2-2 Installation Recommendations
It is recommended that all signal wiring be shielded wiring or twisted pairs.
Do not install capacitors to correct the power factor between the reduced voltage starter output and
the motor.
Relays and contactors located in the same housing as the reduced voltage starter should have an RC
suppressor parallel to the coil (or a reverse diode, if controlled by DC).
