Distances
• Hardware and software maintenance on device entails opening the front cover.
Check that the correct installation safety distances are observed in order to allow
routine check and maintenance operations.
• Provide sufficient working space in front of the inverter that allows to open the front
covers and to make the internal connections.
• Install at a height which takes into consideration the weight of the appliance and in a
position which is suitable for servicing, unless suitable means are provided to carry
out the operation.
• If possible, install at eye-level so that the status LEDS (08) can be seen easily.

• Respect the minimum distances from objects around the inverter that could prevent
the inverter installation and restrict or block the air flow.
The minimum clearance distances depends from multiple factor:
Ventilation flow on the rear side of the inverter. Depending of the support where the
inverter is installed it changes the upper (A) required free space: if the inverter is in-
stalled on a support without any openings (e.g. a wall), the heat flow will be entirely
directed to the top of the inverter; for this reason the upper (A) minimum required
free space must be 50 cm.
Otherwise in case of the inverter is installed on a support with openings (e.g. frame
installation) the heat can freely flow on the rear side of the inverter; so the upper (A)
minimum required free space can be reduced to 15 cm.

• 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 recom-
mended 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 ra-
dius, 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 on the right side and 30cm on the left side.

In case of manual installation, using handles (04), consider a free side space to lift the inverter of 60 cm minimum.
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.
