Make sure that the input voltage matches the value specified on the label of the switch.
Place the switch in a well-ventilated and dry environment.
Do not remove the housing of the switch.
Disconnect the switch from the power supply before cleaning it. Do not scrub the switch with any liquid.

permission of the local agent, otherwise you shall be responsible for any damage.
Environmental Requirements
Temperature and Humidity
For the temperature and humidity requirements, refer to “Appendix Technical Specifications”.
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, workbench or subrack where the switch is mounted and receptacle in the wall are all
properly grounded.
