Connections
Normally, the line reactor, EMI/EMC filter(s), and the harmonic filter will be installed in a
panel. This could be the same panel where the controls are located. When designing a panel,
attention should be given to the following recommendations:
• All metal parts should be properly connected to ensure an electrical connection.
Connect panel doors with braided cable.
• Separate panel into sections for power and interface/control functions (all
electrical components and practices should follow all applicable local codes and
standards).
• Keep power cables and interface cables separate. Use metal cable glands for
shielded cables.
• The wire-loom going to the panel door should be shielded using a metal-braided
hose that is connected to ground at both ends.
• Electrical panel must have a dedicated ground conductor in accordance with
relevant electrical codes.
• Verify that the panel ground conductor is sized in accordance with relevant
electrical codes.
6.11 Equipment Panel
NOTE
The installing electrical contractor is responsible for connecting the panel ground to the facility ground in accordance with
relevant electrical codes and standards, such as NEC Section 250 in the U.S. or its equivalent for other countries.
Special filtering and measuring may be required in installations such as hospitals that are prone to being influenced by other
electronic equipment.
