standards: UL, NEC 2002, NEBS Level 3, IEC, and CE.
ADMONISHMENTS
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what
may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of
the triangular alert icon (seen below), and are listed in descending order of severity of injury or
damage and likelihood of occurrence.
