Wiring
1. The ATS is equipped with screw-type terminals, each with a width of 7.4 mm, suitable for copper wires with a cross-sectional area of 1 to 16 mm². 2. When wiring, strip the wire to a length of 12 to 13 mm; it is recomm ended to use a duckbill-shaped terminal for secure connection. 3. Tighten the screws with a recommended torque of 2.5 Nm to ensure proper tightening without damaging the terminals.

Important Notes
· The input power supply must be connected in the correct phase sequence. · Avoid using single-pole breakers for neutral/live control lines. · Switch neutral and live lines simultaneously to prevent malfunctions. · Prefer automatic mode for reliability; excessive manual use can cause contact wear. · Switch to manual mode only after power disconnection for maintenance. · Keep in automatic position normally; return to it after manual use. · For dual-power ATS, minimize switching and allow at least 1 minute between tests. · Only qualified personnel should operate the ATS while powered.
Working Conditions
· Altitude: Up to 2000 meters · Operating Temperature Range: -5°C to +40°C (24-hour average must not exceed +35°C) · Storage Temperature Range: -25°C to +55°C (transient peaks up to +70°C) · Operating Humidity: Up to 50% at +40°C; up to 90% at -5°C (condensation prevention required) · Contamination Level: Level 3 · Protection Rating: IP30 · Overvoltage Category: Category III (main circuit), Category II (control/auxil iary circuits) · Mounting Orientation: The ATS can be installed vertically or horizontally in cabinets. For specific installation requirements, please get in touch with us.
Cautions
· Professional Installation: Only qualified professionals should install and commission the Automatic Transfer Switch (ATS). · Installation Environment: Install the ATS on a clean, dry surface with adequate airflow. · Electrical Connections: Ensure all connections are secure to prevent overheating and fire hazards. · Avoid Neutral-Ground Bonding: Do not connect the neutral line to the grounding system, as this can create hazards. · Follow Local Regulations: Ensure compliance with applicable local electrical codes for safety and reliability.
Adhering to these guidelines ensures the safe operation of the ATS.
Maintenance
· Professional Inspection: Engage qualified personnel to regularly inspect the ATS, verifying proper operation. · Routine Cleaning: Periodically remove dust and debris to ensure optimal performance. · Electrical Contact Check: Inspect electrical contacts for wear or damage and tighten any loose connections to maintain reliable operation. · Humidity Control: Maintain a dry environment to prevent moisture-related malfunctions. · Insulation Testing: Routinely test insulation resistance to verify adherence to safety standards. · Proper Storage: Store the ATS in a protected environment, shielded from dust, humidity, and physical harm when not in use.
Adhering to these refined maintenance procedures ensures the safe and effective functionality of ATS.
