Earth/Ground Connection
PanelView Plus 6 compact terminals use a DC power input and have an earth/
ground terminal that you must connect to a low-impedance earth/ground:
• On 400 and 600 terminals, the earth/ground connection is on the power
terminal block.
• On 1000 terminals, the earth/ground connection is on the rear of the
display module.
IMPORTANT The earth/ground connection to ground is mandatory. This connection is
required for the following:
• Noise immunity, reliability, and Electromagnetic Compliance (EMC) with
the European Union (EU) EMC directive for CE-mark conformance
• Safety by Underwriters Laboratory

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.
