MOD CHOKE T

What does FF89 mean?

An overtemperature condition has been detected in the choke of a liquid-cooled R8i inverter module. This indicates that the choke's temperature has surpassed its safe operating threshold.

• Over-temperature condition detected on a choke or filtering component.
• Excessive current flowing through the choke.
• Choke saturation or damage.
• Poor ventilation around the choke.

1. 1

   Inspect the inverter cooling fan for proper operation, obstructions, or unusual noises.

2. 2

   Measure the ambient temperature around the inverter module and verify it is within the specified operating range.

3. 3

   Check the liquid cooling system for adequate flow, pressure, and coolant level to ensure effective heat removal.
