External Power Supply For Nonisolated DC Terminals
Use a single, 24V DC power supply, such as catalog number 2711P-RSACDIN, to
power each PanelView Plus device. 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
External Power for Isolated DC Terminals
Use an SELV or PELV 24V DC power supply, such as catalog number
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.
TIP
To identify nonisolated 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.
TIP
Isolated DC logic modules are identified by catalog number 2711P-RPxDx.
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.
