CONNECTIONS

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. Mount the SymCom P/N OT11 socket to the motor control back panel.

3. Connect L1, L2 and L3 (terminals 5, 6 & 7 on the relay socket) to the LINE SIDE of the motor
starter (Figure 2).

4. Connect the output relays to the circuitry to be controlled. See Figure 1 for pin diagram. The
output relays are isolated, so different control voltages may be applied to each one. For motor
control, connect a normally open contact in series with the magnetic coil of the motor starter as
shown in Figure 2. For alarm operation, connect a normally closed contact in series with the
control circuit as shown in Figure 2.

5. Plug the relay into the relay socket.
