AC Fan System LEDs
Each AC fan inverter has a red and green diagnostic LED. The diagnostic LEDs
can be used to determine whether the AC fan inverter board must be replaced.
These LEDs can only be viewed when the AC fan inverter board is removed from
the drive and energized with an external power supply and control circuitry.
DC Fan System LEDs
Each DC fan inverter has a red, yellow and green diagnostic LED. The diagnostic
LEDs can be used to determine whether the DC fan inverter board must be
replaced. These LEDs can only be viewed when the DC fan inverter board is
removed from the drive and energized with an external power supply and control
circuitry.
ATTENTION: The inverter LEDs are only operational when the drive is
energized, and only visible with the protective covers removed from the power
structure. Servicing energized equipment can be hazardous. Severe injury or
death can result from electrical shock, burn or unintended actuation of
controlled equipment. Follow Safety related practices of NFPA 70E, ELECTRICAL
SAFETY FOR EMPLOYEE WORKPLACES. DO NOT work alone on energized
equipment!
