Provides instructions for the safe operation of Hitachi inverters.
This manual covers essential safety precautions for the J300 series inverter, including high‑voltage warnings, grounding requirements, and personal protective equipment. It stresses that only qualified personnel should install, adjust, and service the equipment.
The document details installation, wiring, and operation procedures, describing input voltage ranges, enclosure size recommendations, protection functions, and troubleshooting steps. Standard specifications such as enclosure type, input power, frequency range, and control settings are listed in the specifications section.
| Enclosure type | Semienclosed (IP20) |
|---|---|
| Rated AC input voltage | 200‑220 V or 380‑415 V, 50/60 Hz |
| Output frequency range | 0.1 Hz to 400 Hz |
| Frequency accuracy (digital command) | ±0.01 % |
| Acceleration/Deceleration time | 0.01 s to 3000 s (adjustable) |
Power must be disconnected, the unit should be grounded, safety glasses worn, and work performed on an insulating pad with only one hand on live parts.
It accepts three‑phase 200‑220 V (or 200‑230 V) and 380‑415 V (or 400‑460 V) at 50 or 60 Hz.
A separate motor thermal switch or overload device must be installed, as the inverter does not include built‑in overload protection.
