Installation Points

1. Location Selection: Maintain good ventilation, avoid direct sunlight and high-temperature environments, and prevent the intrusion of dust and corrosive gases.
2. Fixation: Use DIN-rail or base bolt fixation to ensure the unit is level and minimize vibration transmission.
3. Wiring: Strictly follow the wiring diagram for wiring of power supply, output, control, and communication terminals, and use cables that meet the rated current requirements.
4. Grounding: Both the main unit and the control unit must be reliably grounded to prevent electromagnetic interference and safety accidents.
5. Heat Dissipation: Check the gap between the radiator and the unit to ensure the fan or water-cooling system operates normally.
