1.5 Hazards
Electric Shocks
DANGER!
Ignoring the following may result in injury:
•This equipment can endanger life by exposure to rotating machinery
and high voltages.
•The equipment must be permanently earthed due to the high earth
leakage current, and the inverter motor must be connected to an
appropriate safety earth.
•Ensure all incoming supplies are isolated before working on the
equipment. Be aware that there may be more than one supply
connection to the inverter.
•There may still be dangerous voltages present at power terminals
(motor output, supply input phases, DC bus and the brake, where
fitted) when the motor is at standstill or is stopped.
•For measurements use only a meter to IEC 61010 (CAT III or higher).
Always begin using the highest range.
CAT I and CAT II meters must not be used on this product.
•Allow at least 10 minutes for the inverter's capacitors to discharge to
safe voltage levels (<50 V). Use the specified meter capable of
measuring up to 1000 V DC & AC rms to confirm that less than 50 V is
present between all power terminals and between power terminals and
earth.
•Unless otherwise stated, this product must NOT be dismantled. In the
event of a fault the inverter must be returned. Refer to "Routine
Maintenance and Repair".

Safety & EMC Requirements
Where there is a conflict between safety and EMC requirements, personnel safety shall always take
precedence.
Safety
WARNING!
Ignoring the following may result in injury or
damage to equipment:
•Never perform high voltage resistance checks on the wiring without
first disconnecting the inverter from the circuit being tested.
•Whilst ensuring ventilation is sufficient, provide guarding and /or
additional safety systems to prevent injury or damage to equipment.
•When replacing an inverter in an application and before returning to
use, it is essential that all user defined parameters for the product’s
operation are correctly installed.
•When replacing an inverter in an application and before returning to
use, it is essential that all user defined parameters for the product’s
operation are correctly installed.
•All control and signal terminals are SELV, i.e. protected by double
insulation. Ensure all external wiring is rated for the highest system
voltage.
•Thermal sensors contained within the motor must have at least basic
insulation.
•All exposed metalwork in the Inverter is protected by basic insulation
and bonded to a safety earth.
•RCDs are not recommended for use with this product but, where their
use is mandatory, only Type B RCDs should be used.
EMC
WARNING!
Ignoring the following may result in injury or
damage to equipment:
•In a domestic environment this product may cause radio interference in
which case supplementary mitigation measures may be required.
•This equipment contains electrostatic discharge (ESD) sensitive parts.
Observe static control precautions when handling, installing and
servicing this product.
•This is a product of the restricted sales distribution class according to
IEC 61800-3. It is designated as “professional equipment” as defined in
EN61000-3-2 for AC20F: Frame sizes 2 (excluding 1ø 2.2 kW), & 3
(400 V products only). Permission of the supply authority shall be
obtained before connection to the public low voltage supply.
For all other Frame sizes not specified above, connection to the public
LV supply must be agreed case by case between manufacturer,
installer or user and distribution network operator.

Application Risk & Risk Assessment
ApplicationRisk
CAUTION!
•The specifications, processes and circuitry described herein are for
guidance only and may need to be adapted to the user’s specific
application.
•Parker cannot guarantee the suitability of the equipment described in
this Manual for individual applications.
Risk Assessment
CAUTION!
•Under fault conditions, power loss or unintended operating conditions,
the inverter may not operate as intended. In particular:
oStored energy might not discharge to safe levels as quickly as
suggested and can still be present even though the inverter
appears to be switched off.
oThe motor's direction of rotation might not be controlled.
oThe motor speed might not be controlled.
oThe motor might be energized.
•An inverter is a component within an inverter system that may
influence its operation or effects under a fault condition. Consideration
must be given to:
oStored energy
oSupply disconnects
oSequencing logic
oUnintended operation

4 Introduction
4.1 About this Hardware Installation Manual
Users
This Manual is intended for use by the installer of the AC20F series Inverters. It assumes a reasonable
level of understanding in this discipline.
There is a separate Software Reference Manual –MSG11-5715-744/EN “AC20F Series –Software
Reference Manual”, that is intended for use by the user and programmer of the AC20F series Inverters.
Manual Organization
This Hardware Installation Manual is organized into chapters, indicated by the numbering on the edge of
each page.
If the manual is to be printed, it is designed so that it should be printed double-sided using the long-edge for
binding.
The Manual is ordered in a sequence that takes the user through the product installation process, resulting
in the basic operation of the drive.
Information for the full AC20F product is referred to as “the Inverter” or “drive” throughout the manual.
Product coding: Any “x” within a product code indicates there are variants. See ‘Chapter 12: AC20F Series
Product Codes’ section for more information.
Manual Revision
This revision replaces all previous revisions of this document. Parker has made every effort to ensure that
this document is complete and accurate at the time of printing. In accordance with our policy of continuous
product improvement, all data in this document is subject to change or correction without prior notice.
