Safety Information - Fluke 5520A Service Manual

This Calibrator complies 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 manual contains information, warnings, and
cautions that must be followed to ensure safe operation and to maintain the Calibrator in
a safe condition. Use of this Calibrator in a manner not specified herein may impair the
protection provided by the Calibrator.
This Calibrator 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.

the manual.
AC POWER SOURCE
The Calibrator 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, use only the specified replacement fuse:
For 100 V or 120 V operation, use a 5A/250V time delay fuse (Fluke PN 109215).
For 220 V or 240 V operation, use a 2.5A/250V time delay fuse (Fluke PN 851931).
GROUNDING THE CALIBRATOR
The Calibrator uses controlled overvoltage techniques that require the Calibrator 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 CHASSIS GROUND binding post.
