Best Practice Methods
General Wiring
In addition to properly grounding the system and separating high and low voltage utilities
implement the following wiring methods during installation to ensure proper system performance.
• Communication wiring from MCC to SCC MUST BE CAT-5E stranded wire; otherwise, PLC
will not be able to communicate with VFD’s.
• All communication wiring must be isolated. Never run CAT-5E stranded communication wire
in the same conduit as 3-phase wiring or use extra CAT-5E stranded wire as a method of
wiring additional connections from MCC to SCC.
• Avoid parallel runs of 3 Phase and control wiring inside the MCC Enclosure.
• Do not use the MCC or SCC panel as junction boxes. Do not bring wires into these panels
unless they are to be terminated in that panel.
• Do not use SCC power or neutral wires as a method of powering items such as “Point of
Sales” or back-room outlets.
• Do not use solid core wire for terminations within MCC and SCC panels
• Make sure appropriate size shielded wire is used between SCC and the HMI (E-1063 Human
Machine Interface) and is properly grounded to shield only in SCC.
• Make sure Euro cable connections are correct and verify shield and ground are connected
to ground terminal.
• Never install conduit or cord grips in the top of an enclosure.
• Re-tighten all wire connections approximately one week after installation. This time frame
should have allowed the system to experience vibration from standard operation and some
change in temperature. Doing so will ensure all connections are good.
