3.4 Use Lightning Arrester
Power lightning arrester and signal lightning arrester are used for lighting protection.
Power lightning arrester is used for limiting the voltage surge due to a lightning. If an
outdoor AC power cord should be directly connected to the device, please use a power
lightning arrester.
Note: Power lightning arrester is not provided with our product. If needed, please self
purchase it.
Signal lightning arrester is used to protect RJ45 ports of the device from lightning.
When cabling outdoors, please install a signal lightning arrester before connecting the
cable to the device.
When purchasing or using a signal lightning arrester, please observe the following
rules:
■
The port rate of the signal lightning arrester should match the rate of the desired port
