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.

• Do not install any object (e.g. AC or DC cables) that could be damaged by
overheating from outgoing hot air flow from top and side fan sections (ΔT= +15 °C
compared to ambient temperature). In case of this kind of installation needs, please
evaluate the installation of a proper air deflector. Always respect the minimum
distances required.
• 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 top side of the inverter. The upper (A) minimum required
free space must be 25 cm / 10".

• 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 50cm / 20"; 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 / 6".
• Cables bending radius. Sides (C) minimum required free
space may depends from cable type (cable dimension, bend-
ing radius, etc..): this evaluation must be done by the installer
during the plant design phase (refer to “Cable routing” chap-
ter for more information). In any case minimum required free
space for proper ventilation of the unit (near side fans) cannot
be under 15 cm / 6" on the right side and 30cm /12" on the left
side.

In case of manual installation, using handles (04), consider a free side space to lift the inverter of 60 cm / 24" 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.
