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 pages 11-13 and HW01 pages 14-16.

HW00 (Standard – Modbus RTU / BACnet MS/TP – Modbus TCP / BACnet IP)

Note:

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

24 VAC/VDC operating only with safety isolating transformer according EN 61558-2-6.
