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.
