Product-Related Safety Precautions
The product has been tested for safety and approved as shipped from the
factory. The following safety precautions are not related to any specific
procedures and therefore do not appear elsewhere in this manual. They
are recommended precautions that personnel must understand and
apply during different phases of operation and maintenance.
WARNING Keep away from live circuits. Operating personnel must observe safety
regulations at all times. Component replacement or internal
adjustments must be made by qualified maintenance personnel. Do not
replace components with the power cable connected. Under certain
conditions, dangerous voltages may exist for some time even with the
power cable disconnected. To avoid injuries, disconnect power and
discharge circuits before touching them.
WARNING Do not service alone. Under no circumstances should any person reach
into parts and assemblies that are mains powered and alive, for the
purpose of servicing, except in the presence of someone who is
capable of rendering aid.
WARNING Personnel working with or near high voltages should be familiar with
modern methods of resuscitation.
WARNING Do not service a live system outdoors. Do not open units outdoors
when the enclosure used contains line voltage levels.
WARNING Do not operate in an explosive atmosphere, for example, when
flammable gases or fumes are present. Operation of any electrical
instrument in such an environment constitutes a definite safety hazard.
WARNING Do not substitute parts or modify the instrument. Because of the
danger of introducing additional hazards, do not install unsuitable
parts in the instrument. Contact Vaisala or its authorized representative
for repairs to ensure that safety features are maintained.
