Installation Orientation
Install the Inverter vertically so as not to reduce the cooling effect. When installing the Inverter,
always provide the following installation space to allow normal heat dissipation.

Horizontal Space
1. The same space is required horizontally and vertically for IP00, IP20 and NEMA 1 Inverters.
2. Always remove the top protection cover after installing an Inverter with an output of 18.5 kW or less in a
panel.
Always provide enough space for suspension eye bolts and the main circuit lines when installing an
IMPORTANT
Inverter with an output of 22 kW or more in a panel.
IMPORTANT
Installation of Inverters and EMC filters
For an EMC rules compliant installation
consider the following points:
•
Use a line filter.
•
Use shielded motor cables.
•
Mount the inverter and filter on a
grounded cunductive plate.
•
Remove any paint or dirt before mount-
ing the parts in order to reach the low-
est possible grounding impedance.
