4. Setup and Installation
IMPORTANT: Installation must be carried out by a certified electrician in accordance with all applicable electrical standards and regulations.
- Pre-Installation Check: Verify that the meter's specifications (voltage, current) match the electrical supply and load requirements. Inspect the meter for any physical damage.
- Mounting: Securely mount the meter in a dry, protected location, ensuring adequate ventilation and accessibility for reading and maintenance.
- Wiring: Connect the incoming and outgoing electrical cables to the designated terminals as per the wiring diagram provided with the meter. Ensure all connections are tight and secure.
- Power On: Once wiring is complete and verified, restore power to the meter. The display should illuminate, indicating successful power-up.
- Initial Configuration (if applicable): Depending on the utility provider, initial configuration or pairing with a Customer Interface Unit (CIU) may be required. Refer to specific utility guidelines or the CIU manual for details.
5. Operating Instructions
5.1. Prepaid Mode Operation
In prepaid mode, the meter requires a valid STS (Standard Transfer Specification) token to supply electricity. Tokens are typically purchased from your utility provider.
- Entering a Token: Use the numeric keypad to enter the 20-digit STS token.
- Confirming Entry: After entering all digits, press the 'Enter' or 'Red' button (if available) to confirm.
- Token Validation: The meter will validate the token. A successful entry will add credit to your meter, and the supply will be restored (if disconnected). An invalid token will result in an error message on the display.
- Checking Credit: The display typically shows the remaining credit or units. Consult your utility provider's specific instructions for display navigation to view detailed credit information.
5.2. Post-Paid Mode Operation
In post-paid mode, the meter continuously measures electricity consumption. Billing is handled by your utility provider based on periodic readings.
- Reading Consumption: The display will show the current electricity consumption (e.g., in kWh).
- Display Navigation: Use the meter's buttons (if any, typically indicated by arrows or specific symbols) to cycle through various display parameters such as current consumption, voltage, current, and power factor.
5.3. Customer Interface Unit (CIU) Integration
The Mk32 meter can operate wirelessly with EDMI CIUs like the HD18 and HD21. This allows users to interact with the meter (e.g., enter tokens, check credit) from a convenient indoor location without direct access to the meter itself. Refer to the specific CIU manual for pairing and operational instructions.
6. Maintenance
The EDMI Mk32 meter is designed for minimal maintenance. However, periodic checks can help ensure its longevity and accurate operation.
- Cleaning: Gently wipe the meter's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture.
- Visual Inspection: Periodically inspect the meter for any signs of physical damage, loose connections, or tampering. Report any anomalies to your utility provider immediately.
- Environmental Conditions: Ensure the meter remains within its specified operating temperature and humidity ranges.
7. Troubleshooting
This section addresses common issues you might encounter with your EDMI Mk32 meter.
- No Power/Display Off:
- Check the main circuit breaker.
- Ensure there is sufficient credit (in prepaid mode).
- If the issue persists, contact your utility provider.
- Invalid Token Error:
- Double-check the token digits for accuracy.
- Ensure the token is valid for your specific meter.
