In addition to the warnings previously listed, additional cautions are
posted throughout the manual. These warnings may be designated by an
appropriate symbol inside an equilateral triangle. General cautions are
indicated with an exclamation point (see diagram, left). Read and follow
these important instructions. Failure to observe these instructions can
result in permanent damage to the unit, significant property damage, and
personal injury.
Hot surface cautions (see diagram, left) may be attached on or near hot
surfaces of the CMRV-4500. Avoid touching these surfaces when running
profiles at temperatures above 50°C.
The Protective Conductor Terminal symbol is used to indicate required
ground connections for your instrument electrical supply.
WARNING When supplying power to this instrument, connect the protective ground
(earth) terminals of the instrument to the protective conductor of the
(supplied) line (MAINS) power cord. The main plug for the power cord
should only be inserted in a socket outlet (receptacle) provided with a
protective ground (earth) contact. Do not use an extension cord (power
cable) without a protective conductor (grounding).
The ~MAINS symbol indicates instructions or connections for the AC
power supply. The AC Power input must match the electrical specifica-
tions listed on the label on the rear panel of the instrument. The supplied
AC Mains power cord must be attached to the connector labelled
~MAINS. This connection serves as a means of disconnect and should be
readily accessible.
