General Wiring Guidelines:
- Connect the auxiliary power supply (AC/DC 85-265V) to the L and N terminals.
- For current measurement, connect the current transformers (CTs) to the Ia*, Ia, Ib*, Ib, Ic*, Ic terminals. Ensure correct polarity.
- For voltage measurement, connect the phase voltages (Ua, Ub, Uc) and neutral (Un) to the corresponding terminals.
- If using RS485 communication, connect the A and B lines to the RS485 terminals.
- Connect digital inputs (DI1-DI4) and digital outputs (DO1-DO4) as required for your application.
- Analog outputs (AO1-AO4) can be configured for 0/4-20mA or 0-5/10V transmission.

Troubleshooting
If you encounter issues with your TTAMG Digital Energy Meter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or power | No power supply; incorrect wiring; blown fuse (external) | Check power supply connections and voltage. Verify auxiliary power wiring. Check external fuses in the circuit. |
| Incorrect readings (Voltage/Current) | Incorrect wiring polarity for CTs/PTs; incorrect CT/PT ratio settings; loose connections | Verify all current and voltage wiring connections against the diagrams. Ensure CT/PT ratios are correctly configured in the meter's settings. Tighten all terminal screws. |
| RS485 communication failure | Incorrect wiring (A/B lines reversed); incorrect baud rate/protocol settings; bus termination issues | Check RS485 A and B line connections. Verify baud rate and communication protocol (MODBUS-RTU) settings match the master device. Ensure proper bus termination if multiple devices are on the network. |
| Display frozen or unresponsive | Temporary software glitch; power instability | Cycle power to the meter (turn off and on). If the problem persists, contact support. |
