Technical Data; Inspection And Maintenance Work - Overview - Vaillant VPV P Series Operating, Installation And Maintenance Instructions

6.3 Repair
> Before carrying out repair work, temporarily decommis-
sion the entire photovoltaic installation.
> Replace any defective components.
> Do not carry out any repairs in the connection box.
> Start up the photovoltaic installation again.
7 Inspection and maintenance
> Follow the inspection and maintenance plan in the
appendix.
> Temporarily decommission the photovoltaic installation.
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.
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.
