Huawei MTS9300A - 4.3.4 Replacing a Circuit Breaker

Procedure
Step 1 Switch on the lithium battery circuit breaker.
Step 2 Press the Manual ON/OFF button on the lithium battery to activate the lithium
battery.
Step 3 Press the switch for 2–5 seconds. The system is powered on when you hear a
sound from the contactor.
Step 4 Check whether the lithium batteries communicate properly. If the run indicator on
a lithium 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 5 Observe the lithium batteries for 15 minutes. The lithium batteries are running
properly if the alarm indicators are
o.
Step 6 Set all circuit breakers to the appropriate status based on site requirements.
Step 7 Observe the power system for 15 minutes. If no alarm (except the door status
alarm) is generated on the SMU during this period, the current and voltage for
batteries and loads are normal.
