Connector Definitions
The NE872 module has six connectors used for board power, measurement, alarm inputs and
various serial communications.
J1 Provides the connections to external distribution module’s bus voltage and power,
shunt inputs and reference, Fuse Alarm Major And Open String Inputs.
Pin # Signal Name Signal Description
1 FAJ General purpose Fuse Alarm Major (FAJ) alarm input; Major alarm on
closure to the non-grounded “Battery” side of the DC bus (-
48V/±24V). Optional connection at terminal block TB1.
2 NC
3 SHREF Shunt Reference signal to be placed in the DC potential of which the
shunt resides to reference the shunt measurement
4 SHUNT+ Positive Battery Shunt input signal whose signal polarity is defined by
the voltage on the shunt during battery discharge.
5 OS Open String (OS) alarm input for external battery disconnect switch;
Alarms on closure to the non-grounded “Battery” side of the DC bus (-
48V/±24V). Optional connection at terminal block TB1.
6 NE_CM Infinity NE Common or Discharge Ground (DG) connection used for
power and voltage monitoring. Connection made to NEcommon in the
Infinity system.
7 DB Discharge Battery (BAT) power input connected to the Non-Grounded
side of the DC bus. Also used as sense voltage for backup monitoring.
8 SHUNT- Negative Battery Shunt input signal whose signal polarity is defined
by the voltage on the shunt during battery discharge
