1 About this manual
Throughout this operating manual the Power Quality Analyzer PQA will be referred to
simply as the PQA.
The most recent update of this manual can always be found on our website www.frako.com.
1.1 Objective
This operating manual has been prepared for persons who install, connect, commis-
sion and operate the PQA. The manual must be read through carefully and completely
before any work on or with the instrument is carried out. All actions taken must be in
accordance with this manual.
1.2 Safekeeping
This operating manual contains important instructions for operating the PQA safely,
correctly and cost-effectively. It is to be considered part of the instrument itself and
must be held in a secure place where it can be referred to at all times.
1.3 Symbols used in this manual
Special instructions in this operating manual are marked by symbols and separated
from the other text by horizontal lines.
Warning signs
In order to avoid accidents, death or injury and damage to assets, these instructions
must always be followed. The warning signs consist of the appropriate signal word
– DANGER, WARNING, CAUTION or ATTENTION – plus a yellow symbol on the left-
hand side, as shown below:
WARNING!
Type of danger!
Description of the danger and possible consequences
–Measures to avoid the danger

FRAKO | Operating Manual | Power Quality Analyzer 1101 – PQA
The symbols and signal words classify the severity of the danger:
Symbol Signal word Meaning
DANGER This signal word indicates a hazard with a high level of risk that if
not avoided can result in death or serious injury.
WARNING This signal word indicates a hazard with an intermediate level of
risk that if not avoided can result in death or serious injury.
CAUTION This signal word indicates a hazard with a low level of risk that if
not avoided can result in slight or moderate injury.
ATTENTION Damage to equipment could occur if this sign is not heeded.
Notes
Notes supplement the general text with additional information on the correct func-
tioning and fault-free operation of the PQA. They are marked with the white-on-blue
symbol on the left-hand side, as shown below:

2 Safety
2.1 Intended use
Within the scope of the technical data (see Section 3, Technical data), the Power
Quality Analyzer PQA is intended for the measurement and analysis of the secondary
electrical distribution system supplying the user. Any use of the instrument that devia-
tes from its intended use must be expressly approved by the manufacturer.
2.2 Instrument-specific dangers
The PQA has been manufactured using state-of-the-art technology. Nevertheless, not
all potential dangers can be excluded.
Failure to observe the safety instructions can result in death, serious injury or severe
damage to equipment and other assets.
Danger from electricity
The PQA operates at the supply voltage. Touching live components at the instrument
terminals and connecting cables can cause serious injury or may even be life-threat-
ening.
– Installation, commissioning and decommissioning of the PQA may only be carried
out by appropriately qualified technicians who are also familiar with and under-
stand the contents of this manual.
– When the PQA is being installed or serviced, the instrument and the electrical
system must be isolated from the power supply.
– The isolated electrical system must be locked out and tagged out to prevent its
being inadvertently switched on again.
– It must be verified that none of the terminals are live.
– All live components in the vicinity must be covered to prevent inadvertent contact.
– Current transformer circuits must be short-circuited before they are interrupted.
– Only approved installation cables must be used.
– The PQA must only be employed on duties up to the specified maximum power.
Overloading the instrument can result in its destruction, create a fire hazard or
cause an electrical accident. The load ratings for the various connections must
not be exceeded.
– Do not open the PQA.
– When the PQA is in operation, the USB port must not be touched.

Safety | 7
FRAKO | Operating Manual | Power Quality Analyzer 1101 – PQA
Danger from heat
The instrument terminals can become hot during operation.
– After the PQA has been operating, sufficient time must be allowed for the PQA
and its terminals to cool down before work is carried out on the connections.
2.3 Management information
Personnel qualifications
The following qualifications are required for personnel working with the PQA:
– Installing, commissioning, troubleshooting (installation):
electricians
– Operation, troubleshooting (faulty configuration):
persons who have read and understood the operating manual.
– Troubleshooting (instrument faults):
FRAKO Service + Support
User responsibility
In commercial operations in Germany, it is essential to comply with the regulations
of the Social Accident Insurance Institution covering electrical installations. In other
countries, the equivalent local regulations must be followed.
The safety of the system in which the PQA is incorporated is the responsibility of the
persons installing and operating the system.
For safety reasons and to retain conformity with product approval requirements
(CE marking), the user is not permitted to convert or otherwise modify the PQA.
The user must ensure that all operators are familiarized with this operating manual
and follow it at all times.
2.4 Disclaimer
No claims under guarantee shall be valid in the event of damages caused by failure
to observe the instructions in this operating manual. We shall not be held liable for
consequential damages!
Incorrect operation or failure to observe the safety instructions will invalidate all claims
under the guarantee, and no liability is accepted for any injuries to persons or dam-
ages to assets arising therefrom or occasioned thereby!

8 | Safety
Power Quality Analyzer 1101 – PQA | Operating Manual | FRAKO
2.5 Relevant standards
Installation and commissioning of the instrument in industrial plant must be carried out
in strict compliance with the following standards:
– EN 61508-1:2011-02; VDE 0803-1:2011-02
For this product all other currently valid laws, standards, regulations and safety rules
(IEC, EN, VDE, etc.) relating to the protection of persons and property must be strictly
