5. Installation & Operation Guide

1. Snap the DIN rail power supply firmly onto standard 35mm DIN rail inside a ventilated electrical cabinet, lock the bottom buckle to prevent sliding.
2. Connect AC mains live (L), neutral (N) and ground (FG) wires to the upper input terminal block according to marking labels.
3. Wire DC load positive (+V) and negative (-V) cables to the lower DC output terminals, strictly match load rated 24V voltage.
4. Switch on AC input power, the power supply outputs stable 24V DC to drive PLC, sensors or PV monitoring modules.
5. When overload, overvoltage or short-circuit fault triggers protection, the unit will lock DC output; cut off AC input power to troubleshoot before restarting.
6. Reserve small ventilation gaps between multiple rail power supplies to avoid heat accumulation during long-term full-load operation.
