2. ข้อมูลด้านความปลอดภัย

• อันตรายจากไฟฟ้า: Installation and servicing must be performed by qualified personnel only. Ensure power is disconnected before installation or maintenance.
• เล่มที่tagอี ช่วง: ห้ามใช้เกินปริมาตรการทำงานที่กำหนดไว้tagมีช่วงแรงดันไฟฟ้าตั้งแต่ AC90-250V.
• หม้อแปลงกระแส: ตรวจสอบให้แน่ใจว่า CT clamp is correctly installed around the live wire as per the wiring diagram. Incorrect installation may lead to inaccurate readings or damage.
• สิ่งแวดล้อม: Do not expose the device to extreme temperatures, humidity, or corrosive environments beyond the specified operating conditions (-20-55℃, ≤90% non-condensing humidity).
• ถอดชิ้นส่วน: Do not attempt to disassemble or modify the device. This will void the warranty and may pose a safety risk.

5. คู่มือการติดตั้ง

Follow these steps for proper installation. Ensure all power is disconnected before proceeding.

1. การติดตั้ง: Install the Smart Energy Monitor onto a standard 35MM DIN rail within your electrical panel.
2. การเดินสายไฟหลัก: Connect the Live (L) and Neutral (N) wires from your circuit breaker to the corresponding 'L' and 'N' input terminals on the monitor.
3. Connecting the CT Clamp: Pass the live wire of the circuit you wish to monitor through the opening of the CT clamp. Connect the CT clamp's wires to the 'CT' input terminals on the monitor. Ensure the polarity is correct: connect the black wire of the CT to the '-' terminal and the white wire to the '+' terminal.
4. Connecting Load (Optional): If using the 10A dry output to control a load, connect the load's control wires to the output terminals.
5. เปิดเครื่อง: เมื่อเชื่อมต่อทั้งหมดอย่างปลอดภัยและได้รับการตรวจสอบแล้ว ให้จ่ายไฟให้กับวงจรอีกครั้ง
