Troubleshooting

The following is a list of the most common situations where the equipment does not perform as intended, the most likely cause, and a possible corrective action.

If the suggested corrective action does not return the equipment to normal operation, contact Schneider Electric for assistance.

Situation	Possible cause	Corrective action
The RPP has no input power.	No input source available.	Restore input source. Check the wiring continuity between the RPP input and the input source.
Specific output circuit(s) have no power.	Associated branch circuit breaker(s) is OFF.	Turn the branch circuit breaker(s) ON.
	The wiring between the branch circuit breaker(s) and the equipment is incorrect.	Check for wiring continuity and correct phase sequence between the branch circuit breaker(s) and the equipment.
	The equipment associated with the branch circuit breaker is operating above the rated load.	Schedule a load check of the equipment with Schneider Electric; adjust for load balance if possible.
	The branch circuit breaker is inoperable.	Replace the inoperable branch circuit breaker.
No output from the RPP, but the display is active.	The main input circuit breaker is tripped.	Record which alarm indications are active. Reset alarm(s) and clear external signal. Check the alarm history in the display for reasons why the main input circuit breaker tripped. Below is a list of possible causes: Output overload. Schedule a load check of the RPP with Schneider Electric. Inoperable main input circuit breaker. Replace the main input circuit breaker. Short circuit internal to the RPP. Troubleshoot the RPP or contact Schneider Electric.
Output from the RPP is on, but the display is not active.	Control power fuse(s) blown.	Replace fuse(s).
Overvoltage/undervoltage.	Upstream UPS or power conditioner is inoperable.	Correct problem at the input source.
Overvoltage/undervoltage.	Voltage drop due to distance or excessive load on output.	Reduce the distance or reduce the load.
