How to use

Mount the power supply on a suitable DIN rail inside the control cabinet and secure according to installation instructions and local electrical regulations. Connect the AC input supply to the designated input terminals and verify correct grounding. Wire the 24 V DC output to the load terminals, observing polarity and ensuring the combined load does not exceed the rated 10 A. After wiring, apply mains power and confirm output voltage and load operation using appropriate measuring equipment. Follow standard lockout/tagout procedures while installing or servicing the unit.

Usage recommendations

Install the unit in a well-ventilated cabinet location, avoid excessive ambient temperatures and allow clearance for heat dissipation. Use appropriately rated wiring and overcurrent protection on the input and output circuits. Perform periodic inspections of connections and verify that cumulative load remains within the rated current to ensure long-term reliable operation.
