Functional Earth Connection
PanelView Plus devices with a DC power input have a functional earth terminal that you must
connect to a low-impedance earth ground. The functional earth connection is on the power
input terminal block.
The functional earth terminal wiring requires a minimum wire gauge.
On most PanelView Plus devices, the functional earth terminal is internally connected to the
DC- terminal within the product.
The PanelView Plus devices have isolated and nonisolated communication ports.

IMPORTANT
The functional earth connection to ground is mandatory. This connection is required for
noise immunity, reliability, and Electromagnetic Compliance (EMC) with the European
Union (EU) EMC directive for CE-mark conformance.

ATTENTION
Damage or malfunction can occur when a voltage potential exists between two separate
ground points. Make sure the terminal does not serve as a conductive path between
ground points at different potentials.
