INSTALLATION & STARTUP

Chapter 5 Electrical

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, 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.
