8.3.6 Protection Requirements
Main circuit cable protection requirements
Apply heat‑shrink tubing to the copper lug and conductors of the cable, and ensure
all conducting parts of the cable are properly wrapped, as shown in "

Requirements for upstream protective devices
● Install appropriate protective devices on the power input side to provide
overcurrent, short‑circuit, and isolation protections.
● When selecting protective devices, take the following factors into consideration:
current capacity of the main circuit cable, required system overload capacity, and
short‑circuit capacity of the upstream power input. Generally, select those
recommended in the selection guide for peripheral electrical components.
