Control Connections - Nidec Commander C200 Guide

Electrochemical corrosion of grounding terminals
Ensure that grounding terminals are protected against corrosion i.e. as could be caused
by condensation.
WARNING
The drive must be connected to the system ground of the AC supply. The ground wiring must
conform to local regulations and codes of practice.
The ground loop impedance must conform to the requirements of local safety regulations.
The drive must be grounded by a connection capable of carrying the prospective fault
current until the protective device (fuse, etc.) disconnects the AC supply.
The ground connections must be inspected and tested at appropriate intervals.

Control connections

The control terminals are configured by default for the arrangement shown below:

** Commander C300 uses 'Safe Torque Off' so terminal 11 is unassigned on the Commander C300. When using a
Commander C300 refer to the 'Safe Torque Off' wiring instructions above.
After completing step 6 re-fit the terminal cover (refer to step 5).
