Make sure that the AC input MCBs, rectifier MCBs and load MCBs are switched off. Make sure that all the devices are properly
installed.

Check that the earth cables of the cabinets are connected reliably and that the wiring and screws in the cabinet are fastened
Open all the MCBs in the AC distribution cabinet, and then feed the mains supply to the system, measure the phase voltage of
the three phases with a multimeter to confirm the mains condition. If everything is normal, proceed with the next step
Turn on the AC input MCB of the AC distribution cabinet, the run indicator of the AC distribution cabinet should illuminate
Close the MCB of the AC distribution cabinet corresponds to the rectifier cabinet, the power indicator of the rectifier cabinet
should illuminate

Comments
After introducing the AC mains, turn on one certain MCB of rectifier in the upper part of the rectifier cabinet. The power
indicator of the corresponding rectifier should be on and the fan begins to run
After a while, the controller will display 378.V output voltage
Turn off the MCB of this rectifier, and check the other rectifiers one by one through turning on and off the rectifier MCBs and
see if they can work normally.

Preliminary Test of Controller
Check Item
Ok
Comments
After the controller is powered on, it will do self-test without needing any operation. After about 50s, the M822E should start
and display the main screen, and the first screen of the controller see
M822E Controller User Manual
The first screen of M822E is the language selection screen. You can select English or other local language and then enter
default interface. It will enter the default interface directly after 30s without any operation

Preliminary Test of DC Distribution and Battery Connection

Comments
Measure the battery voltage with multimeter and keep a record.
U=
Turn on one rectifier, and set the rectifier voltage to a value with less than 0.5 V difference from the battery voltage through
the controller.
Use insulated tools, and connects the battery cables to the battery I and battery II according to the instructions of the battery
manufacturer. The other end of the battery cables has already been connected to the battery fuse as required in
Connection
of battery cables
Set the power supply voltage to the required battery float voltage through the controller (in this case, the rectifier should not
be in current limiting state).
DANGER!
Before access the battery, check with a multimeter that the battery polarities are correct. When connecting
the battery, careful attention is required to prevent short circuit of the positive and negative poles of the battery. If two
batteries are connected at one time, battery mutual charging due to unequal terminal voltages of the two batteries
should be avoided.
