Signal Name

Signal Description

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.

SHREF

Shunt Reference signal to be placed in the DC potential of which the

shunt resides to reference the shunt measurement

SHUNT+

Positive Battery Shunt input signal whose signal polarity is defined by

the voltage on the shunt during battery discharge.

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.

NE_CM

Infinity NE Common or Discharge Ground (DG) connection used for

power and voltage monitoring. Connection made to NEcommon in the

Infinity system.

Discharge Battery (BAT) power input connected to the Non-Grounded

side of the DC bus. Also used as sense voltage for backup monitoring.

SHUNT-

Negative Battery Shunt input signal whose signal polarity is defined

by the voltage on the shunt during battery discharge
