5. Орнотуу жана орнотуу

Туура орнотуу инвертордун иштеши жана коопсуздугу үчүн абдан маанилүү.

  1. Монтаждоо: Choose a secure, dry, and well-ventilated location. Ensure sufficient clearance for airflow around the inverter, especially near the cooling fans.
  2. DC киргизүү туташуу:
    • 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.
    • Көлөмдү азайтуу үчүн тиешелүү өлчөмдөгү кабелдерди колдонуңузtage drop and ensure safe operation. Refer to electrical guidelines for cable sizing based on current and distance.
    • Бардык байланыштар бекем жана коопсуз экендигин текшериңиз.
  3. Негиздөө: Connect the inverter chassis to a reliable earth ground using a suitable grounding wire.
  4. AC чыгаруу туташуусу:
    • 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. Алыстан башкаруу (кошумча): If using a remote control unit (e.g., CR-10), connect it to the designated RS-232 port.
