1 Plant Interface Connector
J1 is a 6-pin connector provided for interfacing inputs required for basic plant operation in specific
system configurations. These inputs include a single plant shunt, (2) distribution alarms, and open
battery string alarm. J1 connections are typically made in the factory with a specific wire harness
for a given system. Following is a brief description of the inputs.
Pin Signal
Name Description
1 Shunt+ Shunt + is the more positive lead from a system battery or load shunt.
For battery shunts, this is the most positive lead of shunt during a
discharge. The shunt may reside in the grounded or non-grounded side
of the DC bus (±24V/-48V) as long as the Shunt Reference lead is
connected correctly. This lead must comply with Class II wiring
standards.
2 Shunt
Reference
This signal is used to reference the shunt analog measurement circuits to
either the battery or ground side of a system. The reference must be
attached to the same potential or side that the monitored shunt resides.
This lead must comply with Class II wiring standards.
3 Shunt- Shunt - is the more negative lead from a system battery or load shunt.
For battery shunts, this is the most negative lead of shunt during a
discharge. The shunt may reside in the grounded or non-grounded side
of the DC bus (±24V/-48V). This lead must comply with class II wiring.
4 Fuse Alarm
Major - 24V
FAJ1 is the input monitor for distribution that accepts a contact to
Battery for ±24V DC systems as an alarm. Factory default for FAJ1 is to
alarm on application of DC bus voltage. Can be reconfigured as needed
through the web interface.
5 Open String OS1 is the input monitor that accepts a contact to Battery for ±24V/-48V
DC systems to identify an open battery string. Factory default for OS1 is
to alarm on application of DC bus voltage. Can be reconfigured as
needed through the web interface.
6 Fuse Alarm
Major -48V FAJ2 is the input monitor for that accepts a contact to Battery for -48V
DC systems as an alarm. Factory default for FAJ2 is to alarm on
application of DC bus voltage. Can be reconfigured as needed through
the web interface.
