COPELAND™ COMPRESSOR ELECTRONICS
FOR COPELAND™ STREAM COMPRESSORS – QUICK INSTALLATION GUIDE
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.

1. Unscrew the 4 screws located in the corners of the compressor terminal box cover and lift off the terminal box
cover.
2. Open the cover of the Copeland Compressor Electronics module to access the terminals.

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.

7. Connect the Copeland Compressor Electronics module cables for the phase monitoring to terminals U/V/W (2
times 3 cables for each winding, grey GR, black BK and brown BN wires), and to the earth PE (pink PK wire).
IMPORTANT
For Stream CO2small and medium compressor models (4MTL-05 to 4MTL-30 & 4MSL-
03 to 4MSL-15), the blue positions 1U, 2V, 3W, 7Z, 8X, 9Y in diagram below must be
considered. The position of the terminals in all the other Stream compressor models
corresponds to the black positions. The factory delivery is correct, DO NOT reverse the
connections.

8. Connect the control circuit phase (L) to terminal 19 (Figure 6).
9. Connect the crankcase heater to terminals 3 and 4, and to earth. The Copeland Compressor Electronics module
controls the crankcase heater directly, so only a crankcase heater with the same power supply as the module
(115 VAC or 230 VAC) can be selected.
