5.2.3 Distances
• Maintenance operations entails removing the front cover. Always
observe the required installation safety distances in order to allow
routine check and maintenance operations.
• Provide a sufficient working space in front of the inverter that
allows to open the front covers
(07)(54)
and to allows wiring
connections on the wiring box.
• Install at a height which takes into consideration the weight of
the unit and in a position which is suitable for servicing, unless
suitable means will be provided to carry out these mentioned
operations.
• If possible, install at eye-level so to allow to easily check the
status LEDs
(08)
.
• Respect the minimum distances from surrounding objects that
could prevent the inverter installation and restrict or block the air
flow.

ATTENTION –
A
Do not install any object (e.g. AC or DC
cables) that could be damaged by overheating from outgoing
hot air flow coming from 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.

The minimum clearance distances depends from multiple factor:
1. 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 installed 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.

or the rear (

- 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.
