Feedback and reference potentiometer circuits are not isolated from main power. Isolation transformers are mandatory for tachometer feedback operation using a type RE020 20.8 VDC/1000 RPM tachometer (Model R20E8000). Consult instruction manual D2-3231 for other recommended or mandatory uses of isolation transformers and complete application information.
