Install a power lightning arrester
Note that:
1) Make sure that the protection wire (PE) terminal of the power lightning arrester is
well grounded before using it.
2) After the AC power cord of the firewall is plugged into the multi-purpose socket of
the power lightning arrester (lightning protection busbar), if the green LED is ON
and the red LED is OFF, the lightning protection can function normally.
3) Pay attention and clear the alarm if the red LED is ON. You should correctly tell
whether the grounding cable is not well connected or the live and zero wires are
connected reversely. When the red LED is ON, use a multimeter to examine the
polarity at the multi-purpose socket of the power lightning arrester.
z
If the live and zero wires are on the left and right respectively (supposing that you
are facing the socket), the PE terminal of the power lightning arrester is not
grounded.
z
If the live and zero wires are on the right and left respectively (supposing that you
are facing the socket), the polarity of the power socket of the power lightning
arrester is reversed. In this case, you should open the power socket to correct the
polarity. After that, if the red LED is still ON, you can make sure that the PE
terminal of the power lightning arrester is not grounded.
