PanelView 550 Terminals 5
Publication 2711-IN009E-EN-P - February 2009
Wiring and Safety Guidelines
Install the PanelView 550 terminal using publication 70E, Electrical Safety
Requirements for Employee Workplaces. In addition to the NFPA general
guidelines, follow these recommendations:
•
Connect the PanelView terminal to its own branch circuit.
•
The input power source should be protected by a fuse or circuit breaker
rated at no more than 15 amps.
•
Route incoming power to the PanelView 550 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 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
terminal must be between 0…55
°
C (32…131
°
F).
Make provisions for accessing the back panel of the terminal for wiring,
maintenance, installing a memory card, and troubleshooting.
Required Tools
Other than the tools required to make the panel cutout, the tools required for
installation are:
•
7mm (M4) deep well socket wrench or nut driver.
•
small slotted screwdriver.
•
torque wrench (N•m, lb•in).
