DC Power Connections
DC-powered PanelView Plus 6 devices have an integrated, isolated 24V DC
power supply with these power ratings:
•
24V DC nominal (18…32V DC)
•
70 W maximum (2.9 A at 24V DC)
The power supply is internally protected against reverse polarity of the DC+ and
DC- connections. Connecting DC+ or DC- to the earth/ground terminal may
damage the device.
The input power terminal block supports these wire sizes.
External Power Supply
Use a SELV or PELV 24V DC power supply, such as catalog number 2711P-
RSACDIN, to power PanelView Plus 6 terminals with a DC power input.
The terminals may be powered by the same power source as other equipment, by
a DC power bus.
Earth/Ground Connection
PanelView Plus 6 devices with a DC power input have an earth/ground terminal
that you must connect to a low-impedance earth/ground. The earth/ground
connection is on the rear of the display module.

ATTENTION:
Use a SELV or PELV supply as required by local wiring codes
for your installation. The SELV and PELV power sources provide protection
so that under normal and single fault conditions, the voltage between
conductors and earth ground does not exceed a safe value.
IMPORTANT
The earth/ground 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. This connection is required for safety by Underwriters
Laboratory.
