Instruction Manual Revision 3.11
1-1
1Safety
Read this chapter carefully before installation and use of the instrument.
1.1 Introduction
The instrument described in this manual has been designed for use by properly trained
personnel only.
Adjustment, maintenance and repair of the exposed equipment should only be carried out by
qualified personnel who are aware of hazards involved.
1.2 Safety Precautions
For the correct and safe use of the instrument, it is essential that both operating and servicing
personnel follow generally accepted safety procedures in addition to the safety precautions
specified in this manual. Specific warning and caution statements, where applicable, are found
throughout this manual. Note that warning and caution statements and/or symbols are marked
on the instrument as well.
This manual provides technical information important for safe operation of the equipment.
Please refer to the relevant sections of the manual for technical specifications, installation and
operating instructions.
Special attention must be paid to the following issues:
♦Protective earthing of the instrument is required for the accessible terminals to be safe.
(IEC 1010-1 Safety class I instrument)
♦The actual environmental conditions must be checked against the specification
♦Mains voltage must be inside the specified range
The opening of covers or removal of parts, except those to which access can be gained by
hand, is liable to expose live parts and terminals.
If adjustment, maintenance, or repair of the opened instrument is unavoidable, it must only be
carried out by a skilled person who is aware of the hazards involved.
1.3 Caution and Warning Statements
Caution
Used to indicate correct operation or maintenance in order to prevent damage to, or destruction
of equipment or other property.
Warning
Used to indicate a potential hazard that requires correct procedures or practices in order to
prevent personal injury.

1.4.2 Equipment Ratings
The instrument can be used with a mains voltage supply of:
Voltage range:
90 –132VAC / 180 -250 V AC
Frequency:
47 -63 Hz
The power consumption:
Does not exceed 50 VA
The instrument is designed for the following environmental conditions:
♦Indoor use
♦Altitudes up to 2000 m
♦Temperatures between 5oC and 40oC
Maximum relative humidity of 80% for temperatures up to 31oC, decreasing linearly to 50%
relative humidity at 40oC.
The instrument is equipped with a number of input and output terminals as described in the
Chapter Product Data.
The terminals are protected from becoming hazardous live by means of basic insulation and
protective screening.
Whenever it is likely that safe operation is impaired, the instrument must be made inoperative
and secured against unintended operation. The appropriate servicing authority must be
informed.
For example, safety is likely to be impaired if the instrument fails to perform the intended
measurements or shows visible damage.
WARNING: Protection provided by the equipment may be impaired, if the equipment is used in
a manner not specified by this manual.
ATTENTION
1.5 Electrostatic Sensitive Devices
All ICs and many other semi-conductors are susceptible to electrostatic discharges ESD).
Careless handling during repair can reduce lifetime drastically.
When repairing, make sure that you are connected to the same potential as the mass of the set
via a wrist wrap with resistance. Keep components and tools also at this potential.
