Install the Terminal

DC Power Connections

Terminals with an integrated 24V DC power supply have these power ratings.

The power supply is internally protected against reverse polarity. Connecting
DC+ or DC- to the earth/ground terminal can damage the device.

External Power Supply

Use a dedicated 24V DC, safety extra-low voltage (SELV) or protective
extra-low voltage (PELV) power supply to power each PanelView Plus 6
Compact device.

PanelView Plus 6 Compact terminals were tested to operate with the catalog
number 2711P-RSACDIN power supply. To use another power supply, review
the criteria in

Table 18

ATTENTION: Do not connect an AC power source to the terminal. Applying an
AC power source to the terminal can damage the device.

ATTENTION: Use a Class 2 SELV or PELV power supply as required by local wiring
codes for your installation. These power supplies provide protection so that
under normal and single fault conditions, the voltage between conductors and
earth ground does not exceed a safe value.

Description

Connects to equipment with isolated
communication ports

SELV or PELV power supply

Other equipment can share this power
supply with the PanelView Plus 6 device
provided that no ground loops are created.
A PELV source internally connects the
negative power terminal to chassis ground.

Does not connect to other equipment

Connects to equipment with
nonisolated communication ports

Dedicated, isolated, and
ungrounded SELV source to
power each terminal

This prevents ground loops from damaging
the device.

IMPORTANT

All ports on the terminals are electrically isolated, except for the USB ports.
