Statement 1029
—Blank Faceplates and Cover Panels
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages
and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all
cards, faceplates, front covers, and rear covers are in place
Warning
Site Planning
This section contains site-planning information, and will help you plan for the installation of the controller.
General Precautions
Observe the following general precautions when using and working with the controller:
• Keep your system components away from radiators and heat sources and do not block cooling vents.
• Do not spill food or liquids on your system components and never operate the product in a wet
environment.
• Do not push any objects into the openings of your system components. Doing so can cause fire or electric
shock by shorting out interior components.
• Position system cables and power supply cable carefully. Route system cables and power supply cable
and plug such that they cannot be stepped on or tripped over. Be sure that nothing else rests on your
system component cables or power cable.
• Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local and national wiring rules.
• If you turn off your system, wait at least 30 seconds before turning it on again to avoid system component
damage.
