Omega DPF78 Connecting AC / DC Power Wiring Considerations, Do not USE PIN 7 with These Meters

CONNECTING AC / DC POWER

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.
