The Model
455
-480R, 3-phase voltage monitor combines line and load-side monitoring to alert the
user of contactor failure. Line-side monitoring will protect the motor from damaging power conditions
including high and low voltage, voltage unbalance, single-phasing, phase reversal and rapid cycling.
The Model 455-480R has a high voltage relay to handle up to 600V control voltage and is now
equip
ped
with an infrared LED to communicate with the hand-held diagnostic tool, the Informer MS
Ed
ition, t
o display trip points, real-time data, and the last 20 faults and 32 motor starts.

S
1.
Mount
the MotorSaver
®
in a convenient location in or near the motor control panel. If the
location is wet or dusty, it should be mounted in a NEMA 4 or 12 enclosure.
2. Connect L1, L2, and L3 on the MotorSaver
®
to the LINE SIDE of the motor starter.
3. Connect M1, M2 and M3 to the power lines on the LOAD SIDE of the motor starter.
NOTE: If a 2-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 load-side protection is not desired, connection to the M terminals is not required—the
Model 455-480R will operate as a line-side only voltage monitor in 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 1.
NOTE: L1 and M1 must be connected to the same supply line as shown. Similarily, L2 and M2, as well as L3 and
M3 must be connected to the same supply lines.
