4.1 Connecting GND

Grounding the Device can protect it against lightning and interference.
Step 1 Remove the ground screw from the Device and 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 the needle-nose pliers.
Step 3 Connect the other end of the ground cable to the ground bar, then 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 securely grounded.
Step 1 Connect one end of the power cord to the power jack of the Device.
Step 2 Connect the other end of the power cord to the external power socket.

4.3 Connecting Ethernet Port

The Ethernet port is a standard RJ-45 port. With its 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, allowing you to use a cross-over cable or straight-through cable to connect the terminal
device to the network device.
