Replacement & Compatibility FAQ
Q: Can the FR-PU02ER replace the FR-PU02?
A: Yes, in most cases. The FR-PU02ER is an enhanced version of the FR-PU02 with improved display. Connector and protocol are compatible with the same inverter series.
Q: Is the FR-PU02ER compatible with FR-A700 series inverters?
A: Not directly. The FR-A700 series uses a different PU port connector. An adapter may be available — contact us to confirm.
Q: Can I use the FR-PU02ER to copy parameters between two inverters?
A: Yes. The parameter copy function allows you to read parameters from one inverter and write them to another of the same model series.
Q: What is the difference between FR-PU02ER and FR-PU04?
A: The FR-PU04 offers an improved LCD display and additional monitoring functions. Both are compatible with FR-A500/F500 series inverters. The FR-PU04 is the recommended upgrade if the FR-PU02ER is unavailable.
Q: Do you supply genuine Mitsubishi Electric parts?
A: Yes. Konmask.com supplies genuine OEM Mitsubishi Electric components. We do not sell counterfeit or unauthorized copies.
