PanelView Plus and PanelView Plus Compact 400 and 600 Terminals
Publication 2711P-IN002G-EN-P - November 2009
DC Power Connections
PanelView Plus devices with an integrated, nonisolated, DC power supply have these power
ratings:
•
24V DC nom (18…30V DC)
•
25 W max (1.0 A at 24V DC)
The power supply is internally protected against reverse polarity of the DC+ and DC-
connections. Connecting DC+ or DC- source to the functional earth terminal may damage
the device.
The input power terminal block is removable and supports these wire sizes.
The non-isolated power supply does not provide galvanic isolation. A Class 2 Safety
Extra-Low Voltage (SELV) isolated power supply with a 24V DC nominal output voltage is
required to power the terminal.
External Power Supply
Use a single, 24V DC power supply to power each PanelView Plus terminal, such as catalog
number 2711P-RSACDIN. Using a separate, isolated, and ungrounded source to power each
terminal prevents ground loop currents from damaging the terminals.
The output on the power supply must be isolated from the input and not connected to earth
ground.

ATTENTION
Use a Class 2 or SELV 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 the conductors, and between conductors
and functional earth or protective earth does not exceed a safe value.
