5. Installation & Maintenance
Installation Guidelines
- Location Selection: Should be installed in a dry, well-ventilated location away from direct strong light to ensure display effect.
- Power Connection: Ensure the use of a stable DC power supply (usually 24VDC) and check the polarity.
- Grounding: Due to the metal housing, proper grounding is recommended to prevent electromagnetic interference.
Maintenance Points
- Environment Inspection: Regularly check the operating environment temperature and humidity to ensure they are within the rated range (0℃-50℃, humidity 10%-90%).
- Cleaning & Maintenance: Wipe the screen gently with a soft, dry cloth. Avoid using corrosive cleaners to prevent damage to the capacitive touch layer.
- Software & Hardware Inspection: Regularly check if the interface connections are firm, and confirm that the main control board and display are properly connected to avoid display abnormalities caused by looseness.
