- 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.
- Remote Control (Opsional): 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:
- Daya Hurung: Ensure all DC and AC connections are secure. Switch the inverter's main power switch to the "ON" position.
- Indikator 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.
- Nyambungkeun beban: Plug your AC appliances into the GFCI outlets. Ensure the total wattage of connected appliances does not exceed 3500W.
- Uji GFCI: Periodically press the "TEST" button on the GFCI outlets to ensure they are functioning correctly. Press "RESET" after testing.
- Modeu Hemat Daya: If configured, the inverter may enter a power-saving mode when no load or a very light load is detected, reducing quiescent current draw.
- 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.
- Pareum listrik: Disconnect all AC loads, then switch the inverter's main power switch to the "OFF" position.
