this product or any products connected to it.

To avoid potential hazards, use this product only as specified.

Only qualified personnel should perform service procedures.

While using this product, you may need to access other parts of the system. Read
the General Safety Summary in other system manuals for warnings and cautions
related to operating the system.

ToAvoidFireor

Personal Injury

Use Proper Power Cord. Use only the power cord specified for this product and
certified for the country of use.

Connect and Disconnect Properly. Do not connect or disconnect probes or test
leads while they are connected to a voltage source.

Ground the Product. This product is grounded through the grounding conductor
of the power cord. To avoid electric shock, the grounding conductor must be
connected to earth ground. Before making connections to the input or output
terminals of the product, ensure that the product is properly grounded.

Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings
and markings on the product. Consult the product manual for further ratings
information before making connections to the product.

Do not apply a potential to any terminal, including the common terminal, that
exceeds the maximum rating of that terminal.

Powering Off. The power cord provides Mains disconnect.

Replace Batteries Properly. Replace batteries only with the same type and rating.

Do Not Operate Without Covers. Do not operate this product with covers or panels

removed.

Use Proper Fuse. Use only the fuse type and rating specified for this product.

Avoid Exposed Circuitry. Do not touch exposed connections and components

when power is present.

Wear Eye Protection. Wear eye protection if exposure to high-intensity rays or
laser radiation exists.

Do Not Operate With Suspected Failures. If you suspect there is damage to this
product, have it inspected by qualified service personnel.

Do Not Operate in Wet/Damp Conditions.

Pollution Degree Descriptions A measure of the contaminat es that could occur in the environment around and within a product.

Typically the internal environment inside a product is considered to be the same as the external.
Products should be used only in the environment for which they are rated.

Pollution Degree 1 No pollution or only dry, nonconductive pollution occurs. Products in

this category are generally encapsulated, hermetically sealed, or
located in clean rooms.

Pollution Degree 2 Normally only dry, nonconductive pollution occurs. Occasionally a

temporary conductivity that is caused by condensation must be
expected. This location is a typical office/home environment.
Temporary condensation occurs only when the product is out of
service.

Pollution Degree 3 Conductive pollution, or dry, nonconductive pollution that becomes

conductive due to condensation. These are sheltered locations
where neither temperature nor humidity is controlled. The area is
protected from direct sunshi ne, rain, or direct wind.
