4.3 Emergency Procedures

When the RI-ENERGYFLOW-MODULAR 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.
the Backup switch is only used when a backup load is applied.
