Guidelines for Powering
Nonisolated DC PanelView
Plus Terminals
To apply 24V DC power to a nonisolated PanelView Plus terminal, you must
follow specific guidelines in addition to regulatory requirements:
• Use the appropriate power supply.
• Use multiple power supplies for a system with multiple PanelView Plus
terminals.
• Use a single point ground.
• Wire the terminal block correctly.
• Apply the correct input voltage to the PanelView Plus terminal.
Use the Appropriate Power Supply
Each nonisolated PanelView Plus terminal in a system must be powered by its
own power supply with the correct electrical ratings. Use a UL Class 2 or an IEC
SELV power source to meet regulatory, electrical shock, and fire prevention
requirements.
The PanelView Plus 700 to 1500 terminals with an isolated DC logic module do
not require the use of a UL Class 2 power source for UL installations.
The supply you choose depends on the regulatory agency that is applicable to the
installation. The 2711P-RSACDIN power supply is approved for use with
PanelView Plus terminals in most installations.
Refer to
Connect PanelView Plus DC Terminals to DC Power on page 15 for an
explanation of the power source requirements.
WARNING: Disconnect all power before installing or replacing
components. Failure to disconnect power may result in electrical shock or
damage to the device.
