It also reduces the workload of troubleshooting, reduces the workload of wiring on the construction site, reduces the probability of errors in wiring diagram recognition on the construction site, and simplifies wiring requirements.

[0031] like Figure 5 As shown, in another embodiment, the number of devices in the device group 5 can also be three devices, and the devices are also connected through the foolproof cable 4.

[0032] like Figure 6 As shown, the first fool-proof terminal 41 and the second fool-proof terminal 42 of the fool-proof cable 4 can be different in terminal model, number of terminals, and spacing between the two terminals, ensuring that they can only be connected in the correct way to avoid equipment damage or failure due to connection errors; reduce user errors during operation, thereby reducing the risk of electrical accidents and improving overall safety of use; using the fool-proof cable 4 can reduce equipment failures caused by human errors and improve the overall reliability of the system.

[0033] At least one first adapter seat 11 and a second adapter seat 12 are provided on the wiring adapter plate 1. The wiring adapter plate 1 is connected to the equipment group 5 through the first adapter seat 11 and the second adapter seat 12.
