Chapter 2 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 .
Table 17 - DC Power Ratings
Terminal Power Supply Input Voltage, nom Power Consumption, max
400, 600 Nonisolated 24V DC (18…30V DC) 15 W (0.6 A at 24V DC)
1000 Isolated 24V DC (18…32V DC) 70 W (2.9 A at 24V DC)
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.
Table 18 - Power Supply Criteria
If the PanelView Plus 6 Device Use a 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.
