4. インストール
インバーターを安全かつ効率的に動作させるには、適切な設置が不可欠です。以下の手順を慎重に実行してください。
4.1 インバータの取り付け
- 直射日光、熱源、湿気を避け、乾燥した風通しの良い場所を選んでください。
- インバーターは不燃性の表面に設置してください。
- Ensure there is at least 6 inches (15 cm) of clear space around all sides of the inverter for proper airflow.
- Use appropriate fasteners to secure the inverter firmly to the mounting surface.
4.2 DC入力接続
警告： Ensure the battery bank is disconnected or isolated before making any connections. Use appropriately sized cables and fuses/breakers.
- Connect the positive (+) DC cable (typically red) from your 48VDC battery bank to the red positive (+) terminal on the inverter's rear panel.
- Connect the negative (-) DC cable (typically black) from your 48VDC battery bank to the black negative (-) terminal on the inverter's rear panel.
- Ensure all DC connections are tight and secure to prevent loose connections and arcing.
- Install an external DC fuse or circuit breaker between the battery bank and the inverter's positive terminal, as close to the battery as possible. Consult the specifications for appropriate fuse sizing.
4.3 AC出力接続
The SP-4000-148 uses a hardwire AC output connection.
- Ensure the inverter is OFF and all DC power is disconnected.
- Connect your AC load wiring to the designated AC output terminal block on the front panel.
- Follow all local electrical codes for AC wiring.
- Ensure all AC connections are secure.
4.4 接地
The inverter chassis must be properly grounded.
- Connect a ground wire from the chassis ground terminal on the inverter's rear panel to a reliable earth ground point.
- Ensure the ground connection is secure and meets all local electrical codes.
4.5 リモートコントロール接続（オプション）
If using an optional remote control, connect it to the green terminal block on the front panel according to the remote control's instructions.
5. 操作
Once the inverter is properly installed and all connections are secure, you can begin operation.
5.1 電源のオン/オフ
- Ensure all DC and AC connections are correct and secure.
- If an external DC breaker is installed, ensure it is closed (ON).
- Flip the main power switch on the inverter's front panel to the 'ON' position.
- The LED indicators will illuminate, and the cooling fan may briefly activate.
- To power off, flip the main power switch to the 'OFF' position.
5.2つのLEDステータスインジケータ
The inverter features 3-color LED indicators to display its operational status:
- 緑色のLED： 通常の動作を示します。
- 黄色のLED： Indicates a warning or abnormal condition (e.g., low battery, minor overload). Refer to troubleshooting.
- 赤色LED： Indicates a fault or critical error (e.g., severe overload, over-temperature, short circuit). The inverter will typically shut down. Refer to troubleshooting.
5.3 DIPスイッチの設定
The DIP switches on the front panel allow configuration of output frequency and voltage. Refer to the detailed specifications or the label on the inverter for specific switch positions for desired settings.
- 出力周波数: Select between 50 Hz or 60 Hz.
