Wiring and Safety Guidelines
Install the PanelView 550/600 touch screen terminal using publication 70E,
Electrical Safety Requirements for Employee Workplaces. In addition to the
NFPA general guidelines, follow these recommendations:
• Route incoming power to the PanelView 550/600 terminal by a separate path
from the communications cable.
• Where power and communication lines must cross, they should cross at right
angles. Communications lines can be installed in the same conduit as low
level DC I/O lines (less than 10 Volts).
• Grounding minimizes noise from Electromagnetic Interference (EMI) and is a
safety measure in electrical installations. To avoid EMI, shield and ground
cables appropriately.
• A source for grounding recommendations is the National Electrical Code
published by the National Fire Protection Association of Boston.
Enclosures
Mount the PanelView 550/600 touch screen terminal in a panel or enclosure to
protect the internal circuitry. The terminal meets NEMA Type 12/13 and 4X
(indoor use) ratings only when properly mounted in a panel or enclosure with the
equivalent rating.
Allow enough space within the enclosure for adequate ventilation. Consider heat
produced by other devices in the enclosure. The ambient temperature around the:
• PV550 terminal must be between 0 ° and 55 ° C (32 ° and 131 ° F).
• PV600 terminal must be between 0 ° and 50 ° C (32 ° and 122 ° F).
Make provisions for accessing the back panel of the terminal for wiring,
maintenance, installing a memory card, and troubleshooting.
