User Manual
To avoid damage to batteries, switch on the battery circuit breaker only after correctly setting
the battery parameters.
Procedure
Step 1 Switch on the battery circuit breakers.
Step 2 Check whether the batteries communicate properly. If the run indicator on a battery is steady
on, the battery communicates properly with the monitoring device. If it blinks fast (4 Hz), the
communication between them is interrupted. If so, check whether the communications cable
is properly connected.
Step 3 Observe the batteries for 15 minutes. The batteries are running properly if the alarm indicators
are off.
Step 4 Switch all the circuit breakers to the appropriate status based on site requirements.
Step 5 Observe the power system for 15 minutes. During this period of time, if no alarm (except for
the door status alarm) is generated on the LCD of the SMU, the voltages and currents for
batteries and loads are normal.
