PanelView 800 HMI Terminals Installation Instructions
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 800 terminal.
PanelView 800 terminals have been tested to operate with 1606-XLP power supplies. To use another power
supply, review the criteria in the table.
Remove the Power Terminal Block
PanelView 800 terminals ship with a power terminal block installed. You can remove the power terminal block
for ease of installation, wiring, and maintenance.
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.
WARN ING: When you insert or remove connections 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.
WARN ING: 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
100VA 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 terminal
if 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 helps prevent ground loops from
damaging the devices.
ATTENTION: Disconnect all power before installing or replacing components. Failure to
disconnect power may result in electrical shock or damage to the terminal.
WARN ING: When you connect or disconnect the Removable Power Terminal Block (RTB) while
the module is powered, 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.
