Figure 4-77 Install a power lightning arrester
Note that:
1) Make sure that the protection wire (PE) terminal of the power lightning arrester is well grounded Make sure that the protection wire (PE) terminal of the power lightning arrester is well grounded 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 router is plugged into the multi After the AC power cord of the router 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. 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 Pay attention and clear the alarm if the red LED is ON. You should correctly tell whether the Pay attention and clear the alarm if the red LED is ON. You should correctly tell whether the
grounding cable is not well connecte 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 the red LED is ON, use a multimeter to examine the polarity at the multi
power lightning arrester.
If the live and zero wires are on the left and right respectively (supposing that you are facing the If the live and zero wires are on the left and right respectively

you should open the power socket to correct the polarity. After that, if the red LED is still ON, you should open the power socket to correct the polarity. After that, if the red LED is still ON, 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. you can make sure that the PE terminal of the power lightning arrester is not grounded. you can make sure that the PE terminal of the power lightning arrester is not grounded.

against surge over-voltage resulting from lightning strokes and other interferences, and
minimize impact on the router. minimize impact on the router.
Because the signal lightning arrester is Because the signal lightning arrester is serially connected to a signal cable, the signal lightning
arrester must satisfy the requirements of network performance indexes such as data arrester must satisfy the requirements of network performance indexes such as data arrester must satisfy the requirements of network performance indexes such as data
transmission bandwidth, as well as the lightning protection performance requirement. Therefore, transmission bandwidth, as well as the lightning protection performance requirement. Therefore, transmission bandwidth, as well as the lightning protection performance requirement. Therefore,
before installing a signal lightning arrester, you need to consider such performance indexes of a signal lightning arrester, you need to consider such performance indexes of a signal lightning arrester, you need to consider such performance indexes of
the lightning arrester as lightning protection, bandwidth, transmission loss, and interface type. the lightning arrester as lightning protection, bandwidth, transmission loss, and interface type. the lightning arrester as lightning protection, bandwidth, transmission loss, and interface type.
