Fig.3-7 Installation of controller (CR751)
Fixing installation section sure for prevention from the fall, when using the controller
placing vertically. The reference figure of the metal plate for fixing is shown in Fig. 3-8.
You should install the metal plate for fixation to the controller with M4 x 8 or the shorter
screw. The screw projection length inside the controller (side board thickness is 1.2mm)
surely makes 6.8mm or less.
When storing the controller in a cabinet, etc., take special care to the heat radiating
properties and ventilation properties so that the ambient temperature remains within the
specification values. And, don't install the controller in the position where direct rays or
the heat of lighting hits. The skin temperature of the controller may rise, and the error
may occur.
