Equipment Operation

Warnings and Cautions

This guide uses warnings and cautions to denote hazards.

WARNING A warning calls attention to a procedure, practice or the

like, which, if not correctly performed or adhered to, could

result in injury or the loss of life. Do not proceed beyond a

warning until the indicated conditions are fully

understood and met.

Caution A caution calls attention to a procedure, practice or the like which,

if not correctly performed or adhered to, could result in damage to

or the destruction of part or all of the equipment. Do not proceed

beyond a caution until the indicated conditions are fully

understood and met.

Personal Safety Considerations

WARNING This is a Safety Class I product (provided with a protective

earthing ground incorporated in the power cord). The

mains plug shall only be inserted in a socket outlet

provided with a protective earth contact. Any interruption

of the protective conductor, inside or outside the

instrument, is likely to make the instrument dangerous.

Intentional interruption is prohibited.

If this instrument is not used as speciﬁed, the protection

provided by the equipment could be impaired. This

instrument must be used in a normal condition (in which

all means of protection are intact) only.

No operator serviceable parts inside. Refer servicing to

qualiﬁed personnel. To prevent electrical shock, do not

remove covers.

For continued protection against ﬁre hazard, replace the

line fuse(s) only with fuses of the same type and rating (for

example, normal blow, time delay, etc.). The use of other

fuses or material is prohibited.

General Safety Considerations

WARNING Before this instrument is switched on, make sure it has

been properly grounded through the protective conductor

of the ac power cable to a socket outlet provided with

protective earth contact.

Any interruption of the protective (grounding) conductor,

inside or outside the instrument, or disconnection of the

protective earth terminal can result in personal injury.

Caution Any adjustments or service procedures that require operation of

the instrument with protective covers removed should be

performed only by trained service personnel.

Markings

The CE mark shows that the product complies with

all the relevant European legal Directives (if

accompanied by a year, it signiﬁes when the design

was proven.

This is the symbol of an Industrial Scientiﬁc and

Medical Group 1 Class A product.

The CSA mark is a registered trademark of the

Canadian Standards Association.

External Protective Earth Terminal.

While this is a Class I product, provided with a

protective earthing conductor in a power cord, an

external protective earthing terminal has also been

provided. This terminal is for use where the earthing

cannot be assured. At least an 18AWG earthing

conductor should be used in such an instance, to

ground the instrument to an assured earth terminal.
