## **Assembling and Installation Method** 

## Installation method 

- ¡ About DIN-Rail Attachment available with DIN EN60715 TH 35 (35×7.5mm or 35×15mm) (Top hat shaped DIN rail) 

- ¡ Below shows mounting orientation. 

If install other then standard mounting orientation (A), please fix 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 direction 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.

## **Assembling and Installation Method** 

- ¡ Shown below the notes about installation clearance of a unit. 

- 1 Installation clearance at above and below the unit. 

- Please have clearance of at least 25mm above and below the unit to avoid heat accumulation. 

- 2 Installation clearance at the side of the unit. 

- Please have clearance of at least 5mm side the unit to insulating the internal components. However, refer to right figure, if adjacent device of the unit (including power supply) is a heat source.
