The Copeland™ Compressor Electronics module (previously Next Generation CoreSense) is located in the Stream
compressor terminal box. It is prewired to the oil pressure sensor (for compressors with an oil pump), the motor
thermistor chain (PTC), the discharge temperature sensor and the current sensor.

3. Supply 115 V or 230 V power (N and L1) to the module on extreme left terminals 1 and 2 (both polarities are
possible).
4. Position the jumpers according to starting method and motor type. The jumper position is given on the compressor
wiring diagram.
5. Connect the power supply to the terminal plate.
6. Caution! For part-winding, the power leads from the same phase should go through the current sensor in the
same direction.
