B. System turns on
Double check all the power cables and communication cables. Make sure the voltage of the
PCS is same level with the battery system.
(1) Switch the external power or PCS on, to sure all the power equipments can work normally.
(2) Turn the BMSs (Battery Control Modules) on, to supply 12VDC power to BMCU (3

battery string work normally or not.
Battery sting turns on:
Turn on the "POWER" switch;

The battery string's system will check itself, if work normal the battery string system will

goes into standby mode. The Power Relays in BMS will act. BMS and BMCU will light green
of the "STATUS" lamp; If they shows orange or red, it means has failure in the system, must
debug at first.
Note: External Power should communicate with battery system through CAN or RS485.
Otherwise maybe cause battery system work abnormal.
C. System turn off
When failure or before service, must turn the battery system off:
(1) Turn off the power switch of external power or PCS.
(2) Turn off the high voltage DC Power Switch.
(3) Turn off the BMS's power Switch.
Caution: the BMS, which 12VDC power supply to BMCU, must turn off at last.
Caution:
Before change the battery module for service, must charge/discharge the replaced battery
