The E-Plex 331BMI battery monitor is an inductive monitor that senses both current and voltage output. The
battery monitor is bi-polar in that the E-PLEX® network reveals if the battery is charging or discharging. Put
the positive battery cable through the center of E-Plex battery monitor and secure it to the cable. Orient the
331BMI’s 1/4 “ terminals away from the battery post for proper current direction indication by the E-Plex®
The 331BMI-01 has a single reference voltage wire for applications that have the battery negative terminal
in common with the E-Plex return. The wire is required to determine the differential. Calibration is provided
through the E-Logic Software.
