OPERATION
Protection Features
Negative Power
The SubMonitor Connect continuously monitors the power passing through the sensors and produces an
alarm or fault if it senses the voltages and currents do not align. Generally, this indicates a mis-wiring in the
system.
Verify that the motor power leads are routed through the sensors going into the top and exiting from the
bottom of the SubMonitor Connect.
Verify the power lead passing through the phase A sensor is the same connecting to the L1 input terminal,
phase B is connected to L2, and phase C is connected to L3. If external CTs are installed, verify their
orientation as well.
