2.1.6 Earth Grounding
An earth ground hole (next to AC or DC power supply) is provided on the left side of the front panel with an earth ground
sign next to it. Grounding the device can help to release leakage of electricity to the earth safely so as to reduce injuries
from electromagnetic interference (EMI).
Prior to connecting to the power, it is important to connect the ground wire to the earth. Follow steps below to install
ground wire:
Step 1. Prepare one suitable ground screw and one grounding cable.
Step 2. Attach the grounding screw to the ring terminal of the grounding cable. Make sure that the grounding cable is
long enough to reach the earth.
Step 3. Use a screwdriver (or other tools) to fasten the grounding screw on the earth ground hole securely.
