Issue:
When replacing and ATV58 by an ATV61, what is the LO (output contactor)?

Product Line:
ATV61/71

Environment:
All range, All serial number

Cause:
None.

Resolution:
The LO is assigned to OCC. It is Output Contactor Command. The ATV61 does not have LO. The R1 and R2 relays on ATV61 are already being used in the circuit. Need to use any available contact off of the Run Command Relay and wire 24V through it to pull in the Drive Isolation contactor.
