The Model 460-VBM MotorSaver
®
is an auto-ranging voltage monitor designed to protect 3-phase
motors—regardless of size. It can be used on 190–480VAC, 50/60Hz motors to protect from
damage caused by single-phasing, low voltage, high voltage, phase reversal, and voltage
unbalance.
The Model 460-VBM (Voltage Band Monitor) has low and high voltage adjustment knobs and will
only permit motor operation if the voltage is within these limits.
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. The
MotorSaver
®
can be mounted to a back panel using two #6 or #8 x 5/8 screws or can be
snapped onto DIN rail.
2.
Connect L1, L2 and L3 on the MotorSaver’s terminal strip to the LINE SIDE of the motor starter
(see Figure 1).
3.
Connect the output relay to the circuitry to be controlled. For motor control, connect the
normally open contact in series with the magnetic coil of the motor starter as shown in Figure 1.
For alarm operation, connect the normally closed contact in series with the control circuit as in
Figure 2.
