    Battery module parallel operation spacing diagram： 5.2.2 Unpacking order First open the box of System Power Distribute Unit, take out the base and handle. The handle is used to carry the battery module, without the handle the battery module will be difficult to re- move from the battery box.
  • Page 15 ii. Open the battery box, take a battery module out. Hold the handle of both batteries with your hands easy for lifting. Put one battery module on the base. Insert the plug on the base into the port on the battery. Pay attention to the direction of the mod- ule to make sure that the blind-mating connectors of the module and the base are at the same side.
  • Page 16 v. After all battery modules are stacked, put the PDU on top of the battery modules. vi.Fix the connection between the battery module and the base, between battery modules, and between PDU and battery module with screws (M4*6). To do this, use a Phillips screwdriver to tighten the screws through the holes on them.
