5. Persediaan dan Pemasangan

Pemasangan yang betul adalah penting untuk prestasi dan keselamatan inverter.

1. Pemasangan: Choose a secure, dry, and well-ventilated location. Ensure sufficient clearance for airflow around the inverter, especially near the cooling fans.
2. Sambungan Input DC:
   • 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.
   • Pastikan semua sambungan adalah ketat dan selamat.
3. Pembumian: Connect the inverter chassis to a reliable earth ground using a suitable grounding wire.
4. Sambungan Output AC:
   • 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.
5. 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.
6. Kawalan Jauh (Pilihan): If using a remote control unit (e.g., CR-10), connect it to the designated RS-232 port.

Penting: Always ensure the inverter is OFF before making any connections.

6. Operasi

Follow these steps to operate your COTEK SD3500-112 GFCI inverter:

1. Hidupkan kuasa: Ensure all DC and AC connections are secure. Switch the inverter's main power switch to the "ON" position.
2. Petunjuk Status: 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.
3. Beban Menyambung: Plug your AC appliances into the GFCI outlets. Ensure the total wattagkuasa peralatan yang disambungkan tidak melebihi 3500W.
4. Ujian GFCI: Periodically press the "TEST" button on the GFCI outlets to ensure they are functioning correctly. Press "RESET" after testing.
5. Mod jimat tenaga: If configured, the inverter may enter a power-saving mode when no load or a very light load is detected, reducing quiescent current draw.
6. Automatic Transfer Switch (ATS): If an AC input source is connected, the inverter will automatically switch to that source when available, prioritizing it over battery power. When the AC input is lost, it will switch back to inverter (battery) power.
7. Matikan: Disconnect all AC loads, then switch the inverter's main power switch to the "OFF" position.

7. Penyelenggaraan

Penyelenggaraan berkala memastikan jangka hayat dan operasi inverter anda yang boleh dipercayai.

• Pembersihan: Pastikan inverter bersih dan bebas daripada habuk dan serpihan. Gunakan kain kering untuk mengelap bahagian luar. Jangan gunakan pembersih cecair.
• Pengudaraan: Ensure cooling vents are clear and unobstructed. Periodically check for dust buildup in the fan areas.
• Sambungan: Periodically check all DC and AC connections for tightness. Loose connections can cause overheating and poor performance.
• Kesihatan Bateri: Monitor the health of your battery bank. A weak battery can affect inverter performance.
• Ujian GFCI: Test the GFCI outlets monthly to ensure proper function.
