the battery: the battery power terminal is on the right side of the chassis), tighten it with 4 M6*12

Before the front panel of the box is locked, the battery must be in the starting state. It is
recommended to turn on all the battery power buttons first, and then press SW button when
the parallel box of the last box is locked to avoid shutting down the box after sealing it.
1. Hang the front panel on the two l-shaped brackets at the upper end of the box (as shown in
Figure8). After hanging the front panel, push it down to avoid improper installation of the front
panel (as shown in Figure 9).
2.Press and hold the front panel of the box body by hand to compress the sealing bar to
ensure the matching of the hole position of the cross screws. Use the cross screwdriver to
tighten the 6 M4 countersunk screws (as shown in Figure 10).
3. Lock all M4 countersunk head screws once to complete installation
