5.3.2 Battery Cabinet Door Inspection
1. When the small door is open, check from the electrical compartment side whether the upper and lower connecting rod
pulleys on the inside of the cabinet door have slid into the welding pin seat of the cabinet.
2. Check from the electrical compartment side for an overlapping area between the lock tongue on the inside of the cabinet
door and the welding socket of the cabinet.
3. If it is difficult to observe the points outlined in steps 1 and 2, you can directly observe from the side whether there are
obvious protrusions at the two yellow circles (as shown in Figure 5-6).
4. If it is possible that the connecting rod pulley has not been inserted into the cabinet welding pin seat, open the door and
close it again using the instructions in Section 5.6.1.1.

WARNING:
 Ensure permission is granted from the local utility company BEFORE connecting to the AC side of the unit
to the utility grid.
 Contact with live components can cause fatal electric shock! Make sure the AC source is
disconnected and the contact terminals are not energized.
 Incorrect AC side wiring can cause severe system failure and possible damage.
 Wiring instructions for inside the ESS must be strictly followed, and the phase sequence of the power grid
must be correct.
