3, then the reverse battery protection feature will be provided. Read all warning statements prior to
making any connections.
• Manual LVD Cont Connect - Manual LVD Contactor Connect. This feature allows the CPS6000 system
to resume powering the load after low voltage disconnect of batteries following a battery on discharge
event. The fully depleted battery strings are to be replaced with fully charged strings. Once the strings
have been replaced, depressing the Manual LVD Cont switches on the front of the ES772A module will
result in the LVD contactors closing and the LED blinking in green color. Continue to depress the
switches until the LED stops flashing and displays a continuous green color. This indicates acceptance
of command and continued closure of contactors. Note that releasing the switches prior to the LED
displaying a continuous green color will result in the contactor opening and removing power to the
load.
• External battery shunt input, (J1, pins 4 and 11). The battery shunt must be in the VBatt(-) leg to
maintain proper reference with the ES772A module. These inputs are for the system controller to read
battery current. The polarity of the connections must be positive during battery discharge.
• Monitor plant voltage for backup LVD function (in case of failure of controller during battery
discharge)
Module Connector Definitions
The ES772A module has five connectors. Two are RJ-45 connectors used for RS485 serial communication to
ES773A VT-Probes, the ES771A Remote Voltage Monitoring Module, and to the controller. The remaining
connectors are used for monitoring circuit breakers, contactors and shunts and are defined in the following
tables.
