INSTALLATION INSTRUCTIONS
FOR SYMCOM’S MOTORSAVER
MODEL 102600
The Model 102600 is a three-phase voltage monitor designed to protect 600
VAC motors regardless of horsepower. It will protect 50 to 60 Hz motors from
damage caused by single phasing, phase reversal, voltage unbalance, and low
voltage.
CONNECTIONS
1.Mount the MotorSaver® in a convenient location in or near the motor
control panel. If the location is wet or dusty, the MotorSaver® should be
mounted in a NEMA 4 or 12 enclosure.
2.Connect the three lines of the motor’s three-phase power supply to L1, L2,
and L3 on the MotorSaver® (see Figure No. 1).
3.Connect the output relay to the circuitry to be controlled (see Figure No. 1
and Figure No. 2).
A. To control a motor, connect the normally open contact in series with the
magnetic coil of the motor starter as shown in Figure 1.
B. To sound an alarm, connect the normally closed contact in series with the
alarm as shown in Figure 2.

SETTINGS
1.LINE VOLTAGE ADJUSTMENT: Rotate the LINE VOLTAGE ADJUSTMENT to
the nominal three-phase line voltage feeding the motor.
POWER-UP
Turn on the power to the motor. The MotorSaver® then goes through its restart
delay and the LED will flash green (see Table 1). After the restart delay, the
MotorSaver® will energize its output contacts and the RUN LIGHT will turn solid
green. If the contacts do not energize and the RUN LIGHT does not turn solid
green, then see the TROUBLESHOOTING section.
