4.2 Wiring Connection
Image 4.2: Connection Guideline for the amiciSmart Intelligent 3 Phase to 1 Phase Selector Switch.
- Input Connections: Connect the main Neutral (N) wire and the three Phase (L1, L2, L3) input wires from your three-phase supply to the corresponding 'IN' terminals located at the top of the device.
- Output Connections: Connect the Neutral (N) wire and the single Phase (L) output wire to your load (e.g., home electrical system) to the 'OUT' terminals located at the bottom of the device.
- Verify: Double-check all connections for tightness and correct polarity. Ensure no bare wires are exposed.
5. Operating Instructions
Once installed and wired correctly, restore power to the device. The device will power on and begin operation.
5.1 Initial Power-Up and Display
Image 5.1: Real Time Voltage Display and Protection Indicators.
- Upon power-up, the device will perform a self-check.
- The LED displays will show real-time voltage readings for each phase (L1, L2, L3) and the current ampere draw of the active phase.
- The L1, L2, or L3 indicator will light up to show which phase is currently supplying power.
5.2 Parameter Adjustment
To customize settings such as voltage protection thresholds, overcurrent limits, and phase priority:
- Press the 'SET' button to enter the parameter adjustment menu.
- Use the Up and Down arrow keys to navigate through the different parameters (e.g., Over Voltage, Under Voltage, Over Current, Power On Delay, Phase Priority).
- When the desired parameter is displayed, press 'SET' again to select it for adjustment.
- Use the Up and Down arrow keys to change the value of the parameter.
- Press 'SET' to confirm the new value and move to the next parameter or exit the menu.
