Step 6 With the M6 bolt, secure the OT terminal to the wiring hole.
Step 7 When wiring is complete, gently tug on the cables to ensure that there is margin, and tie
off the cables with cable ties according to the alignment path.
5.7 Signal terminal wiring
There are signal terminals on the energy storage cabinet and no external wiring port on the
battery cabinet, which are mainly used for IO signal transmission, CAN communication, 485
communication, 24V power supply and voltage sampling signal transmission. There is a difference
in the number and definition of external interfaces between the integrated CSU and the non-
integrated CSU of the energy storage cabinet, the field should be wired according to the actual
configuration and refer to the following interface definition table, and the wiring of external
interfaces of the energy storage cabinet is shown in the figure below.
