This document is the instruction manual for the L300P Series inverter, describing the features and characteristics of the inverter.
This manual covers safety messages, definitions and symbols, and general precautions required for installing, wiring, and maintaining the Hitachi L300P series inverter. It emphasizes high‑voltage hazards, proper grounding, and the need for qualified personnel during installation and service.
Detailed sections describe mounting cautions, wiring specifications, power‑up test procedures, and troubleshooting tips. The document also includes an index of warnings, technical terms, and reference tables for torque, thermal protection, and wiring gauges.
| Input voltage (L model) | Three‑phase 200 to 240 V 50/60 Hz |
|---|---|
| Input voltage (H model) | Three‑phase 380 to 480 V 50/60 Hz |
| Maximum motor ground resistance | < 0.19 Ω |
You should wait at least five (5) minutes after turning off the input power supply before performing maintenance or an inspection.
Use short‑time‑invariant and pulse‑current‑sensitive ground fault interrupter breakers with a higher trigger current.
The L300P accepts three‑phase 200‑240 V 50/60 Hz (L models) or three‑phase 380‑480 V 50/60 Hz (H models).
Confirm that incoming power for the alarm connection is completely disconnected before removing the front cover.
