Furuno DRS2D/DRS4D/DRS4A/DRS6A/DRS12A/DRS25A Radar Sensor Installation Guide

About this manual

The manual provides safety instructions for installing Furuno radar sensors, including the requirement to wear a safety belt and hard hat and to ground the equipment to prevent electrical shock. It details system configuration, power supply options (100/110/220/230 VAC, 12‑24 VDC) and NMEA 2000 connectivity, as well as the equipment lists for each sensor model.

Mounting procedures describe platform construction, bolt torque (19.6‑24.5 N·m), and safe distances to magnetic compasses and RF radiation zones. Wiring sections cover cable routing for the sensor, power supply units (PSU‑012, PSU‑013) and optional accessories. The document ends with packing lists, outline drawings, interconnection diagrams and warranty terms.
