¡Below shows mounting orientation.
 Ifinstallotherthenstandardmountingorientation(A),pleasex
the power supply for withstand the impact and vibration.
¡When you mount a power supply on a DIN rail, have the area
marked A catch one side of the rail and push the unit to the direc-
tion of B. To remove the power supply from the rail, either push
down the area marked C or insert a tool such as driver to the area
marked D and pull the unit apart from the rail.
When you couldn’t remove the unit easily, push down the area
marked C while lightly pushing the unit to the direction of E.
