c1 drafted · lead KACO blueplanet 87.0-165 TL3 Operating Manual EN 2020-10 (Siemens-hosted copy)

reports

c2 drafted · lead Low insulation resistance

Fault is located near the centre of the PV string; symmetrical fault resistances are also detected.

review note: support check: partial - Insulation error near the string centre and symmetrical fault resistances are stated, but low insulation resistance is only implied.

indicates

c3 drafted · lead Loss of electrical insulation

affects

c4 drafted · lead PV array

has_event_class

c5 drafted · lead Fault (device stops or needs intervention)

The fault must be rectified for safe operation.

review note: support check: partial - The passage says the faults must be rectified for safe operation, but doesn't explicitly class it as a fault.
