Tighten the screws within the range of specified torque.
If the screws are 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.
 Shut off the external power supply (all phases) used in the system before mounting or removing
the module.
Failure to do so may result in damage to the product.
 Do not directly touch any conductive parts and electronic components of the module.
Doing so can cause malfunction or failure of the module.
