Applicable Industries

Product Series

Installation Requirements

1. Mount vertically on cabinet interior metal mounting plate with four rear M4 fixing screws
2. Maintain minimum 30 mm clearance left and right of enclosure to ensure cooling fan airflow circulation
3. AC input wiring must use 1.5 mm² cross-section copper wire with cabinet protective ground connection
4. Adjust front panel voltage trim potentiometer to calibrate DC output to standard 28 V DC before connecting load equipment
5. Wire ALARM dry contact terminals to upper cabinet PLC fault monitoring input channel for real-time power failure alert

Use & Maintenance Precautions

1. Strictly prohibit DC output load current exceeding rated 9 A continuous full-load capacity
2. Clean side panel fan dust filter screen every 3 months to prevent heat accumulation activating over-temperature protection shutdown
3. Confirm AC input voltage selector switch matches local grid voltage before power-on operation; mis-setting burns internal power components
4. Cut off AC input power supply before disassembling enclosure cover for internal inspection; internal circuits carry dangerous high AC voltage
5. Do not install the power supply unit adjacent to heat-generating equipment such as servo drives and contactors
6. Short-circuit test of DC output terminal blocks is prohibited; repeated short-circuit triggers permanent damage to secondary circuit chips
