Safety Considerations for this Ins tr ument
WARNING This product is a Safety Class I instrument (provided with a protective
earthing ground incorporated in the power cord). The mains plug shall only
be ins erte d in a so ck et ou tlet pr ovid ed w ith a pro tec tive ear th cont act. An y
interruption of the protective conductor i nside or outside of the product is
likely to make the product dangerous. Intentional interruption is
prohibited..
Whenever it is likely that the protection has been impaired, the instrument
must be made inoperative and be secured against any unintended operation.
If this instrument is to be energized via an autotransformer (for voltage
reduction), make sure the common terminal is connected to the earth
termin a l o f the power source.
If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used in a normal
condition (in which all means for protection are intact) only.
No operator serviceable parts in this product. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.
Servicing instructions are for use by qualified personnel only. To avoid
electrical shock, do not perform any servicing unless you are qu alified to do
so.
The opening of covers or removal of parts is likely to expose dangerous
voltages. Disconnect the product from all voltage sources while it is being
opened.
Adjustments described in the manual are performed with power supplied to
the instrument while protective covers are removed. Energy available at
many points may, if contacted, result in personal injury.
The power cord is con nected to internal capacitors that my remain l iv e for
5 seconds after disconnecting the plug from its power supply.
For Continued protection against fire hazard, replace the line fuse(s) only
with 250 V fuse(s) or the same current rating and type (for example, normal
blow or time delay). Do not use repaired fuses or short circuited
fuseholders.

CAUTION: Always use the three-prong ac power cord supplied with this product. Failure to ensure
adequate earth grounding by not using this cord may cause product damage.
This product is designed for use in Installation Category II and Pollution Degree
2 per IEC 1010 and IEC 664 respectively. For indoor use only.
This product has autoranging line voltage input, be sure the supply voltage is
within the specified range.
Ventilation Requirements: When installing the product in a cabinet, the
convection into and out of the product must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum operating
temperature of the product by 4° C for every 100 watts dissipated in the cabinet.
