Rectifier Troubleshooting
Symptom
Possible Cause(s)
Suggested Action(s)
Power Indicator
(Green) Off
No input voltage.
Make sure there is input voltage.
Internal input fuse open.
Replace the rectifier.
Protection Indicator
(Yellow) On
AC input under/over voltage.
Correct the AC input voltage to within the acceptable range.
PFC under/over voltage.
Replace the rectifier.
Moderate load sharing imbalance.
Check if the rectifier is properly seated in the module mounting
assembly. If this does not correct the fault, replace the rectifier.
Rectifier not inserted into the slot completely. Remove and properly insert the rectifier.
Rectifier over-temperature protection.
Fan rotor blocked: remove any object that may be blocking the fan.
Ventilation blocked (inlet or outlet): remove any object that may be
blocking the inlet or outlet.
Ambient temperature too high or rectifier inlet too close to a heat
source: lower the ambient temperature or relocate the heat source.
Rectifier in ECO Standby Mode when ECO
Mode is active in controller.
--
Protection Indicator
(Yellow)
Flashing
Loss of communication with controller (the
rectifier can provide power).
Check the communication cables.
Remove and properly insert the rectifier and controller.
Alarm
Indicator
(Red) On
Severe load sharing imbalance.
Rectifier output disabled for any reason,
including overvoltage shutdown and internal
output fuse open.
Rectifier addresses contradictory.
Turn AC power to the rectifier off or remove the rectifier, wait 30
seconds or more (until the LEDs on the rectifier extinguish), then turn
the AC power to the rectifier on or re-insert the rectifier. If rectifier
fails to start, shuts down again, or load sharing imbalance persists;
replace the rectifier.
Alarm Indicator
(Red) Flashing
Fan not operating (rectifier shuts down).
Replace the fan.

Replacement Procedures
3.2.1
Rectifier Replacement
DANGER!
Take care when removing a rectifier that was in operation, as rectifier surfaces could be very hot.
WARNING!
To prevent damage to the latching mechanism, ensure the handle is in the open position when installing or
removing a rectifier Module. NEVER hold the handle in the closed position when installing a rectifier into a shelf.
The rectifier is hot swappable. It can be removed and installed with the system operating.
Procedure
1.
Performing this procedure may activate external alarms. Do one of the following. If possible, disable these alarms. If these
alarms cannot be easily disabled, notify the appropriate personnel to disregard any alarms associated with this system while
this procedure is performed.
2.
On the rectifier to be removed, loosen the captive fastener securing the top of the latch mechanism to the front of the
rectifier. Pull the top of the latch mechanism away from the rectifier (this will retract the latch mechanism located on the
underside of the rectifier). This unlocks the rectifier from the shelf. Refer to
for latch mechanism illustration.
3.
Slide the rectifier out by pulling forwards.
4.
Place the replacement rectifier into the mounting position without sliding it in completely.
