„ 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. A B Air 50mm min. 30mm min. 30mm min. 120mm min. Air Horizontal Space Vertical Space Fig 2 Installation 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 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: PE L1 L2 L3 Ground Bonds Remove any paint! • Use a line filter. • Use shielded motor cables. • Mount the inverter and filter on a grounded cunductive plate. PE • Remove any paint or dirt before mount- ing the parts in order to reach the low- est possible grounding impedance. Inverter GND L1 L2 L3 GND U V W Cable Lenght as short as possible Grounded Metal Plate Screened Motor cable Ground Bonds Remove any paint!
