GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cover must be connected to
an electrical protective earth ground. The instrument must be connected to the ac
power mains through a grounded power cable, with the ground wire firmly
connected to an electrical ground (safety ground) at the power outlet. Any
interruption of the protective (grounding) conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that could result in
personal injury.
FUSES
Only fuses with the required rated current, voltage, and specified type (normal
blow, time delay, etc.) should be used. Do not use repaired fuses or short-circuited
fuse holders. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
DO NOT REMOVE THE INSTRUMENT COVER
Operating personnel must not remove instrument covers. Component replacement
and internal adjustments must be made only by qualified service personnel.
Instruments that appear damaged or defective should be made inoperative and
secured against unintended operation until they can be repaired by qualified
service personnel.
