PanelView 800 HMI Terminals 15
Publication 2711R-IN001A-EN-P - January 2015
Choose a Power Supply
Use a dedicated 24V DC, Class 2 Safety Extra-low Voltage (SELV) or Protective Extra-low Voltage (PELV)
power supply to power each PanelView Terminal.
PanelView 800 devices have been tested to operate with 1606-XLP power supplies. To use another power
supply, review the criteria in the table.
WARNING: If you connect or disconnect the USB cable with power applied to this module or any
device on the USB network, an electrical arc can occur. This could cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
ATTENTION: Use a Class 2, Safety Extra-low Voltage (SELV), or Protective Extra-low Voltage
(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 the
conductors, and between conductors and functional earth, does not exceed a safe value.
WARNING: When you insert or remove connection(s) while power is on, an electrical arc can
occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding. Repeated
electrical arcing causes excessive wear to contacts on both the module and its mating connector.
Worn contacts may create electrical resistance that can affect module operation.
WARNING: Do not connect directly to line voltage. Line voltage must be supplied by a suitable,
approved isolating transformer or power supply having short circuit capacity not exceeding
100 VA maximum or equivalent.
Power Supply Criteria
If the PanelView 800 terminal 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 800 device
provided that no ground loops are
created. A PELV power 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 devices.
