A 85-264VAC is supplied directly to each of the rectiers which produce a nominal +12VDC
output.
B Following a current shunt to measure the rectier current, the rectier DC output is fed
to the battery terminals via a current battery current shunt and a 100A circuit breaker.
C The rectier DC output is also fed to the loads via the LVD (Low Voltage Disconnect,
and 5 circuit breakers.
D The management unit monitors and controls the rectiers via an I²C interface and also
checks the status of the DC load and battery breakers.
E The management unit monitors external sensors and provides alarms.
F This unit incorporates an external temperature shutdown feature which is enabled on
the controller site installation web page (see section 13.4).
If the temperature at the external temperature sense point goes below -10°C or above
+65°C a shutdown sequence is initiated. Once the external temperature returns to
within these limits the system initiates an automatic restart sequence.
