Wiring Practices
The type of wire used and how it is installed for specific applications makes the difference
between obtaining reliable operation and creating additional problems.
Power Wiring
Conductors carrying power to anything (motor, heater, brake coil, or lighting units, for
example) should be contained in conductive conduit that is grounded at both ends.
These power wires must be routed in conduit separately from signal and control wiring.
Control–logic Conductors Typically, operator’s controls (push buttons and switches), relay contacts, limit switches,
PLC I/O’s, operator displays, and relay and contactor coils operate at low current levels.
Therefore, these wires should be routed away from sensitive signal wires and contained
within conduits or bundled away from open power and signal wires.
Analog Signal Wires
Analog signals generally originate from speed and torque controls, plus DC tachometers
and process controllers. Reliability is often improved by the following noise reduction
techniques:
•
Use twisted-pair shielded wires with the shield grounded at the drive end only.
•
Route analog signal wires away from power or control wires (all other wiring
types).
•
Cross power and control wires at right angles (90
°
) to minimize inductive noise
coupling.
