- Equipped with overcurrent, overvoltage, and phase-loss protection, the SHR5E safeguards motors from damage. Its built-in bypass contactor and thermal management extend component life, while the 1-year warranty and reliable construction ensure peace of mind for long-term industrial applications.
Product installation and instructions
- Preparation and Mounting: Begin by ensuring the power supply is disconnected. Securely mount the SHR5E soft starter on a stable surface using appropriate screws. Ensure the enclosure is flame-retardant and positioned away from heat sources for optimal safety and performance.
- Wiring Configuration: Connect the input power supply to terminals L1, L2, and L3. Link the motor wires to T1, T2, and T3, ensuring tight connections. Utilize the built-in bypass contactor terminals if required, and verify all wiring aligns with the system’s electrical standards.
- Parameter Setup: Access the concentrated knob-type adjustment panel. Configure start/stop times, initial voltage, and current limits based on load requirements. The intuitive interface simplifies setting multi-mode regulations, such as soft start or stepless speed control.
- Cooling and Ventilation Check: Confirm the built-in cooling fan operates smoothly before energizing the system. Ensure vents remain unobstructed to maintain stable operating temperatures, enhancing the device’s lifespan and preventing overheating during prolonged use.
- Testing and Commissioning: After installation, power on the system and monitor the display for normal operation indicators. Test multiple start modes under load conditions to validate performance stability. Regularly inspect connections and housing integrity to ensure long-term reliability.
Note： When using the SHR5E series soft starter, ensure proper installation in a well-ventilated, dry environment. Avoid damp or high-temperature areas. Follow electrical connection guidelines strictly. Adjust parameters per load requirements and avoid unauthorized modifications. Regularly inspect and clean the device, avoiding corrosive cleaners. Only qualified personnel should perform maintenance to ensure safety and compliance.
