The inverter contains dangerous high‑voltage parts and must not be opened under any circumstances; attempting to do so can cause electric shock or injury.
Transport the unit by holding the radiation fin (heat sink) rather than the front cover, use the eye‑bolts for lifting, and avoid pulling on cables.
Connect the ground terminals to a resistance of 100 Ω or less for 200‑V AC models, or 10 Ω or less for 400‑V AC models.
