5. Setup (Installation)

The Zerodis 3-Phase Digital LCD Voltmeter is designed for easy installation on a standard DIN rail. Follow these steps carefully:

1. Power Disconnection: Before beginning any installation, ensure that the main power supply to the circuit is completely disconnected and locked out to prevent accidental re-energization.
2. Mounting: Securely attach the voltmeter onto a standard 35mm DIN rail in your electrical panel. Ensure it clicks firmly into place.
3. Wiring: Connect the three-phase voltage lines (L1, L2, L3) and the neutral line (N) to the corresponding terminals on the voltmeter. Refer to the wiring diagram below for correct terminal assignments. Ensure all connections are tight and secure to prevent loose contacts and potential hazards.
4. Verification: Double-check all wiring connections against the diagram before restoring power.

This diagram provides a clear guide for wiring the Zerodis 3-Phase Digital LCD Voltmeter. It shows the connection points for the neutral (N) and three live phases (L1, L2, L3) to the voltmeter's terminals, ensuring safe and correct installation. The diagram labels input terminals V1~, V2~, V3~ and corresponding output terminals.

6. Operating Instructions

Once the voltmeter is correctly installed and power is restored to the circuit, the device will automatically begin monitoring and displaying voltage values.

1. Power On: After successful installation and power restoration, the voltmeter's LCD display will illuminate.
2. Voltage Display: The device will automatically show the real-time AC voltage values for each of the three phases (V1, V2, V3) on its digital screen. The readings are instantaneous and continuously updated.
3. Voltage Range: The voltmeter is designed to operate and accurately measure voltages within the range of 60V to 450V AC.
4. Switch Output: The integrated switch output converts the measured voltage signals into a digital format, which can be utilized for external control systems or data logging, depending on your specific application requirements. Refer to your system's documentation for integrating this digital output.

No complex configuration or button presses are typically required for basic voltage monitoring. The device is designed for straightforward, continuous operation.
