3.3 Emergency Procedure

When the SMILE5 energy storage system appears to be running abnormally, you can
turn off the grid-connected main switch that directly feeding the BESS, and turn off all
load switches within the BESS, turn off the battery switch at the same time. To prevent a
potentially fatal personal injury, if you want to repair or open the machine after the
power is switched off, please measure the voltage at the input terminals with a suitably
calibrated voltage tester.
Before working on this equipment, please confirm that there is no grid electric supply to
the BESS!
The upper cover plate cannot be opened until the DC-link capacitance inside the battery
modules discharges completely about 15 minutes later.
3.3.1 Emergency Handling Plan
1. Disconnect the AC breaker.
2. Check the control power supply. If it is OK, return the power supply to find out the
reason.
3. Please record every detail related to the fault, so AlphaESS can analyse and solve the
fault. Any operation of equipment during a fault is strictly forbidden, please contact
Alpha as soon as possible.

4. As battery cells contains a little Oxygen inside and all cells have got explosion-proof
2
valves, explosion hardly happens.
5. When the indicator light on the battery shows a red fault, check the fault type through
the communication protocol, and contact our after-sales service personnel for advice.
