 Installation Instructions

Complete all installation work under power-off condition, and confirm no residual voltage in the circuit before wiring. This PV load break switch supports multiple installation methods, suitable for cabinet fixing and standard DIN rail mounting. Arrange internal wiring reasonably, connect positive and negative cables in standard rules, and fasten terminals properly to prevent overheating caused by loose connection. After installation, check the overall structure to ensure flexible switching movement, complete protective parts and safe working performance.

 Operation Guidelines

Before closing the switch, inspect circuit and load conditions to eliminate hidden risks, then push the handle steadily to the closed position for normal operation. For equipment maintenance and system shutdown, switch the handle to the fully open position, and confirm circuit disconnection through visible break design. Use lockable device if needed to prevent unauthorized misoperation. Do not operate the switch with excessive force in daily use. Keep the device clean and dry through regular inspection and maintenance, so as to ensure long-term stable and safe operation of photovoltaic DC power system.
