CPS6000 also offers an optional low voltage load disconnect (LVLD) contactor. Non-critical
loads and loads sensitive to low voltages can be connected to the system via the LVLD in the
Distribution Module. CPS6000 disconnects these loads at a set threshold during a battery
discharge. This reduces drain on the batteries and extends reserve time available for critical
loads.
With the Bulk Output Module, a supplementary shelf may be paralleled to the primary shelf
to create a larger plant. Only the primary shelf would contain the system controller. The
supplementary shelf only requires signal connections to the primary shelf, and power
connections to an external distribution panel. The controller can monitor for open protectors,
current from a battery shunt, and monitor and control a low voltage disconnect contactor via
the Remote Distribution Module (RDM).

2-1a and 2-1b are basic block diagrams of the CPS6000 System in a single shelf with a
Distribution Module. Figure 2-2 shows the Bulk Output Module in place of the Distribution
Module.
