From 2000 m to 4000 m (6.600 ft to 13.200 ft) above sea level - reduction of maximum voltage (600 V for
500...600 V models and 690 V for 500...690 V models) of 1.1 % for each 100 m (330 ft) above 2000 m
(6.600 ft).

Humidity: from 5 % to 95 % non-condensing.
Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution. Condensation
shall not originate conduction through the accumulated residues.

3.1.2 Mounting Considerations

Consult the inverter weight at the
and Table 8.4 on page
3
Mount the inverter in the upright position on a flat and vertical surface.
External dimensions and fixing holes position according to the
3-4 and Figure 3.2 on page
details.
First mark the mounting points and drill the mouting holes. Then, position the inverter and firmly tighten the
screws in all four corners to secure the inverter.
Minimum mounting clearances requirements for proper cooling air circulation are specified in
3-5, Figure 3.5 on page 3-9
Inverters of frame sizes B and C can be arranged side-by-side with no clearance required between them. In this
case, the top cover must be removed as shown in
Do not install heat sensitive components right above the inverter.
ATTENTION!
When arranging two or more inverters vertically, respect the minimum clearance A + B

plate so that the heat rising up from the bottom inverter does not affect the top inverter.
ATTENTION!
Provide conduit for physical separation of the signal, control, and power conductors (refer to
