5. Тохиргоо ба суурилуулалт
Proper installation is crucial for the inverter's performance and safety.
- Суурилуулалт: Choose a secure, dry, and well-ventilated location. Ensure sufficient clearance for airflow around the inverter, especially near the cooling fans.
- DC оролтын холболт:
- Connect the positive (+) terminal of the 12V battery bank to the positive (+) DC input terminal on the inverter.
- Connect the negative (-) terminal of the 12V battery bank to the negative (-) DC input terminal on the inverter.
- Use appropriately sized cables to minimize voltage drop and ensure safe operation. Refer to electrical guidelines for cable sizing based on current and distance.
- Бүх холболтууд нягт, найдвартай байгаа эсэхийг шалгаарай.
- Газардуулга: Connect the inverter chassis to a reliable earth ground using a suitable grounding wire.
- AC гаралтын холболт:
- Plug your AC appliances directly into the GFCI outlets on the inverter.
- For hardwired applications, consult a qualified electrician to connect to the AC output terminals.
- AC Input Connection (for ATS function): If using the automatic transfer switch, connect a reliable AC power source (e.g., shore power, generator) to the AC input terminals.
- Алсын удирдлага (заавал биш): If using a remote control unit (e.g., CR-10), connect it to the designated RS-232 port.
Чухал: Always ensure the inverter is OFF before making any connections.
6. Үйл ажиллагаа
Follow these steps to operate your COTEK SD3500-112 GFCI inverter:
- Асаах: Ensure all DC and AC connections are secure. Switch the inverter's main power switch to the "ON" position.
- Статусын үзүүлэлтүүд: Observe the LED indicators on the inverter (if present) for status such as power, fault, or overload. Refer to the full manual for detailed indicator meanings.
- Холболтын ачаалал: Plug your AC appliances into the GFCI outlets. Ensure the total wattagхолбогдсон цахилгаан хэрэгслийн e нь 3500Вт-аас хэтрэхгүй.
- GFCI тест: Periodically press the "TEST" button on the GFCI outlets to ensure they are functioning correctly. Press "RESET" after testing.
- Цэнэг хадгалах горим: If configured, the inverter may enter a power-saving mode when no load or a very light load is detected, reducing quiescent current draw.
