Anti-static Precautions
Electrostatic adsorption occurs if dust falls onto the switch, which may cause poor metal contact
that disables the switch to work properly. To prevent this problem, pay attention to the
following:
Keep the air in the ambient environment clean. Regularly perform dedusting.
Make sure that the switch is grounded properly.
Lightning Protection
In thunderstorm weather, a sudden current caused by lightning stroke may damage the switch.
To protect the switch against lightning stroke or strong current:
Make sure that the device, and workbench where the switch is mounted and receptacle in the
wall are all properly grounded.
Connect the cables to the switch properly to avoid generating internal lightning induction.
If outdoor cabling is required, it is advisable to deploy a signal lightning arrester.
Mounting Requirements
Follow the instructions below.
The desktop is stable and sturdy enough.
Place the switch in a clean, dry and well-ventilated environment. Keep at least 10 cm gap on
all sides for cooling.
Do not place any heavy or big object on the switch.
Keep at least 1.5 cm vertical distances between each device while installing it in stack.
2.2 Installation
Place the switch right side up on a large and stable desktop.
2.3 Grounding
Grounding is not only a measure to release the overvoltage and overcurrent caused by lightning
as soon as possible, but also for personal safety. Select the proper method to ground your switch
according to the installation environment.
