•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

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.

Lifting the Inverter
CAUTION!
HEAVY OBJECT
- Always ensure that all lifting equipment is suitably sized to support the
weight of the product.
- These models are heavy and will require the use of a forklift or hoist to
lift and install it into position.
- Pay attention to the centre of gravity of the product. This is marked on
the product packaging.
Frames2 –6:
These products can be lifted by an individual. Care must be taken when handling the products to avoid
injury.
Frame7:
A forklift, or two people, are required when handling this frame size. Again, care must be taken to avoid
injury.
This product will stand up vertically on a flat surface.
Frames8–10:
A forklift is required for handling these frame sizes. Lifting eyes are available for use during this process.
Hooks and lifting slings should be used to lift the inverter out of its packaging and to stand it up vertically on
a flat surface, before moving it to a new location:
1. Insert a lifting rod through the lifting
eyes at the top of the product.
2. Use a forklift to lift the inverter using
the lifting rod.
With the inverter hanging vertically on
the forklift with the lifting rod, it is now
free to be maneuvered into its
installation location.

Mounting the Inverter
These products are intended to be mounted vertically inside a suitable enclosure.
1. Mark out the fixing hole positions on the cubicle back
panel as per the Fixing Dimensions listed in the table
above.
2. Drill the fixing holes as per the Slot Size and required
Fixing as listed in the table above.
3. Screw the fixings part way into the cubicle back panel.
4. Lift the inverter into position (via suitable means) and onto
the fixings using the keystone slots at the top of the
product to hang the inverter into position.
5. Secure the product by fully tightening the fixings.
6. The inverter is now ready for wiring.

Ventilation Clearance Requirements
The inverter gives off heat in normal operation and must therefore be mounted to allow the free flow of air
through the ventilation slots and heatsink:
- Maintain minimum clearances for ventilation as given in the tables below to ensure adequate
cooling of the inverter, and that heat generated by other adjacent equipment is not transmitted to
the inverter.
- Be aware that other equipment may have its own clearance requirements.
- When mounting two or more inverters together, these clearances are additive.
- Ensure that the mounting surface is normally cool.
- The inverter must be mounted in a suitable cubicle.
