WARNING!
1. Short-circuiting [B2] or [-] to [+2/B1] can damage the AC motor drive.

Grounding terminals (

Make sure that the leads are connected correctly and the AC drive is properly grounded.
(Ground resistance should not exceed 0.1 Ω .)
Use ground leads that comply with local regulations and keep them as short as possible.
Multiple VFD-B units can be installed in one location. All the units should be grounded
directly to a common ground terminal, as shown in the figure below. Ensure there are no
ground loops.
