4.1 Connecting GND
Normal GND connection of the device is the important guarantee for device lightning protection
and anti-interference. The steps for connecting the GND are as follows:
Step 1
Remove the ground screw on the device and place it properly. Pass the ground screw
through the round hole of the OT terminal of the ground cable. Turn the ground screw
clockwise with a cross screwdriver to fasten the OT terminal of the ground cable.
Step 2
Wind the other end of the ground cable into a circle with needle-nose pliers.
Step 3
Connect the other end of the ground cable to the ground bar, turn the hex nut clockwise
with a wrench to fasten the other end of the ground cable to the ground terminal.

4.2 Connecting Power Cord
Before connecting the power cord, make sure that the device is reliably grounded.
Step 1
Connect one end of the power cord into the power jack of the device accurately.
Step 2
Connect the other end of the power cord to the external power socket.
4.3 Connecting Ethernet Port
Ethernet port adopts standard RJ-45 port. With self-adaptation function, it can be automatically
configured to full duplex/half-duplex operation mode. It supports MDI/MDI-X self-recognition of the
cable, therefore, you can use cross-over cable or straight-through cable to connect terminal device
to network device.
