Signal Description
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
J2
Provides the contactor management interface for control and LVD status.

Pin # Signal Name Signal Description
1 LVD_COILA
Low Voltage Disconnect Coil Voltage A. “A” positive with respect to “B” to
close contactor. Signal connected to one side of contactor coil.
2 LVD_C Common of contactor status indicator. Connect signal to Common of the
micro-switch of contactor. Return reference for LVD auxiliary alarm status
detection.
3 LVD_NO Normally Open contactor status monitor indicator. Closed to LVD_C when
contactor is closed. Connect signal to NO pin of micro-switch of contactor.
4 LVD_COILB
Low Voltage Disconnect Coil Voltage B. “B” positive with respect to “A” to
open contactor. Signal connected to other side of contactor coil.
5
BATT_SNS
Reserve Battery Sense Voltage input signal. Battery bus voltage used for
reverse battery detection. Connection made to battery side of the battery
contactor. Signal connection must not be used for Load contactors.
6 LVD _NC Normally Closed contactor status monitor. Closed to LVD_C when contactor
is open. Connect signal to NC pin of micro- switch of Contactor.
TB1
Terminal Block connection that provides field access to Fuse Alarm Major, Open String, and the Remote LVD
input.

contact closure input signal.
2 Remote LVD External contact closure for remote disconnecting attached LVD; Disconnects
LVD on a dry contact closure to Remote LVD Return when feature is enabled.
3 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 connector J1.
4 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 connector J1.
