6. Installation and Maintenance

Installation Points

• Environmental Requirements: Should be installed in a dry and well-ventilated environment to avoid dust and corrosive gas erosion. It has certain requirements on temperature and humidity (such as operating in -30°C – +55°C environment).
• Power Supply Requirements: Ensure that the power supply voltage is consistent with the rated voltage of the equipment, and that it is equipped with grounding protection.

Maintenance

• Daily Maintenance: Keep the equipment clean, regularly check the oil level and oil quality of hydraulic oil (if applicable); check the connection status of sensors and electrical lines.
• Calibration: Perform regular calibration to ensure the accuracy of measurement data such as force value and displacement. Professional calibration is recommended every six months to one year.
• Lubrication: For mechanical transmission parts (such as lead screws), regularly add lubricating oil to prevent wear.
