INSTALLATION INSTRUCTIONS FOR SYMCOM’S
MOTORSAVER®MODEL 460
BE SURE POWER IS DISCONNECTED PRIOR TO INSTALLATION!!
FOLLOW NATIONAL, STATE AND LOCAL CODES!
CONNECTIONS
1. Mount the MOTORSAVER®in a convenient location in or near the motor control panel. If the
location is wet or dusty, then the MOTORSAVER®should be mounted in a NEMA 4 or 12
enclosure. The 460 can be mounted to a back panel using two #6 or #8 x 5/8 screws or can be
snapped on to a DIN rail.
2. Connect L1, L2 and L3 on the MotorSaver’s terminal strip to the LINE SIDE of the motor starter.
(See Figure No. 1).
3. Connect the output relay to the circuitry to be controlled. Connect the normally open contact in
series with the magnetic coil of the motor starter as shown in Figure No. 1 for motor control.
Connect normally closed contact in control circuit as shown in figure No. 2 for alarm operation.

SETTINGS
1. LINE VOLTAGE ADJUSTMENT:Rotate the LINE VOLTAGE
ADJUSTMENT to the nominal three-phase line voltage
feeding the motor to be protected. The Model 460 will
automatically sense whether it is connected to a 200V or
400V 60 Hz or 380V - 416V 50Hz power system.
2. RESTARTdelay: Rotate the RESTART delay to the
desired position. The restart delay is the time between the
MOTORSAVER®seeing acceptable power and the
MOTORSAVER®closing its output contacts. For compressor
applications, the restart delay should be set for the
approximate time it takes for the head pressure to bleed
off of the compressor. For other applications, the restart
delay is typically set at 2 seconds.
(NOTE: This delay is also the minimum cycle time or rapid
cycle timer for the motor or compressor when control power
is lost such as the operation of a Thermostat.)
3. UNBALANCE TRIP: Rotate the UNBALANCE TRIP to the
desired voltage unbalance trip level. The NEMA MG1
standard does not recommend operating a motor above a
1% voltage unbalance as determined by the following formula
without derating the motor.
% Voltage Unbalance = [(Maximum Deviation from the Average) / Average] x 100%
The NEMA MG1 standard also recommends against operating a motor above a 5% voltage unbalance
under any circumstances. Therefore, a 5% setting on "UB" is a good place to start but SymCom
recommends consulting the motor manufacturer for specific tolerances.
4. TRIP DELAYADJUSTMENT:Rotate the TRIP DELAY ADJUSTMENT to the desired setting.
The adjustment does not affect the trip delay on a single-phasing fault. Typically, the TRIP DELAY
ADJUSTMENT is set to 4 seconds. In areas where voltage fluctuations are frequent, the TRIP DELAY
ADJUSTMENT may be set between 10 and 20 seconds.
POWER-UP
Turn on the power to the motor. The green RUN LIGHT will blink during the RESTART delay.
After the RESTART delay, the MOTORSAVER®will energize its output contacts and the green RUN
LIGHT will light. If the contacts do not energize and the RUN LIGHT does not light, then see the
TROUBLESHOOTING section.
