- Possible flooding or grass cutting evenience. It changes the bottom
(B) or the rear (D - only in case of horizontal installation) required free
space: If the inverter is installed in a place where there are concrete
risk of flooding or grass cutting evenience, the bottom (B) or the rear
(D - only in case of horizontal installation) minimum recommended free
space is 50 cm; otherwise in case of the inverter is installed in a place
where there aren't risk of flooding or grass cutting evenience, the bottom
(B) and rear (D - only for horizontal installation) minimum required free
space must be 15 cm.
- Cables bending radius. Sides (C) minimum required free space may
depends from cable type (cable dimension, bending radius, etc..): this
evaluation must be done by the installer during the plant design phase
(refer to "Cable routing" chapter for more information). In any case mini-
C
mum required free space for proper ventilation of the unit (near side
fans) cannot be under 15 cm on the right side and 30cm on the left side.
In case of manual installation (using handles) consider a free
side space to lift the inverter of 60 cm minimum.
In case of installation with lifting equipments (eyebolts and ro-
pes) the side distances (C) could be reduced at the minimum
required but a subsequent manual lifting it will no longer be pos-
sible: in this case the lifting equipments must remain available
on the field for any subsequent operation.
Installation of multiple units
OK
• When installing multiple units position the inverters side by side paying
PVS-120
attention to keep the minimum clearance distances (measured from the
NO
outer edge of the inverter) for each inverter specified in the side graphs.
OK
• The vertical installation of two inverters positioned back to back is also
permitted on a structure which must be composed of a 2 or 3 frame
supports (refer to "Mounting with a support bracket" paragraph). In this
case the minimum recommended distance between the units in order
to avoid the use of an air deflector is 30cm.
