The minimum clearance distances depends from multiple factor:
•
Ventilation flow on the top side of
the inverter.
The upper
(A)
minimum
required free space must be
25 cm
.
•
Possible flooding or damage during
grass cutting.
It changes the bottom
(B)
required free space: If the inverter
is installed in a place where there are
risks of flooding or there is need to
cut the grass growing underneath
the unit, the bottom
(B)
minimum
recommended free space is 50 cm;
otherwise in case the inverter is
installed in a place where there’s no
risks of flooding or grass cutting
evenience, the bottom
(B)
minimum
required free space can be reduced
to 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. In any case minimum 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
.
ATTENTION – A
In case of manual installation (using handles (04)) consider a free side space to lift
the inverter of 60 cm minimum.
ATTENTION – A
In case of installation with lifting equipments (eyebolts and ropes) the side distances
(C) could be reduced at the minimum required but a subsequent manual lifting it will no longer be
possible: in this case the lifting equipments must remain available on the field for any subsequent
operation.
Installation of multiple units
• When installing multiple 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 specified in the
following graph.
• The 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 deflector is 30cm.
