Symptom Likely Causes Action
“Range RECTIFIER” alarm for the
rectifier is activated.
Corrupted data found on the
EEPROM inside the rectifier that is
inside the allowable data range but
programmed.
Try adjusting the RECTIFIER
parameters to se if the EEPROM
cells can be updated. If not, replace
the faulty rectifier.
6.1 TO REMOVE A RECTIFIER MODULE OR A CONTROLLER
Lift the securing latch in the centre divider adjacent to the module and pull the module out of the Power shelf.
When removing modules, especially if the ambient temperature is high and the unit has been operating at maximum
load, avoid skin contact with the metal casing as it may be too hot to touch. Pull the unit halfway out of the
magazine and let cool for 2-3 minutes before handling.
6.2 TO INSERT A RECTIFIER MODULE OR A CONTROLLER
Insert the module into the slot and ensure alignment with the fold-out rails in the magazine. Push the module all the
way in so the rear connector fully mates and the securing latch spring clicks back down into place.
