Figure 16-4: Removal of filter
“ACBOX Area”
NOTICE
NOTE
: Before replacing the filter, make sure
that it is perfectly dry and turn the knob of
the power switch to 0.
If no further checks are necessary, replace
the panel.
16.1.2
Visual and screw inspections
To check that screws are tight, the inverter must be opened. This implies the absolute necessity of
disconnecting the whole system: on both the DC and the AC sides.
DANGER
If it is necessary to operate on exposed parts (not protected by
panels), it is not sufficient to turn the grid switches (AC) and field
switches (DC) to 0 (OFF), because the input cables are always
under voltage!
Turn off and disconnect the inverter.
