Device GND connection helps ensure device lightning protection and anti-interference. You should

connect the GND cable before powering on the Device, and power off the Device before

disconnecting the GND cable. There is a GND screw on the Device cover board for the GND cable,

which is called enclosure GND.

Step 1

Remove the GND screw at the enclosure GND with a cross screwdriver.

Step 2

Connect one end of the GND cable with the cold-pressed terminal, and fix it on the

enclosure GND with the GND screw.

Step 3

Connect the other end of the GND cable to the ground.

The sectional area of the GND cable needs to be more than 2.5 mm

resistance needs to be less than 4 Ω.

Redundant power input supports two-channel power, which are PWR2 and PWR1. You can select the

other power for continuous power supply when one channel of power breaks down, which greatly

improves the reliability of network operation.
