Warning notice system

This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent

damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert

symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are

graded according to the degree of danger.

DANGER

indicates that death or severe personal injury will result if proper precautions are not taken.

WARNING

indicates that death or severe personal injury may result if proper precautions are not taken.

CAUTION

indicates that minor personal injury can result if proper precautions are not taken.

NOTICE

indicates that property damage can result if proper precautions are not taken.

If more than one degree of danger is present, the warning notice representing the highest degree of danger will

be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to

property damage.

Qualified Personnel

The product/system described in this documentation may be operated only by

personnel qualified

Fundamental safety instructions

1.1

General safety instructions

WARNING

Danger to life if the safety instructions and residual risks are not observed

If the safety instructions and residual risks in the associated hardware documentation are

not observed, accidents involving severe injuries or death can occur.

•Observe the safety instructions given in the hardware documentation.

•Consider the residual risks for the risk evaluation.

WARNING

Danger to life or malfunctions of the machine as a result of incorrect or changed

parameterization

As a result of incorrect or changed parameterization, machines can malfunction, which in

turn can lead to injuries or death.

•Protect the parameterization (parameter assignments) against unauthorized access.

•Respond to possible malfunctions by applying suitable measures (e.g. EMERGENCY

STOP or EMERGENCY OFF).

Industrial security

Note

Industrial security

Siemens provides products and solutions with industrial security functions that support the

secure operation of plants, systems, machines and networks.

In order to protect plants, systems, machines and networks against cyber

threats, it is

necessary to implement

– and continuously maintain – a holistic, state-of-the-art industrial

security concept. Siemens products and solutions only represent one component of such a

concept.

The customer is responsible for preventing unautho

rized access to its plants, systems,

machines and networks. Systems, machines and components should only be connected to

the enterprise network or the internet if and to the extent necessary and with appropriate

security measures (e.g. use of firewalls and

network segmentation) in place.

Additionally, Siemens’ guidance on appropriate security measures should be taken into

account. For more information about industrial security, please visit:

Industrial security (

http://www.siemens.com/industrialsecurity).

Siemens’ products and solutions undergo continuous development to make them more

secure. Siemens strongly recommends to apply product updates as soon as available and to

always use the latest product versions. Use of product versions that are no longer supported,

and failure to apply latest updates may increase customer’s exposure to cyber threats.

To stay informed about product updates, subscribe to the Siemens Industrial Security RSS

Feed at:

ndustrial security (http://www.siemens.com/industrialsecurity).

WARNING

Danger to life as a result of unsafe operating states resulting from software manipulation

Software manipulations (e.g. viruses, trojans, malware or worms) can cause unsafe

operating states in your system that may lead to death, serious injury, and property

damage.

•Keep the software up to date.

•Incorporate the automation and drive components into a holistic, state-of-the-art

industrial security concept for the installation or machine.

•Make sure that you include all installed products into the holistic industrial security

concept.

•Protect files stored on exchangeable storage media from malicious software by with

suitable protection measures, e.g. virus scanners.

●Compact Operating Instructions in German and English

●The inverter contains open-source software (OSS). The OSS license terms are saved in

the inverter.

Transferring OSS license terms to a PC

Procedure

To transfer OSS license terms to a PC, proceed as follows:

1. Switch off the inverter power supply.

2. Insert an empty memory card into the card slot of the inverter.

Overview of the interfaces (Page 9)

3. Switch on the inverter power supply.

4. The inverter writes file "Read_OSS.ZIP" to the memory card within approximately

30 seconds.

5. Switch off the inverter power supply.

6. Withdraw the memory card from the inverter.

7. Insert the memory card into the card reader of a PC.

8. Please read the license terms.

You have transferred the OSS license terms to a PC.

Installing the Control Unit - General

Each Power Module has an appropriate holder for the Control Unit and a release

mechanism.

Inserting the Control Unit

Proceed as follows to plug the Control

Unit onto a Power Module:

Place the two catches of the

Control Unit in the matching

grooves of the Power Module.

Press the Control Unit onto the

Power Module until you hear that it

latches.

You have now plugged the Control

Unit onto the Power Module.

Removing the Control Unit

Remove the Control Unit from the Power Module by pressing the release mechanism.

Special features for the PM230 Power Module IP55, FSA … FSC

To insert or detach the Control Unit, you must

release eight

or ten fixing screws of the cover

and then remove the cover.

The Power Module release mechanism is

shown in the diagram.

Attach the cover again before you commission

the inverter. Do not damage the seal of the

cover when attaching it.

Adapter for operating a PM230 IP55 Power Module

For operating the Control Unit with a PM230 IP55 Power Module, FSA … FSC, an adapter is

required between the Control Unit and operator panel (BOP-2 or IOP).

The adapter, which is included in the scope of delivery of the Power Module, is too short for

the CU240E-2 Control Unit. The matching adapter for the CU240E-2 Control Unit can be

ordered through the KnorrTec company.

Wiring the terminal strip in compliance with EMC

●If you use shielded cables, then you must connect the shield to the mounting plate of the

control cabinet or with the shield support of the inverter through a good electrical

connection and a large surface area.

●Use the shield connection plate of the Control Unit as shield support and strain relief.
