Earth Ground Connection
An earth ground connector is provided on the left side panel.
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 appropriate 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.
