F1300:
Slot C incompatible
accessory
Error during accessory firmware update.
Old inverter firmware version.
F1301:
Slot C Initialization Error
It was not possible to initialize a resource required for
the accessory to work.
- Resource already in use by another accessory.
In the case of communication network accessories,
only one accessory of each type of network can be
connected to the inverter at a time.
F1303:
Slot C accessory
connection
Loss of communication with the accessory.
- Above-supported electromagnetic noise.
- Vibration above supported limits causing connector
problems.
- Corrupted accessory firmware.
