DIN-Rail Mounting 
The aluminum DIN-Rail attachment plate should already be fixed to the back 
panel of IE-SW-PL18M when you take it out of the box. If you need to 
reattach the DIN-Rail attachment plate to IE-SW-PL18M, make sure the stiff 
metal spring is situated towards the top, as shown by the following figures. 
STEP 1—Insert the top of the 
DIN-Rail into the slot just below the 
stiff metal spring. 
STEP 2—The DIN-Rail attachment 
unit will snap into place as shown in 
the following illustration. 
To remove the IE-SW-PL18M from the DIN-Rail, simply reverse Steps 1 and 
2 above.
