Note:
1.) All Digital Compressors Must Have The Cooling
Output Voltage Configured For 1.5-5 VDC. This
Voltage Output Must Be Configured When You Are
Setting Up The SA Controller’(s) Operating
Parameters.
2.) All Digital Scroll Compressors Used On The SA
Controller Must Have (1) Relay Output Configured
Per Compressor On The SA Controller In Order To
Enable The Modulating Cooling Device's Sequence.
This Relay Output Must Be Configured When Setting
Up The SA Controller Operating Parameters.

Modulating Cooling Device Wiring
Warning: It is very important to be certain that all wiring is
correct as shown in the wiring diagram below. Failure to observe the
correct polarity could result in damage to the Modulating Cooling
Device or the SA Expansion Module.
