Installation Guide
1Prerequisites
Before installing, confirm the following are available:
2Physical Mounting
- The SM5000 enclosure has a DIN rail mount integrated into the rear panel.
- Snap the unit onto the DIN rail by hooking the top of the mount over the rail and pressing the bottom until it clicks.
- Verify the unit is secure and does not rock on the rail.
- Ensure adequate clearance above and below for cable routing.
3Ethernet and Power Connection
- Insert a standard RJ45 patch cable into the Ethernet port on the SM5000.
- Connect the other end to a PoE-capable switch port or PoE injector.
- The SM5000 has no power switch - it powers on as soon as the PoE connection is established.
- The LCD will display the boot sequence below, then transition to the device name and IP address within a few seconds.
① Boot
② Waiting for IP (DHCP only)
③ Normal operation
With static IP configured (factory default), state ② is skipped - the device applies the static IP directly and transitions immediately to ③. The 'Connecting... / Waiting for IP' state is only shown when DHCP is enabled.
4Sensor Connection
The SM5000 has three RJ12 sensor ports. Sensor Front and Sensor Rear use Ports 1 and 2, which share the same RS485 bus - the physical port each sensor is plugged into is therefore interchangeable. What determines which sensor is treated as Front and which as Rear is the Modbus address configured on the sensor itself (address 1 = Front, address 2 = Rear). Port 3 is dedicated to the calibration sensor and connects to a separate RS485 bus.
| Port 1 or 2 (indicative) | Modbus ID 1 - Sensor Front |
| Port 1 or 2 (indicative) | Modbus ID 2 - Sensor Rear |
| Port 3 | Modbus ID 3 - Calibration sensor only |
| Pin 1 | 24V DC (sensor power) |
| Pin 2 | B - RS485− |
| Pin 3 | A - RS485+ |
| Pin 4 | GND |
| Pin 5 | Reserved |
| Pin 6 | Reserved |
5First Boot Commissioning Checklist

| 4 | Verify MQTT broker IP and topic hierarchy | §2.4 |
| 5 | Change the web interface password | §5.3 |
| 6 | Confirm sensor readings are non-zero | §2.2.2 |
| 7 | Confirm MQTT shows Connected in System Status | §2.2.1 |
