Installation
Wire Sizing
It is very important, with respect to safety and machine performance, that you use the proper
wire gauge for the installation. The table below identifies the amperage requirements for the
FX drives. Use this table as a guideline to determine the appropriate wire sizes to use for
proper installation.
.
Failure to follow safe installation guidelines can cause death or serious injury. AC power
lines that are longer than 50 feet may require a larger gauge than the values above. Follow
local electrical codes.
Wiring Techniques
If you are not sure of your grounding or signal wiring techniques, you should refer to the
recommended practices according to the IEEE Ground Book, ANSI Standard C1141 and the
National Electric Code (NEC). (See “Grounding” on page 26, “Power Dissipation” on
page 28 and “Electrical Noise” on page 27.)
Wiring of any industrial equipment should be done with some consideration for future
troubleshooting and repair. All wiring should be either color coded or tagged with industrial
wire tabs.
