# Terminal Connections in MacSet LX1

## External Power Supply
MacSet also supports direct external power input (12–24 V DC):
- Ensure wiring is done as per MacSet and the sensor manufacturer’s power and polarity specifications.
- This is ideal for installations where continuous power is available and high-frequency data logging is required.

### Connecting External Sensors

- **Check Sensor Specifications**  
  Ensure compatibility with MacSet's input requirements.

- **Power Off the device**  
  Turn off MacSet before making any connections.

- **Attach Sensor Cables**  
  Connect cables to the appropriate inputs on MacSet, following the sensor manufacturer’s pin 
configuration and power on device.

- **Configure via Maya App**  
  Power on MacSet and configure it using the Maya app to adjust settings as per your needs.

### Connecting External Power Supply

- **Verify Power Supply**  
  Confirm the power supply matches MacSet's 12-24 V requirement. Turn off both MacSet and the 
power source before connecting.

- **Connect Power Cable , Insure safety**  
  Turn off MacSet before making any connections.
