HW00 / HW01
- To prevent any possible damage to the product caused by incorrect cabling or wiring, we have introduced a version of the TA-Smart PCBA (HW01) with improved electrical wiring.
- Both PCBA versions are fully functional, but have slightly different wiring configurations.
- Ensure to choose the correct technical documentation based on the PCBA’s HW version.
- The PCBA version (HW00 or HW01) can be found on the sticker in the SmartBox and the wiring instruction for each hardware version. HW00 and HW01.

Note:
- A, B and M terminals are NOT isolated from all other terminals.
- GND (M – 0V) is common to power supply, analog signals and RS 485.
- In case of AC power supply, L24 and M should be connected to the same phase for each TA-Smart.
- GND (0V) of analog input/output should be connected to 0 VAC/VDC on the controller side.
