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.
2. Connect L1, L2 and L3 on MotorSaver’s terminal strip to the LINE SIDE of the motor starter.
(See Figure No. 1).
3. Connect M1, M2 and M3 to the power lines on the LOAD SIDE of the motor starter.
(See Figure No. 1)
NOTE: If a two-pole contactor is used, jump the hard-wired line from the L side terminal (the wire
not connected through the contactor) to its corresponding M terminal. If you have any questions,
call SymCom @ 1-800-843-8848.
If load side protection is not desired, connection to the M terminals is not required. The Model 455
will operate as a line side only voltage monitor with this configuration.
4. 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.
