Note
This guide only applies to EG4xxx meters. Legacy EG30xx and eGauge2 meters do not support the Sensor Hub or the EV1000.
Example Wiring Diagram
Example Configuration
Notes:
- All hardware must be installed in a suitably rated enclosure. eGauge Systems offers several powered enclosure kits which are suitable for this purpose. Most kits feature DIN rails (for mounting the eGauge meter and EV1000s securely) along with a powered receptacle and optional stepdown transformer (which can be used to power the 5Vdc supply for the sensor hubs and/or other supporting hardware).
- Sensor Hubs must be powered. Up to 2 hubs can be powered directly from the eGauge via the USB ports on the meter. For installations where more hubs are required or the USB ports are in use (e.g., for Modbus RTU communication) the hubs can be powered directly from a generic 5Vdc power supply.
- The eGauge must have a separate power source in this configuration. This can either be an AC power supply connected to the L1 and N terminals providing 120Vac - 277Vac or a DC power supply connected to the Ldc terminal providing 12-60Vdc. Note that correct polarity is required when using a DC power supply.
