4.1.2 Commissioning steps for the dual-VFD air compressor 

It is recommended to use touch screen special for INVT air compressor to display and commission. 

Note: 

 

If you use a controller from another manufacturer, contact INVT technical support. 

 

All the parameters displayed in the interfaces are subject to actual displayed content. 

The commissioning steps are as follows: 

1. Perform wiring according to Figure 4-1 and ensure that the VFD for air compressor and the housing 

of the air compressor are grounded properly. 

2. After power up, the following interface is displayed.
