2.2.4 Electrostatic Discharge Damage Prevention
Electrostatic discharge may damage devices and circuits. Improper treatment may caus
e the switch to malfunction completely or discontinuously.
Move or locate the devices according to the measures of electrostatic discharge preven
tion, ensuring the machine box connects the ground.Another measure is to wear the st
atic-proof hand ring.If there is no hand ring, use the metal clip with the metal cable to cl
ip the unpainted metal part of the machine box.In this case, the static is discharged to t
he ground through the metal cable of the clip.You can also discharge the static to the g
round through your body.
3. Requirements for Common Locations
This part describes the requirements for the installation locations.
1. Environment
The switch can be installed on the desk or the cabinet.The location of the machine box
,cabinet planning and indoor cabling are very important for normal system’s function. S
hort distance between devices, bad ventilation and untouchable control plate will cause
maintenance problems, systematic faulty and breakdown.
For location planning and device locating, refer to section 2.3.2 “Location Configuration
Prevention”.
2. Location Configuration Prevention
The following preventive measures assist you to design the proper environment for the
switch.
Make sure that the workshop is well-ventilated, the heat of electrical devices is w
ell-discharged and sufficient air circulation is provided for device cooling.
Avoid to damage devices by following the electrostatic discharge prevention proc
edure.
Put the machine box at the place where cool air can blow off the heat inside the
machine box.Make sure the machine box is sealed because the opened machin
ebox will reverse the cool air flow.
3. Cabinet Configuration
The following content assists you to make aproper cabinet configuration:
Each device on the cabinet gives off heat when it runs.Therefore, the sealed ca
binet must have the heat-discharge outlet and the cooling fan.Do not put the dev
ices too close, avoiding bad ventilation.
When you install the machine box at the open cabinet, prevent the frame of the c
abinet from blocking the airway of the machine box.
