Wire the Safe Torque-off Circuit

This section provides guidelines for wiring safe torque-off connections to your
Kinetix 5700 drive.
IMPORTANT When replacing 2198-xxxx-ERS3 (series A) single-axis and dual-axis
inverters with 2198-xxxx-ERSx (series B) inverters, you must use the
series B (safety) connector plugs that are included with your series B
inverter.
Install 2198-xxxx-ERS3 (series A) Safety (STO) Connector Plugs
The right side of the safety connector plug requires an off-center push when
inserting it into the STO connector. This applies to 2198-xxxx-ERS3 (series A)
single-axis and dual-axis inverters.
IMPORTANT An off-center push is required to engage the locking features on the
bottom of the safety connector plugs and seat properly with the drive
STO connector. Failure to do this can result in the connector plug pulling
out of the drive connector during normal operation.
