1 Preface
Congratulations for purchasing and using METREL A 1560 Burn Link Adapter
accessory with METREL test and measuring instruments. The A 1560 is extension of
a.c. voltage withstanding voltage testers with burn test function intended for searching
weak locations that failed during withstanding voltage test.
A 1560 Burn Link Adapter is special accessory intended for using only with METREL
withstanding voltage testers like MI 3394.

2 Safety and operational considerations
2.1 Warnings and note
In order to reach high level of operator’s safety during application of the A 1560 Burn
Link adapter as well as to keep the test accessory and equipment undamaged, it is
necessary to consider the following general warnings:
Read this user manual carefully, otherwise use of the A 1560 may be
dangerous for the operator, for test equipment or for the tested object!
If the A 1560 is used in a manner not specified in this user manual or the
manual of target test equipment, the protection provided by the A 1560 and
equipment may be impaired!
Consider all generally known precautions in order to avoid risk of electric
shock while dealing with hazardous voltages!
The A 1560 is intended for connection to secondary voltages based on
300 V CAT II overvoltage category of supply voltage of master instrument!
Never use the A 1560 with voltages higher than rated!
Service intervention is allowed to be carried out only by a competent
authorized person!
Do not use the A 1560 if any damage is noticed!
Only adequately trained and competent persons may operate the
equipment.
Eyes protection glasses required: open electric arch could emit high
energy spectrum above visible!
Liberated gases: electric arch on insulation material will generate
unpredictable liberated gasses, test area shall be proper vented and/or
liberated gases exhausted.
A 1560 is intended for intermittent operation, any overloading would lead
to impaired safety!
Note:
The A 1560 Burn Test Adapter is passive type device, there is no active
component inside.

Symbol
Description
Read the Instruction manual with special care to safety
operation«.
The symbol requires an action!
The symbol on the adapter means “Hazardous voltage may be
present at the test terminals!”.
Product is protected by Double/Reinforced insulation.
Mark on your equipment certifies that it meets European Union
requirements for EMC, LVD, and ROHS regulations.
This equipment should be recycled as electronic waste.
2.3 Standards applied
The A 1560 Burn Link Adapter is manufactured and tested according to the following
standards, listed below.
Safety (LVD)
EN 61010 - 1
Safety requirements for electrical equipment for measurement,
control, and laboratory use –Part 1: General requirements
EN 61010 - 2 - 030
Safety requirements for electrical equipment for measurement,
control and laboratory use –Part 2-030: Particular requirements
for testing and measuring circuits
EN 61010 - 031
Safety requirements for electrical equipment for measurement,
control and laboratory use –Part 031: Safety requirements for
hand-held probe assemblies for electrical measurement and test
Note about EN and IEC standards:
Text of this manual contains references to European standards. All standards of EN
6xxxx (e.g. EN 61010) series are equivalent to IEC standards with the same number
(e.g. IEC 61010) and differ only in amended parts required by European harmonization
procedure.

4 A 1560 operation
-Connect the A 1560 Burn Link Adapter plug connector (1) to the master
instrument HV output.
-Connect HV test probe to A 1560 Burn Link Adapter socket connector (3).
-On the master instrument select withstanding voltage test function.
-Set the following test parameters:
-Withstanding voltage test level: as required by requested withstanding test
procedure,
-Trip-out current limit: 100 mA,
-Test duration: see technical specifications.
-2-hand operation of test probes must be applied or proper safe test
connection prior start of withstanding voltage test!
-Keep proper safety distance to tested object!
-Start the withstanding voltage test on the master instrument.
-Attach HV test probes to observed insulation (if hand operated).
-Stop withstanding voltage test immediately after the breakdown location is
observed (visible electrical arch) and remind the breakdown location.
Warnings:
Eyes protection glasses required: open electric arch could emit high-
energy spectrum above visible!
Liberated gases: electric arch on insulation material will generate
unpredictable liberated gases, test area shall be proper vented and/or
liberated gases exhausted.
A 1560 is intended for intermittent operation, any overloading would lead
to impaired safety!
