above the operating range maximum

review note: support check: partial - Check PV generator configuration when voltage is above range is stated, but 'string configuration correction' is a slightly stronger action.

c8 drafted · lead Contact manufacturer service

When the measured voltage is within range, which points to an internal malfunction
