● It is recommended that you install the battery temperature sensor (secured with an

adhesive) on the surface of batteries in the middle of the battery rack.

● Check the upstream input power cable connection. If the PE wire and neutral wire are

short-circuited, the system is a TN-C system. If the PE wire and neutral wire are

connected separately, the system is a TN-S system.
