Frequently Asked Questions

Q: What inverter models is the CT75A-16T communication terminal compatible with?

A: The CT75A-16T RS-485 wiring terminal is designed for inverters and VFDs that use the RS-485 (485) communication protocol and a compatible CT75A-16T plug interface. We recommend verifying your inverter's communication port specification and terminal block model number against your device's manual before ordering to ensure a proper fit.

Q: Is this terminal block safe to install myself?

A: This is a non-electrified (passive) terminal component, meaning it does not carry a live charge on its own. However, always ensure the inverter system is fully powered down and isolated before making any wiring connections. If you are not experienced with electrical systems, consult a qualified electrician or technician.

Q: What cable gauge is compatible with the CT75A-16T terminal?

A: The CT75A-16T is designed for standard RS-485 twisted-pair communication cables commonly used in industrial environments. Refer to your inverter's documentation for the recommended cable specifications (typically 22–24 AWG shielded twisted pair for RS-485 runs).

Q: Where is this product made?

A: This product is made in Mainland China.
