6.5.2 Installation Of Lower Fender
BD 30-150kW-P inverters have lower fencing boards at the bottom of front, back, left and
right. They are packaged and placed at the bottom of the packaging box. Before installation,
all lower fencing boards of the inverter must be removed and put out. After the inverter is
positioned and the screw is locked, the lower fencing boards shall be installed. Dust-proof
cotton is installed in the lower fencing board, which can not be lost during installation.

6.6DC Side Wiring
6.6.1 Battery Connection
The DC-side connection of batteries connected to this series inverters is shown in Table 6-5
below.
Battery voltage access range is 400V ~ 850V. For a single BD 30-150kW-P inverter, the
power should not exceed 1.05 times the rated power. When connecting, users need to
access at least 50mm² input lines per channel. The energy storage inverter has left many
terminals for users. Refer to Section 6.5 for the access location of copper bars.

6.6.2 The DC Side Wiring Steps Are As Follows:
Step 1:
Verify that all terminals of the inverter have been powered off with a multimeter.
Step 2:
Identify the positive and negative poles of the cable and mark them well.
Step 3:
Connect the positive and negative poles of the battery pack to the "BAT+" and "BAT-
" terminals.
In order to avoid personal and equipment injury, wiring must be carried out without
electricity.
DC switch is off.
Multimeter is used to measure that the DC side wiring row is not live.
DC input voltage limit. Confirm that the DC input voltage should not exceed 850VDC!
