Chapter Installation & Wiring Typical Connection Figure 2.9 shows a typical connection diagram for use in a retrofit application. In for Retrofit this scheme, the controller provides control of the load when the electromechanical starter is energized. This method of controlling the load can be used in applications Application where the existing control scheme is to remain intact. - Page 10 Chapter Installation and Wiring Typical Connection Figure 2.11 shows a typical connection diagram for use with a shunt trip circuit with Shunt Trip breaker. In this scheme, the electromechanical contactor is eliminated. The shunt trip circuit breaker provides automatic isolation from the main power lines during Circuit Breaker abnormal conditions and can also be used to provide a manual isolation from the main power lines.
- Page 11 Chapter Installation & Wiring Power Factor The controller can be installed on a system with power factor correction capacitors. Capacitors The capacitors must be located on the line side of the controller. This must be done to prevent damage to the SCRs in the SMC PLUS controller. When discharged, a capacitor has essentially zero impedance.

Chapter Set-up Procedures: SMP PLUS Controller without Options Line Fault The line fault indicates an abnormal condition has been sensed in the line. Conditions which will cause line fault indications are phase loss, open motor lead and shorted SCR. If detected in either the “Starting” or “Running” modes, the controller trips and the FAULT and LINE LEDs light. -
