Maintenance And Disposal; Regular System Inspection - Danfoss DLX 2.0 Installation Manual

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.
Refer to User Guide for more detailed information about the discharge procedure
of the capacitor bank and about regularly maintenance of the inverter.
