6.  Maintenance
Repeat test of the trigger circuit by the system operator
The system operator must ensure that the equipment required for parallel 
operation with the low-voltage network is always in proper technical condi-
tion. To this end, it is required to have an electrically skilled person check the 
protective devices for proper functioning at regular intervals. This require-
ment is deemed to be satisfied for normal and environmental conditions if the 
test intervals mentioned in BGV A3 are adhered to. The repeat test shall in-
clude at least the following:
 
Check of the environmental conditions (pollution, mechanical or isola-
tion damage).
 
A tripping control of the coupling switch.
 
Press the "TEST" button to trigger the coupling switch. 
 
Tripping must be visualised by the coupling switch.
The trigger circuit NS protection/coupling switch, in the wiring diagram of this 
operating manual consisting of K1/K2 and coupling switch 1/coupling switch 
2, separates the power generation system from the public low-voltage grid. 
By checking the trigger circuit regularly, sticking of the contactors can be 
detected at an early stage.
