6.4 Parts Replacement

6.4.1 Replacement Requirements

● 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.
