Note 5: If battery disconnect units (BDUs) are used on the new or Existing Power
System, these shall be wired in such a way as to be all triggered
simultaneously in order to prevent any overloading of these.
Note 6: For the size and number of bridge cables between the two power systems,
take into consideration the voltage drop, the available connecting points in
each system, as well as the fact that these cables are unfused and shall
therefore be run on a dedicated cable rack. “C” or “H” taps may be used to
make full use of available connecting points.
Note 7: The legacy system retains the function of its controller and the percent of
load on each plant is controlled by the MCA. Alarms may be sent
individually from each plant, or combined using an LMS1000 and the
programmable relays resident in the controller.
Note 8: Add a label on both power systems to indicate that these are operating in
the Power Share Mode with each other.
Note 9: The use of an MCA I/O card will allow the user to replace the total load on
the MCA with the reading of a main shunt, such as one in a chandelier
application, or add the reading of load shunt in the legacy plant to the
internally calculated load of the NetSure Power System.
Note 10: The LMS allows the MCA programmable relays to send SNMP traps, and
respond to SNMP gets as well.
Note 11: LMS Function Channel # 64 is dedicated for summing the total current
output of conventional rectifiers in a hybrid application. The channel name
for F64 will default to “Total Rectifier Output.” The LMS updates the MCA
with the calculated value for the configured program line. The MCA looks
for a value on LMS Function Channel #64 and adds that to the internally
calculated total Rectifier load.
