2.2 Distribution panel
2.2.1 Distribution configurations
The distribution panel contains 14 x 1RU type plug-in breaker positions. Each breaker position has two-hole
connection points, one for the breaker output and another one for the ground return bus. The distribution panel
has 4 breaker positions for the batteries and 10 breaker positions for the loads.
Load breakers require compact 1RU plug-in breakers without auxiliary switch while battery breakers require
compact 1RU plug-in breakers with auxiliary switch.
2.2.2 Low voltage battery disconnect (LVBD)
An optional 225A low voltage disconnect (LVD) can be ordered and factory installed in series with the batteries.
This is called a low voltage battery disconnect (LVBD).
2.2.3 Shunt
A 200A shunt is installed in series with the batteries for current measurements. The controller automatically
calculates the load current.
2.2.4 Internal alarm card
The distribution panel includes an alarm card, a low voltage disconnect override switch, a breaker trip LED
indicator and a breaker inventory push button.
The alarm card provides terminal block access to internal signals such as binary alarms for breaker trips and
LVDs, alarm relays for driving the LVDs, and analog inputs for current (shunt) and voltage measurements. The
terminal block provides a single access point between these signals and an external system controller. Refer to
the customer connections (“–08”) drawing at the rear of this manual for details on terminal block assignments.
The LVD override switch allows the user to override the LVD during controller maintenance. A green LED
illuminates when the LVD is operating normally. A yellow LED illuminates when the LVD is in the override
position.
