5. Setup and Installation

5.1. Pre-installation Checklist

• Ensure the main power supply is OFF before starting installation.
• Verify that the device specifications match your electrical system requirements.
• Have appropriate tools (screwdriver, wire strippers, multimeter) ready.
• Confirm you have a standard 35mm DIN rail for mounting.

5.2. Mounting

1. Locate a suitable position on your electrical panel's 35mm DIN rail.
2. Align the device with the DIN rail and press firmly until it clicks into place.
3. Ensure the device is securely fastened and does not wobble.

5.3. Wiring Connections

Refer to Figure 3.1 for terminal locations. All wiring must be done with the main power supply disconnected.

1. Input Connections (IN):
   • Connect the incoming Neutral (N) wire from your power source to the 'N' terminal on the top (IN) side of the device.
   • Connect the incoming Live (L) wire from your power source to the 'L' terminal on the top (IN) side of the device.
2. Output Connections (OUT):
   • Connect the outgoing Neutral (N) wire to your load to the 'N' terminal on the bottom (OUT) side of the device.
   • Connect the outgoing Live (L) wire to your load to the 'L' terminal on the bottom (OUT) side of the device.
3. Ensure all wire connections are tight and secure to prevent loose contacts and overheating.

Note: The device is designed for single-phase AC 220V systems. Do not connect to three-phase systems or voltages outside the specified operating range.

6. Operating Instructions

6.1. Powering On and Display

1. After successful wiring, turn on the main power supply.
2. The device's digital display will illuminate, showing real-time voltage (V), current (A), and accumulated KWH.
3. The power button (usually a circle with a vertical line) can be used to manually turn the output ON/OFF.

6.2. Setting Protection Parameters

The device allows you to set thresholds for overvoltage, undervoltage, and overcurrent protection. Use the 'SET', 'Up' (▲), and 'Down' (▼) buttons.

1. Enter Setting Mode: Press and hold the 'SET' button for approximately 3-5 seconds until a parameter starts flashing on the display.
2. Navigate Parameters: Briefly press the 'SET' button to cycle through the different adjustable parameters (e.g., Overvoltage, Undervoltage, Overcurrent).
3. Adjust Value: When the desired parameter is flashing, use the 'Up' (▲) and 'Down' (▼) buttons to increase or decrease its value.
4. Confirm and Exit: After setting all desired parameters, press and hold the 'SET' button again for 3-5 seconds to save the settings and exit the setting mode. If no button is pressed for a certain period, the device may automatically exit setting mode, saving the last adjusted value.

Refer to Figure 4.1 for default/recommended setting ranges.

6.3. KWH Measurement

The device continuously measures and accumulates energy consumption in Kilowatt-hours (KWH). This value is displayed on the screen.

• The KWH reading provides an indication of total energy consumed through the device.
• Consult the device's specific interface for options to reset the KWH counter, if available. This is typically done by holding a specific button combination in setting mode.

7. Maintenance

• Cleaning: Periodically clean the device's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Inspection: Annually inspect wiring connections for tightness and signs of corrosion or damage.
• Ventilation: Ensure adequate ventilation around the device to prevent overheating.
• Firmware: This device typically does not require user-updatable firmware.

Always disconnect power before performing any maintenance.
