Check Connection Cable
Before electrical connections, check all cables for insulation and intactness. Poor
insulated or partially bare cables or cables with other damages will pose a serious
safety risk, and need to be replaced immediately.

Cable Connection Precautions
Before cable connections, make sure the polarities of the DC cables are correct
and the connection sequences of the AC cables are consistent.
During electrical connection, do not forcibly pull any wires or cables, as this
may compromise the insulation performance.
All cables and wires should be bent to some extent.
Take necessary auxiliary measures to reduce the stress applied to the cables or
wires.
After completing each step, carefully check the connection for correctness and
firmness.
