the Turbocor application organization.
6.13 Equipment Panel
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:
l
All metal parts should be properly connected to ensure an electrical connection. Connect panel doors
with braided cable.
l
Keep power cables and interface cables separate. Use metal cable glands for shielded cables.
l
The wire-loom going to the panel door should be shielded using a metal-braided hose that is
connected to ground at both ends.
l
Electrical panel must have a dedicated ground conductor in accordance with relevant electrical safety
regulations.
l
Verify that the panel ground conductor is sized in accordance with relevant electrical safety
regulations.
NOTE
l
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.
l
Special filtering and measuring may be required in installations such as hospitals that are prone to being influenced by other
electronic equipment.
