Notes are helpful hints and information that is supplemental to the main text.
CAUTION:
A Caution statement indicates situations where there may be undefined or
unwanted consequences of an action, potential for data loss or an equipment
problem.
WARNING:
A Warning statement indicates situations where damage may occur, people
may be harmed, or there are serious or dangerous consequences of an action.
WARNING:
RISK OF ELECTRIC SHOCK! This warning statement indicates situations where
there is a risk of electric shock.
WARNING:
RISK OF ELECTRIC SHOCK! Enclosures without an accessible power disconnect
device cannot be serviced safely. Before removing dimmer or control modules
for service, de-energize main feed to dimmer enclosure and follow
appropriate Lockout/Tagout procedures as described in NFPA Standard 70E.
It is important to note that electrical equipment such as enclosures can
present an arc flash safety hazard if improperly serviced. This is due to
available large short circuit currents on the feeders of the equipment. Any
work on energized equipment must comply with OSHA Electrical Safe
Working Practices.
