7. Maintenance and Disposal
Regular inspection of the PV system is an important safety precaution to ensure trouble-
free operation of the entire PV plant and the
DLX
inverter.
Danfoss
is committed to its policy of environmental responsibility, and therefore appeals to
end users who are disposing of inverters to follow local environmental legislation and to
seek safe and responsible means of disposal.
7.1. Regular System Inspection
The
DLX
inverters are designed and manufactured to operate trouble-free for many years.
Performing regularly maintenance will ensure high efficiency and a longer service life for
the inverters.
NOTICE
•
Prior to service and maintenance work the inverter should always be
disconnected on both the AC and the DC sides and discharged to avoid shock
hazards.
•
For service or maintenance the inverter must be de-energized for
1 hour
to
discharge the capacitor bank.
•
The inverter upper cover is to be opened only by
Danfoss
service persons or
service partners authorized by
Danfoss
due to danger of damage to internal
components and invalidated warranty.
