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 damage eyesight.
Before installing or removing the power cable, open the power switch.
Before connecting a power cable, check that its label is correct.
Fuse
If a fuse needs replacing, ensure the new fuse is of the same type and specifications so that the
system runs safely.
Electrostatic Discharge
Static electricity generated by human bodies may damage the electrostatic-sensitive
components on boards, for example, the large-scale integrated (LSI) circuits.
Wear a pair of ESD gloves or a well-grounded ESD wrist strap when touching the device
or handling boards or application-specific integrated circuits (ASICs).
When holding a board, hold its edge without touching any components, especially chips.
Package boards with ESD packaging materials before storing or transporting them.
