NI recommends that you replace the RM-16061 within the ETX-1630x when the switch count on any one of the contactors reaches 1 million cycles.

Prior to replacing the RM-16061, place a sturdy table adjacent to the human-machine interface side of the rack to minimize vertical movement of the RM-16061.
Note Lifting the RM-16061 requires two people. Ensure there is enough space near the crate to place the new RM-16061 after lifting it out of the crate.

  8. Install a new RM-16061 into the rack.
Validate the RM-16061 before connecting to the adapter. NI recommends using the FDT-16050 and the ETX Inverter Production Test System Maintenance Software to validate the RM-16061 replacement.
