A.1 Installation of Lightning Arrester for AC Power (Socket
Strip with Lightning Protection)
Caution:
Lightning arrester will not be shipped with the switch. You should purchase it by
yourself if needed.
If an outdoor AC power cord should be directly led to the switch, please serially connect
the lightning arrester for AC power (Socket Strip with Lightning Protection) before you
plug AC power cord into the switch, thus to prevent the possible damage to the switch
due to lightning strike. You can use cable clips and screws to fasten the lightning
arrester for AC power on the cabinet, workbench or the wall of equipment room.
Normal operation indicator (green):
On means that the arrester works normally. Otherwise, it
means that the protection circuit has been damaged.
