6.3 Repair
>
Before carrying out repair work, temporarily decommis-
sion the entire photovoltaic installation (
¬
page 3 ).
>
Replace any defective components.
>
Do not carry out any repairs in the connection box.
>
Start up the photovoltaic installation again (
¬
page 5 ).
7 Inspection and maintenance
>
Follow the inspection and maintenance plan in the
appendix.
>
Temporarily decommission the photovoltaic installation
>
(
¬
page 3 ).
7.1 Checking the insulation and stability of the
cabling
>
Check the cabling, insulation and plug connections for
cleanliness, integrity and stability.
>
Document and eliminate all faults.
7.2 Checking the end and middle clamps
>
Check all of the end and middle clamps on the photovol-
taic modules to ensure that they are correctly connected
to the mounting frame and the PV module frame.
7.3 Checking the protective earthing
>
Check the cabling of the protective earthing for cleanli-
ness, integrity and stability.
7.4 Completing inspection and maintenance
work
>
Document the inspection work that was carried out in an
inspection report.
>
Point out to the end user that they must always keep the
inspection report safe.
>
Start up the photovoltaic installation again (
¬
page 5 ).
8 Decommissioning
8.1 Permanently decommissioning the
photovoltaic installation
>
Observe the instructions for the inverter.
>
Cover the photovoltaic modules with an opaque plastic
film or a fleece in order to minimise the generation of
direct current.
8.2 Removing the photovoltaic module
>
Decommission the photovoltaic installation.
>
Remove the photovoltaic modules and observe the infor-
mation on the electrical installation and set-up.
