Power Connections Chapter 3

External Power for 700 to 1500 Isolated DC Terminals

(2711P-RxxDx Logic Modules)

Use an SELV or PELV 24V DC power supply, such as cat. no.

2711P-RSACDIN, to power the isolated DC PanelView Plus terminal.

The isolated DC terminals may be powered by the same power source

as other equipment, by a DC power bus.

Earth/Ground Connection

PanelView Plus devices with a DC power input have an earth/ground

terminal that you must connect to a low-impedance earth/ground.

• The 700 to 1500 terminals have the earth/ground connection on

the rear of the display module.

• The 400 and 600 terminals have the functional earth/ground

connection on the power input terminal block.

The earth terminal requires a minimum wire gauge.

Earth Wire Specifications for DC Power

ATTENTION

Use an 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 and is required for

safety by Underwriters Laboratory.
