The Ankerui APSM manual explains installation, wiring, operation, and troubleshooting of the DC power monitoring system.
This manual introduces the APSM DC power monitoring system, covering its purpose, applicable battery ranges (20 Ah‑100 Ah), and overall architecture. It details the integrated monitoring module, inspection and insulation units, and the touch‑screen display.
The document provides technical parameters, wiring diagrams, configuration steps, and operational guidance such as real‑time fault monitoring, charge‑discharge curves, and system settings, along with appendices for the battery inspection and insulation detection units. This manual is written in Chinese.
