5. セットアップとインストール

5.1 取り付け

図5.1: 製品寸法

This diagram provides the physical dimensions of the VFD inverter. The overall length is 147mm (5.79in). The front panel dimensions are 60mm (2.36in) wide and 102mm (4.02in) high, with a mounting hole spacing of 52mm (2.05in) horizontally and 90mm (3.54in) vertically. The depth of the unit is 80mm (3.15in). Mounting holes have a diameter of 4mm (0.16in). Ensure adequate ventilation space around the unit.

Mount the VFD in a well-ventilated area, away from direct heat sources, moisture, and vibrations. Use the provided mounting holes to secure the unit. Ensure sufficient clearance for air circulation, especially around the cooling fan.

5.2配線

Refer to Figure 4.2 for terminal locations. Follow these steps for wiring:

1. 電源入力: Connect the single-phase AC power supply (176-264V) to the "AC" input terminals. Ensure correct polarity if specified, though for AC, it's typically not critical.
2. モーター出力： Connect the three-phase motor's U, V, W terminals to the VFD's "U", "V", "W" output terminals respectively.
3. 接地: Connect the "FG" terminal to a reliable earth ground. This is crucial for safety and to prevent electromagnetic interference.
4. 制御配線（オプション）: If using external control (e.g., potentiometer, external switches, PLC), connect them to the appropriate "X" terminals, "GND", "V+", or "COM" as per your application requirements and the VFD's programming parameters.

重要： Double-check all wiring connections before applying power to prevent damage to the VFD or connected equipment.
