Describes the installation method, usage precautions, and main technical indicators of dry capacitors
The document describes the proper installation environment for the capacitor, including dry, well‑ventilated locations and required clearances. It also details terminal wiring, transport precautions and re‑energising procedures.
Technical data such as rated voltage, capacity, tolerance, loss angle, withstand voltage, insulation resistance, operating temperature, humidity, altitude limits and self‑discharge characteristics are listed, together with required safety protections and applicable standards. This manual is written in Chinese.
