Connecting Ac/Dc Power; Wiring Considerations; Typical Sensor Hookup; Typical Quadrature Hookup - Omega DPF78 SERIES User Manual

NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals! The unit has
been designed with an isolated AC input. Thus, polarity is not a concern for the AC input. The chassis is plastic, therefore
earth ground is not used. For D.C. operation, connect + 12V to pin 7 and - D.C. to pin 8.
Connecting the DPF70 Series to Omega Flowmeters and Amplifiers:
FTB4605 & FTB4607 Water Meters:
DO NOT USE PIN 7 WITH THESE METERS!
