Horizontal placement
Use the rubber foot (4 positions) at the bottom of the controller as it is, or put the
spacer, and leave the space between the installation side and the controller
installation side more than 7mm when you fix the controller with the installation
screw.In the other case, the air intake hole at the bottom of the controller is
occupied, and temperature rises in the board, and causes the trouble.

Note1)

The space required for cooling is 100 mm minimum. Reserve approximately 500 mm of space
behind the unit as the maintenance work area.
