4.2.2 23" Power Center
Provides up to 26 breakers which can be configured as all load breakers (26 load breakers) or a mix of load and bat-
tery breakers (21 load breakers and 5 battery breakers).
The all load breaker configuration has a shunt that monitors the total load current supplied by the rectifiers to the
load.
The load and battery configuration has a shunt that monitors the total battery charge / discharge current and in-
cludes a Low Voltage Battery Disconnect (LVBD).
Both the hot and return connections are made on ¼" studs on 5/8" centers using narrow tongue lugs. Adapter kits
for landing larger cables are available when higher capacity 2 or 3 pole breakers are required.
4.2.3 Control and Monitoring Methods
The E3 front panel provides inputs and outputs for load and battery voltage, battery or load current, breaker alarms
and disconnect control as well as monitoring. Additional I/O (expansion) is available for customer use. See the table
below for the details.

4.2.4 Breaker Labelling
For systems with load only outputs, the numbering goes from left (1) to right ( 21 for a 19" or 26 for a 23")
For systems with batteries and loads the load numbering goes from left (1) to center/right (16 for a 19" or 21 for a 23")
AND the battery labelling goes from right (1) to left (5).
There is a label on top of the front door which can be seen from the top when the door is closed, and from the front
when the door is open. This label is larger and suitable for writing information about the breaker position.
There are two additional labels for breaker identification: a thin label above the breaker which can be read from the
front (not writable), and one on the back/top near the return breakers which identify the positions of the return (not
writable).
