7. Connect the ground cable, power cable and communication cable between PCS and battery rack .
Figure 5-10
5.5 System turns on
Warning: Double check all the power cables and communication cables. Make sure the voltage of the inverter/PCS
is same level with the battery system before connection. Check all the power switches are OFF.
System turns on step:
1) Check all cables are connected correctly. Check grounding is connected.
2) If necessary, turn on the switch at inverter`s battery side or between inverter and battery. If possible, turn on
AC or PV power source to wake up inverter.
3) Open protect cover of Power switch. And turn on power switch.
4) Switch all the battery racks’Isolating Switch to on position.
5) Press the battery STARTbutton in turn, turn on the START metal button of the slave battery firstly, and
finally turn on the START button of the master battery (1 master battery rack and 7 slave battery racks at most
can be configured).
6) If no alarm ,the battery system will be ready for charging and discharge with PCS

20 / 23
5.6 System turns off
When failure or before service, must turn the battery storage system off:
1) Turn off inverter or power supply on DC side.
2) Turn off the switch between PCS and battery system.
3) Switch Isolating Switch to off position. (Switch off the slave battery firstly, finally switch off the master
battery)
Note
1) One battery system shall just have one master, all the others are slaves. (The one on the extreme
side connectedto inverter is the masterbattery.)
2) It is forbidden to switch off the Isolating Switch during charging and discharging.
6.Emergency Situations
6.1 Battery Leakage
If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas. If one is exposed to the
leaked substance, immediately perform the actions described below
1) Inhalation: Evacuate contaminated area and seek medical aid.
2) Contact with eyes: Rinse eyes with flowing water for 15 minutes and seek medical aid.
3) Contact with skin: Wash affected area thoroughly with soap water and seek medical aid.
Ingestion: Induce vomiting and seek medical aid.
6.2 On Fire
NO WATER!
Only dry powder fire or carbon dioxide extinguisher can be used; if possible, move the battery module to a
safe area before it catches fire.
6.3 Wet Batteries
If the module is wet or submerged in water, do not let people access it, then contact FAR EAST BATTERY or an
authorized dealer for technical support. Cut off all power switch on inverter side.
6.4 Damaged Batteries
Damaged batteries are dangerous and must be handled with utmost care. They are not fit for use and may pose
a danger to people or property. If the module seems to be damaged, pack it in its original container, then return
it to authorized dealer.
Warning
Damaged batteries may leak electrolyte or produce flammable gas.
