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

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 industrial security functi

ons 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 continuous development. Sie

mens 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 component into a holisti

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 Hotspot

-Text

(

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 Hotspot

-Text

(

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

●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. See also Section:

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.

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.

3.3

Terminal strips on CU240B-2 Control Units

Terminal strips with wiring example

All terminals labelled with reference potential "GND" are connected internally in the inverter.

Reference potential "DI COM" is electrically isolated from "GND".

→ If, as shown above, the 24 V supply from terminal 9 is used to supply the digital inputs, then you

must connect "GND" to "DI COM".

Terminals 31, 32

Reference potential "GND IN" is electrically isolated from "GND". When an optional 24 V power supply

is connected at terminals 31, 32, even when the Power Module is disconnected from the line supply,

the Control Unit remains in operation. The Control Unit thus maintains the fieldbus communication, for

example.

→ at terminals 31, 32, only connect a power supply that is in accordance with SELV (Safety Extra Low

Voltage) or PELV (Protective Extra Low Voltage).

→ if you use a common external power supply for terminals 31, 32 and the digital inputs, you must

connect "GND" to "GND IN".

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

→ If you use the internal 10 V power supply, you must connect AI 0- to GND.
