The first screen of M830D is the language selection screen. You can p
ress ▲ or ▼ to select English or other
languages. Then press ENT to enter default interface. It will enter fault interface directly after 30s without any
operation, as the following figure.
Preliminary test of DC distribution and battery connection
Please connect the battery to the system according to the following steps.
1. Measure the battery voltage with multimeter and keep a record.
2. 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.
3. Use insulated tools, and connect the battery cables to the batteries according to the instructions of the battery
manufacturer. The other end of the battery cables have already been connected to the battery fuse as required in
3.3.4 Connecting Battery Cables
Danger
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.
4. 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).
4.3 Setting Basic Parameters
4.3.1 Setting DIP Switch
Note
If users purchase a single DC distribution cabinet, they need to set its address by setting the DIP switch on the SM DU.
Otherwise users do not need to set the DIP switch.
If users purchase a single DC distribution cabinet, they need to set its address by setting bit 1 ~ bit 3 of the S1 DIP
switch on the SM DU. The default address of the DC distribution cabinet is
“1”, users should set the address
according to the practical situation.
Position
“ON” represents “0”, and “OFF” represents “1”. The DIP switch is shown in Figure 4-1.
