PanelView Plus 700 to 1500 and PanelView Plus Compact 1000 Terminals and Display Modules 17
Publication 2711P-IN001I-EN-P - November 2009
External Power Supply For Non-isolated DC Terminals
Use a single, 24V DC power supply to power each PanelView Plus device, 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.
Multiple AC Power Supplies to Power Multiple DC Terminals
TIP
To identify non-isolated DC logic modules refer to the PanelView Plus Terminals user
manual, publication 2711P-UM001
.
ATTENTION
Use a Class 2 or SELV supply as required by local wiring codes for your installation. The
Class 2 and SELV power sources provide protection so that under normal and single-fault
conditions, the voltage between the conductors, and between the conductors and
functional earth or protective earth does not exceed a safe value.
