Fig 4.8: Power connection
Note:
1) The battery is not allowed to be wired in the running state, and the RUN lights of the
battery module should all be off before installation.
2) Please install the communication line first, then plug the unused RJ45 port and USB
port with a dust cover, and finally install the power line.
3) To ensure the safety of the system, do not forget to ground the ground wire.
4) We recommend installing a circuit breaker between the PCS and the battery. For the
specifications of the circuit breaker, we recommend using a molded case circuit breaker
with a rated operating voltage greater than 80Vdc and a rated operating current greater
than 200A.
5) No cable connection required between battery packs in a single battery cluster.

Fig 4.10: Multi-cluster communication wiring
Note:
1) Refer to Figure 13 for power line wiring.
2) The power combiner box needs to be prepared by the user.
3) Please install the communication line first, then plug the unused communication port
and USB port with a dust cover, and finally install the power line.
4) We recommend installing a circuit breaker between the PCS and each cluster.. For the
specifications of the circuit breaker, we recommend using a molded case circuit breaker
with a rated operating voltage greater than 80Vdc and a rated operating current greater
than 200A.
