Grounding the MC-7400
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
grounding screw (M6) to the grounding surface prior to connecting the
power as shown in the illustrations below:
NOTE
A 4 mm2conductor must be used when the connection to the
external grounding screw is utilized. The heat sink is grounded to
the chassis by an internal screw.
