6. Installation and Maintenance Recommendations

Installation

• Electrical Connection: Please refer to Atlas Copco’s official wiring diagram (usually marked on the back of the driver) to ensure correct power supply phase sequence, phase and current wiring.
• Fixing Method: Usually fixed inside the tool body with screws or buckles. Be careful not to over-tighten to avoid casing deformation.

Maintenance

• Cleaning: Regularly remove dust and oil stains around the driver to prevent poor heat dissipation.
• Connection Inspection: Regularly check whether the input and output cables are loose or worn.
• Fault Detection: The driver is usually equipped with status indicators (such as running, fault, undervoltage). If an abnormality occurs, please first cut off the power supply, check the line or contact professional maintenance personnel.
