The wiring of main circuit and control circuit should be separated to prevent
erroneous actions.
;
Please use shield wire for the control wiring and not to expose the peeled-off net in
front of the terminal.
;
Please use the shield wire or tube for the power wiring and ground the two ends of
the shield wire or tube.
;
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-VJ 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.
