Preparations 
 
(1)  Insert the tool into the two tool insertion holes (one on the top 
and one on the bottom) and release the hooks.   
(2)  Insert the tool in the gap between the front panel and rear case, 
and pull out the front panel slightly. Grip the front panel and pull 
out fully. Be sure not to impose excessive force on the panel.   
(3)  When inserting the E5CSV, check to make sure that the sealing 
rubber is in place and push the E5CSV toward the rear case until 
it snaps into position. While pushing the E5CSV into place, push 
down on the hooks on the top and bottom surfaces of the rear 
case so that the hooks are securely locked in place. Make sure 
that electronic components do not come into contact with the 
case. 
* Do not remove the terminal block. Doing so will result in 
malfunction or failure.
