Appendix A Installation of Lightning Arrester for

AC Power (Lightning Protection Grounding Strip)

Caution:

No lightning arrester is shipped with the switch. You should purchase a lightning

arrester if needed.

If an outdoor AC power cable should be directly led to the switch, please serially

connect the lightning arrester for AC power (lightning protection grounding strip) before

you plug AC power cable 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

Please check the power supply circuit.

On means that the arrester works normally.

Otherwise, the protection circuit has

been damaged

Caution:

zMake sure that the arrester is well grounded before using the lightning arrester for

power.

zAfter inserting AC power cable connector of switch into the socket of lightning

arrester, if the green LED is on and the red LED does not alarm, the lightning

arrester of power is running and the function of lightning protection has taken effect.

zPay adequate attention if the red LED ison. You should correctly locate the problem,

whether it is caused because the grounding cable of the arrester is not well

grounded or because the live and zero wires are connected in reverse direction.

You may check that in the following way. When the red LED is on, use a multimeter

to examine polarity at the power socket of the arrester. If it is same to that of the

power socket in the equipment room, it means that arrester is not well grounded. If it

is adverse to that of the power socket in the equipment room, it means that the

power socket of the arrester is set to the reverse polarity. In this case, you should

open the power socket of arrester to correct polarity. After that, if the red LED still

alarms, it means that the arrester is not well grounded yet.
