4.1.3 Safety Instructions

Electrical Safety
Danger!
Never connect or disconnect any hot power cables. At the instant when power cables
touch conductors, electric sparks or arcs may occur, which may cause fire or eye injury.
Turn off the power supply before installing or removing a power cable.
Make sure the cables and the cable labels match the practical installation conditions before
connecting them.
Warning!
Do not drill any holes on the cabinet on your own. Improper drilling may damage the wiring
and cables inside the cabinet and the metal scraps produced during the drilling will cause
short circuits in the circuit boards if they enter the cabinet.
Static Electricity
Caution!
The static electricity generated by human body can damage the electrostatic-sensitive
components on the circuit board, such as the large scale integrated circuit (IC).
Accumulated electrostatic charges (ESC) derive from friction created by human body
movements. In a dry environment, the static voltage carried by a human body can be
up to 30 kV, and can remain in the human body for a long time. When an operator who
carries static electricity touches a component, he will discharge electricity through the
component, thus damaging the component.
Before touching any equipment or holding the board, circuit board, and IC chip, wear the
antistatic wrist strap and make the other end of it be well grounded. This helps avoid
damaging electrostatic-sensitive components by the static electricity of human body.
