The ODES GRUS-11Z Voltage Switch Service Manual provides technical specifications, wiring diagrams, installation, debugging, and maintenance instructions…
The GRUS-11Z is a voltage switching relay designed for power system protection interfaces, offering selectable input voltages of 110 V DC or 220 V DC, a rated current range of 0.25 A‑4 A, and built‑in monitoring functions for breaker position and control circuit status. Its compact, snap‑fit design allows panel‑mount installation without screws, and it meets strict insulation and dielectric strength requirements.
The manual details the device’s technical parameters, panel description, functional principles, and step‑by‑step debugging and maintenance procedures. It includes wiring diagrams, terminal definitions, test voltage requirements, and inspection steps for both closing/opening circuits and anti‑jump protection, enabling technicians to verify correct operation and perform adjustments safely. This manual is written in Chinese.
