Wiring AC Power (typical 480 V, 3-wire transformer)
Motor Starter Outputs
1. Connect control power to the STR_PWR terminal (P1-24).
2. Connect the MTR1_STR terminal (P1-23) through a 1 A slow-blow fuse to the coil of the motor starter or the control
relay designated as Pump 1. (This fuse protects the TCU relays from short-circuited coils).
3. Connect the other side of the motor starter coil through appropriate disabling contacts to control power neutral. Make
similar connections for Pump 2 and Pump 3 for duplex and triplex stations.
When the alternator function is disabled through the TCU’s configuration, MTR1_STR controls the Lead pump, MTR2_
STR controls the Lag pump, and MTR3_STR controls the Lag2 pump. They should be wired accordingly.
