Figure C-1 Schematic Diagram for the Power Arrester
The power arrester is not provided and customers have to purchase it.
Precautions for installation:

Ensure that the PE terminal of the power arrester is properly grounded.

After connecting the switch AC power plug to the socket of the power arrester (surge protection cable row),
surge protection function implements if the RUN LED is Green and the ALARM LED is OFF.

If the alarm LED on the power arrester is red, check whether there is the poor grounding connection or
reversed connection of null and live lines. You can use the multimeter to check the polarity of the power
socket for the arrester when the LED is red. If the N line is on the left and the L line is on the right, the
arrester PE terminal is not grounded. If the L line is on the left and the N line is on the right, the polarity of the
arrester power cable is reversed. If the LED is still red, the arrester PE terminal is not grounded.
Installing the Ethernet Port Arrester
During the switch usage, the Ethernet port arrester must be connected to the switch to prevent the switch damage
by lightning before the outdoor network cable connects to the switch.
Tools: cross or straight screwdriver, multimeter, and diagonal pliers
Installation steps:
1. Tear one side of the protection paper for the double-sided adhesive tape and paste the tape to the framework of the
Ethernet port arrester. Tear the other side of the protection paper for the double-sided adhesive tape and paste the
Ethernet port arrester to the switch framework. The paste location for the Ethernet port arrester must be as close to
the grounding terminal of the switch.
2. Based on the distance of the switch grounding terminal, cut the grounding line for the Ethernet port arrester and firmly
tighten the grounding line to the grounding terminal of the switch.
3. Use the multimeter to check whether the grounding line for the arrester is in good contact with the switch grounding
terminal and the framework.
