8.9 Procedure for dismantling the equipment
WARNING –
B
The dismantling operations must be carried out with the equipment disconnected from any voltage sources. Refer
to
“Inverter total de-energization and safe access”
paragraph on this manual to know all the necessary step to safely operate
on the inverter.
ATTENTION –
A
Never open the power module
(01)
or wiring box
(02)
in the case of rain, snow or a level of humidity >95%. Always
carefully seal all unused openings.
Even though the device is equipped with an anti-condensation valve, air with extremely high levels of humidity can lead to the creation of
condensation inside the inverter.
As the inverter is almost completely insulated from the outside, condensation can also form after maintenance interventions in certain
weather conditions.
ATTENTION –
A
During dismantling always protect the inverter parts that are installed and exposed to the weather elements!
ATTENTION –
