Distances
• Hardware and software maintenance on device entails removing 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 ap-
pliance 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 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 sup-
port 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.
C
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.
