5 - Installation
- Possible ooding 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 ooding 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 ooding or grass cutting evenience, the bottom
(B) and rear (D - only for horizontal installation) minimum required free
space must be 15 cm.
- Cables curvature radius. Sides (C) minimum required free space
may depends from cable type (cable dimension, curvature 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 minimum required free space for proper ventilation of the unit
(near side fans) cannot be under 15 cm.
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 of 15 cm but a subsequent manual lifting it will no lon-
ger be possible: in this case the lifting equipments must remain
available on the eld for any subsequent operation.
Multiple units installation
• In case of multiple installation of units, position the inverters side by side
paying attention to keep the minimum clearance distances (measured
from the outer edge of the inverter) for each inverter.
• 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” chapter). In this
case the minimum recommended distance between the units in order
to avoid the use of an air deector is 30cm.
