SAFETY TERMS IN THIS MANUAL
This instrument has been designed and tested in accordance with IEC publication
1010-1 (1992-1), Safety Requirements for Electrical Measuring, Control and Laboratory
Equipment, and ANSI/ISA-S82.01-1994, and CAN/CSA-C22.2 No. 1010.1-92. This User
Manual contains information, warning, and cautions that must be followed to ensure safe
operation and to maintain the instrument in a safe condition. Use of this equipment in a
manner not specified herein may impair the protection provided by the equipment.
This instrument is designed for IEC 1010-1 Installation Category II use. It is not designed
for connection to circuits rated over 4800 VA.
WARNING statements identify conditions or practices that could result in personal injury
or loss of life.
CAUTION statements identify conditions or practices that could result in damage to
equipment.
SYMBOLS MARKED ON EQUIPMENT
WARNING
Risk of electric shock. Refer to the manual (see the Index for
references).
GROUND Ground terminal to chassis (earth).
Attention Refer to the manual (see the Index for references). This
symbol indicates that information about usage of a feature is contained in
the manual.
AC POWER SOURCE
The instrument is intended to operate from an ac power source that will not apply more
than 264V ac rms between the supply conductors or between either supply conductor
and ground. A protective ground connection by way of the grounding conductor in the
power cord is required for safe operation.
USE THE PROPER FUSE
To avoid fire hazard, for fuse replacement use only the specified unit: 100 or 120 V
operation, 2 ampere/250 volt time delay; 200 or 240 V operation, 1 ampere/250 volt time
delay.
GROUNDING THE INSTRUMENT
The instrument utilizes controlled overvoltage techniques that require the instrument to
be grounded whenever normal mode or common mode ac voltages or transient voltages
may occur. The enclosure must be grounded through the grounding conductor of the
power cord, or through the rear panel ground binding post.
