CAUTION
If you have any questions about the
grounding your equipment and/or
the electrical box, contact a qualified
electrician.
To minimize electrical
noise and eliminate ground
currents, ground the chassis
as shown. Use a STAR
configuration (illustrated
below). Do not DAISy
CHAIN the grounds.

Earth Ground
Power Grounding
For safety, the MPC-E chassis must be properly grounded. This system
ground connection must be attached to an earth ground potential at the
electrical box that supplies power to the enclosure or cabinet in which the
MPC-E system is installed.
The ground connection should comply with all requirements specified by
the National Electrical code and any other local codes or ordinances that
are applicable.
Chassis Grounding Stud (PE)
Proper grounding for the MPC-E chassis is essential for the effective
suppression of electrical noise or RFI (Radio Frequency Interference). The
power line ground is mandatory and must be connected from the grounding
PE stud to the nearest grounded metal pipe or equivalent earth ground.
This will improve the chassis ground connection and may be needed in noisy
industrial environments.
NOTE
The chassis grounding stud is used
to attach a protective earth ground
to the MPC-E module. This helps
suppress electrical interference or
radio frequency interference (RFI)
that is common in an industrial
environment.
