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 the lightning
arrester of power is running and the function of lightning protection has taken effect.
Pay adequate attention if the red LED is on. You should correctly locate the problem,
whether it is caused because the ground wire 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.
