SymCom’s MotorSaver
®
Model 201A is an auto ranging plug-in voltage / phase monitor designed to
protect 3-phase motors regardless of size. It is used on 190-480 VAC, 50/60 Hz motors to prevent
damage caused by single-phasing, low voltage, phase reversal, or voltage unbalance conditions
(high voltage detection is only available with the Model 201A-9).
CONNECTIONS
1. Locate 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. Mount an 8-pin socket to the motor control back panel (SymCom P/N OT08-PC, sold
separately, is required for UL rating).
3. Connect L1, L2 and L3 (terminals 3, 4 & 5 on the relay socket) to the LINE SIDE of the
motor starter as shown in Figure 1.
4. 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 shown in Figure 2.
5. Plug the MotorSaver
®
into the socket.
