3.1 Handling Precautions
(1) Since the module case is made of resin, do not drop it or subject it to strong

ranges.
If the screw is too loose, it may cause the module to fallout, short circuits, or
malfunction.
If the screws are tightened too much, it may cause damage to the screw
and/or the module, resulting in fallout, short circuits or malfunction.
