4.1 Wiring Diagrams
Proper wiring is crucial for accurate measurement and safe operation. Refer to the diagrams below for different phase configurations. Always ensure power is disconnected before performing any wiring.
For non-visual users, the image displays three wiring diagrams:
- Single phase two wires: Shows connections for L (Live) and N (Neutral) to the voltage input terminals, and current transformer (CT) connections to the current input terminals.
- Three phase three wires: Illustrates connections for L1, L2, L3 to the voltage input terminals, and CT connections for each phase to the current input terminals.
- Three phase four wires: Details connections for L1, L2, L3, and N to the voltage input terminals, and CT connections for each phase to the current input terminals.
Always consult the product label on the rear of the device for specific terminal markings and voltage/current ratings before making connections.
5. Operating Instructions
The Smart X96-5E features a backlit LCD display and several buttons for navigation and configuration.
5.1 Front Panel Overview
The display typically shows L1, L2, L3 voltage readings and accumulated kWh. Other parameters like current, power factor, and frequency can be accessed using the navigation buttons.
5.2 Button Functions
- Ph S / ESC: Likely used to cycle through phase displays (L1, L2, L3) or to exit a menu/setting.
- V/A: Used to display Voltage and Current parameters.
- MD PF Hz: Used to display Maximum Demand, Power Factor, and Frequency.
- P: Likely used to display Power (kW, kVar, kVA).
- E: Used to display Energy (kWh, kVarh). This button may also be used to enter configuration mode or confirm selections.
5.3 Configuration Software
The meter supports free configuration software for advanced settings and selectable measurement modes. This software allows you to configure the meter for specific kWh display types, including Total kWh (Import + Export), Import kWh, and Net kWh (Export - Import). Refer to the software's documentation for detailed instructions on its use.
5.4 RS485 Modbus RTU Communication
The meter is equipped with RS485 Modbus RTU for remote data acquisition. For detailed information on the Modbus protocol and register map, please refer to the official Eastron website or contact customer support.
6. Maintenance
The Smart X96-5E energy meter is designed for reliable operation with minimal maintenance. Keep the display and casing clean using a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure proper ventilation around the unit to prevent overheating. Regular checks of wiring connections for tightness and integrity are recommended.
7. Troubleshooting
If you encounter issues with your Smart X96-5E meter, consider the following common troubleshooting steps:
- No Display: Check power supply connections and ensure the rated voltage is applied. Verify the panel cut-out dimensions and mounting are secure.
- Incorrect Readings: Double-check all wiring connections against the appropriate wiring diagram (Single phase two wires, Three phase three wires, or Three phase four wires). Ensure current transformers (CTs) are correctly installed and oriented. Verify the CT ratio settings in the configuration software.
- Communication Issues (RS485): Check RS485 wiring for correct polarity (A/B). Verify baud rate and address settings in both the meter and your communication system. Ensure termination resistors are correctly applied if necessary.
- Buttons Unresponsive: Ensure the meter is not in a locked mode. If the issue persists, a power cycle (disconnect and reconnect power) may resolve it.
For persistent issues or complex problems, please contact Eastron customer support.
