Before removing or installing the power cable, turn off the power switch.
Before connecting a power cable, check that the label on the power cable is correct.
During the installation of AC power supply facilities, follow the local safety regulations.
When operating the high-voltage and AC-powered facilities, use dedicated tools.
Ensure that a spare component is the same model as the faulty one is prepared before
replacing the faulty component.
Do not install or remove power cables when the device is on. Transient contact between
the core of the power cable and the conductor may generate electric arcs or sparks, which
may cause fire or hurt eyes.
Before removing cables from a faulty component, mark the cables with their
corresponding ports numbers for later connection (confirm by referring to the electrical
conceptual diagram).
Ensure that the cables are connected to the spare component properly.
A component in the electric control box needs to be replaced.
