(EMI). Run the ground connection from the ground screw to the grounding surface prior to

connecting devices.

ATTENTION

This product is intended to be mounted to a well-grounded mounting surface such as a metal

panel.

STEP 3: Insert the plastic terminal block

connector prongs into the terminal block

receptor, which is located on the VPort
