Fundamental safety instructions

1.1

General safety instructions

WARNING

Risk of death if the safety instructions and remaining risks are not carefully observed

If the safety instructions and residual risks are not observed in the associated hardware

documentation, 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 indust

rial security functions that support the

secure operation of plants, solutions, machines, equipment and/or networks. They are

important components in a holistic industrial security concept. With this in mind, Siemens’

products and solutions undergo continu

ous development. Siemens recommends strongly

that you regularly check for product updates.

For the secure operation of Siemens products and solutions, it is necessary to take suitable

preventive action (e.g. cell protection concept) and integrate each comp

onent into a holistic,

state

-of-the-art industrial security concept. Third-party products that may be in use should

also be considered. For more information about industrial security, visit this address

(

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

To stay informed about product updates as they occur, sign up for a product

-specific

newsletter. For more information, visit this address (

http://support.automation.siemens.com

WARNING

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

Software manipulation (e.g. by viruses, Trojan horses, malware, worms) can cause unsafe

operating states to develop in your installation which can result in death, severe injuries

and/or material damage.

•Keep the software up to date.

You will find relevant information and newsletters at this address

(http://support.automation.siemens.com).

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

industrial security concept for the installation or machine.

You will find further information at this address

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

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

concept.

●Compact Operating Instructions in German and English

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

the inverter.

Reading the OSS license terms

The inverter contains open-source software (OSS). OSS comprises open source text and

satisfies special license terms. If you wish to read the license terms, you must transfer them

from the inverter to a PC.

Procedure

To transfer the OSS license terms from the inverter 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 8)

3. Switch on the inverter power supply.

4. When you have switched on the power supply, wait 30 seconds.

During this time, the inverter writes the "Read_OSS.ZIP" file onto the memory card.

5. Switch off the inverter power supply.

6. Withdraw the memory card from the inverter.

7. Use a card reader and load the file to a PC.

You have then transferred the OSS license terms from the inverter to a PC, and you can now

read the license terms.

Installing the Control Unit

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 PM240 FSGX Power Module

To insert or detach the Control Unit, you must r

elease the two screws

at the front cover, slightly shift the front cover upwards and remove

towards the front.

Reattach the front cover before you commission the device.

Permissible Power Modules

You may operate the Control Unit with the following Power Modules:

•

PM240

•

PM240-2

•

PM250

•

PM260

•

PM340 1AC

3.3

Terminal strips behind the upper front door

All terminals with reference potential "GND" are connected with one another in the inverter.

Terminals 31, 32

Connection of the optional 24 V supply has the following advantages:

•The Control Unit remains in operation after disconnection of the Power Module from the line sup-

ply. The Control Unit thus maintains the fieldbus communication, for example.

•You can use terminals 51 … 54 as digital outputs.

Power supplies in conformance with SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low

Voltage) are permissible.

If you use a common external power supply for terminals 31, 32 and the digital inputs, you must con-

nect GND and the reference potential of the digital input ("DI COM1/2/3") with each other.

Terminals 3, 4 and 10, 11: You may use the internal 10 V supply or an external power supply for the analog inputs. For

an internal 10 V supply: Connect AI 0, respectively AI 1- with GND.
