controller also provides data acquisition, system alarm
management, and advanced battery and energy
management. The controller contains an LCD display
and keypad for local access. The controller provides an
Ethernet port and comes with comprehensive webpages
for remote access. The controller has SNMP capability for
remote system management. The controller supports
software upgrade via its USB port and the WEB interface.
The controller also provides output bus insulation
detection which provides an indication of DC ground
fault. Refer to the ACU+ controller instructions
(UM1M820NNB-2) for more information.
Distribution Section
This section can contain DC output breakers in various
configurations using the following panels.
•
Load Distribution Panel (List 21HA): Provides sixteen (16)
circuit breaker positions (15A to 100A).
•
Bulk Distribution Panel (List 23HA): Provides one (1) 400A
circuit breaker for bulk load distribution.
Note:
The Power Module/Bay may contain either one (1) List
21HA or up to three (3) List 23H.
Distribution Module/Bay (List 07)
A stand-alone Distribution Module/Bay is available.
The Distribution Module/Bay consists of the following
components. All Distribution Module/Bay components are factory
installed in the selected rack.
•
Load Distribution Panel (List 21HA): One (1) or two (2)
List 21HA load distribution panels can be installed in the
Distribution Module/Bay. When the Distribution
Module/Bay is populated with two (2) load distribution
panels, each panel can receive a separate input feed or
the panels can be interconnected for a single feed per
module. Each panel provides sixteen (16) circuit breaker
positions (15A to 100A).
Battery Options
The system may contain up to four (4) battery strings. The short
circuit current generated by the battery option cannot exceed
25kAIC.
•
Emerson Provided Battery Cabinet
Emerson offers a choice of battery models factory
installed and connected in a cabinet (List 90, 91, 92, 93).
Each Battery Cabinet houses one (1) 400V battery string
consisting of twenty-eight (28) 12V battery blocks (336V
nominal). Refer to the Battery Cabinet instructions
(IM58400120090) for more information.
Note:
The maximum short circuit capacity of the circuit
breakers in the system is 25kAIC. Therefore, the
maximum number of Emerson provided Battery
Cabinets is limited to a maximum of three (3). The
use of a fourth Battery Cabinet will exceed the short
circuit rating of the circuit breakers in the system.
•
Customer Provided Batteries
Customer battery solutions must utilize a compatible
battery breaker (see SAG584001200 for specifications).
The short circuit current generated by customer provided
battery option cannot exceed 25kAIC.
HRMG (High Resistance Midpoint Ground)
Configuration (+/- 200V DC)
The HRMG configuration provides system voltages to ground at
half of the output system voltage, for additional personnel safety.
That is, the HRMG version of 400V DC pr/-200V DC to
ground potentials. This configuration is used in applications where
an internal high resistance path is required between the positive
output busbar and site ground and also the negative output
busbar and site ground.
The DC bus is continuously monitored for ground fault conditions.
If the insulation resistance between the +BUS or -BUS to ground
goes below a set value, a ground fault alarm is generated and an
alarm LED located on the front of the Power Module/Bay’s power
and control section illuminates.
