Warnings and Cautions
Static Precautions EMC incorporates state-of-the-art technology in its designs, including
the use of LSI and VLSI components. These chips are very susceptible
to damage caused by static discharge and need to be handled
accordingly.

containing LSI and/or VLSI components, observe the following
precautions:

board.
• Unless specifically designed for non-disruptive replacement,
never plug or unplug printed-circuit boards with the power on.
Severe component damage may result.
