What is in this Guide?
The
5520A Operator Guide
is a condensation of
information in the
5520A Operators Manual
(PN
688739). For complete descriptions of the
Calibrator’s features, functions, and operating
procedures, refer to the
Operators Manual
.
Safety Information
Warning
The Calibrator can supply lethal voltages.
Read this guide before operating the
Calibrator.
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.

Safety Information (cont)
Symbols
Warning. Risk of electric shock. Refer
to the manual for information.
Chassis (earth) ground terminal.
Attention. Refer to the manual for
information about this feature. This
symbol appears on the rear panel
CHASSIS GROUND terminal and by
the fuse compartment.
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 5 A/250 V
time delay fuse (Fluke PN 109215).
•For 200 V or 240 V operation, use a 2.5 A/250
V time delay fuse (Fluke PN 851931).
5
Safety Information (cont)
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.
Use the Proper Power Cord
Use only the power cord and connector
appropriate for the voltage and plug configuration
in your country.
Use only a power cord that is in good condition.
Refer power cord and connector changes to
qualified service personnel.
Do Not Operate in Explosive
Atmospheres
To avoid explosion, do not operate the
Calibrator in an atmosphere of explosive gas.
Check Insulation Ratings
Verify that the voltage applied to the unit under
test does not exceed the insulation rating of the
UUT and the interconnecting cables.

Safety Information (cont)
Do Not Remove Cover During Operation
To avoid personal injury or death, do not
remove the Calibrator cover without first
removing the power source connected to the
rear panel. Do not operate the Calibrator
without the cover properly installed. Normal
calibration is accomplished with the cover
closed. Access procedures and the warnings for
such procedures are contained in the
5520A
Service Manual
. Service procedures are for
qualified service personnel only.
Do Not Attempt to Operate if Protection
May Be Impaired
If the Calibrator appears damaged or operates
abnormally, protection may be impaired. Do not
attempt to operate the Calibrator under these
conditions. Refer all questions of proper
Calibrator operation to qualified service
personnel.

Unpacking and Inspecting
The Calibrator is shipped in a container designed
to prevent damage. Inspect the Calibrator carefully
for damage and immediately report any damage to
the shipper. Instructions are included in the
shipping container.
When you unpack the Calibrator, determine if your
order is complete. Standard equipment is listed in
the next table. Report any shortage to the place of
purchase or to the nearest Fluke Technical Service
Center.
If reshipping the Calibrator, use the original
container. If it is not available, you can order a
new container from Fluke by indicating the
Calibrator’s model and serial number.

Replacing the Fuse
Caution
To avoid damage to the Calibrator,
verify that the correct fuse is installed
for the selected line voltage. For 100 V
and 120 V, use 5 A/250 V time delay; for
200 V and 240 V, use 2.5 A/250 V time
delay.
Disconnect line power. To replace the fuse, refer
to the following figure.
