LIGHTNING PROTECTION OF THE

A SWITCH

Installation of

Lightning Arrester for

AC Power (Socket

Strip with Lightning

Protection)

c 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.

Grounding and polarity indicator (red) :

On means that the lines are wrongly connected

(either the ground wire is not well connected, or the live and zero lines are wrongly connected). Please check the power supply circuit.

Power switch

Normal operation indicator (green):

On means that the arrester works normally. Otherwise, it means that the protection circuit has been damaged.

Power socket (complied with IEC standard), connected to the power supply of the equipment through power cord

c CAUTION:

■Make sure that the arrester is well grounded before using the lightning arrester for power.

■After inserting AC power cord plug of switch into the socket of lightning arrester, if the green LED is on and the red LED does not alarm, it means that
