Installing An Ethernet Port Arrester - Ruijie RG-S6510-4C Hardware Installation And Reference Manual

Hardware Installation and Reference Guide
Figure 7-7 Power Arrester
Note
The power arrester does not come with the equipment. Please purchase it based on actual requirements.
Important points:

Make sure that the PE terminal of the power arrester is well grounded.

After the AC power plug of the switch is connected to the socket of the power arrester (surge protector power
strip), the surge protection function is implemented only if the LED indicating operation status is green and
the LED indicating alarm status is OFF.

If the LED on the power arrester turns red, check whether it is caused by poor grounding connection or by
the reversed connection of the null and live lines. The detection method is as follows: Use a multimeter to
measure the polarity of the power socket for the arrester when the LED turns red. If the null line is on the left
and the live line is on the right (facing the socket), the arrester's PE terminal is not grounded. If not, the null
and live lines are reversed. In this case, you should open the power arrester and reverse the null and live
lines. If the LED is still red, the arrester's PE terminal is not grounded.
