2Safety notes

2.1 Information for those responsible for the plant

or system

This electric machine has been designed and built in accordance with the

specifications contained in Directive 2006/95/EC up to April 19, 2016 - and from April

20, 2016 according to Directive 2014/35/EU ("Low-Voltage Directive") and is intended

for use in industrial plants. Please observe the country-specific regulations when

using the electric machine outside the European Community. Follow the local and

industry-specific safety and setup regulations.

The persons responsible for the plant must ensure the following:

●Planning and configuration work and all work carried out on and with the machine

is only to be done by qualified personnel.

●The operating instructions must always be available for all work.

●The technical data as well as the specifications relating to the permissible

installation, connection, ambient and operating conditions are taken into account

at all times.

●The specific setup and safety regulations as well as regulations on the use of

personal protective equipment are observed.

Note

Use the services and support provided by the appropriate

Service Center

(Page

145) for planning, installation, commissioning, and servicing work.

You will find safety instructions in the individual sections of this document. Follow the

safety instructions for your own safety, to protect other people and to avoid damage

to property.

Observe the following safety instructions for all activities on and with the machine.

2.2 Additional information: Information for plant

managers (ATEX)

This machine has been designed and built in accordance with Directive 94/9/EC until

April 19, 2016 and from April 20, 2016 in accordance with Directive 2014/34/EU

("Explosion Protection Directive”), and it is intended for use in industrial plants with a

potentially explosive atmosphere.

Commissioning in the European Community in accordance with Directive

2006/42/EU (“Machinery Directive”) is forbidden until the plant into which the

machine will be installed has been shown to conform with this directive. Please

observe the country-specific regulations when using the machine outside the

European Community.

WARNING

Commissioning prior to establishing conformance

If the machine is commissioned prior to determining the plant conformance, the

explosion protection of the plant is not ensured. An explosion can occur. This can

result in death, serious injury or material damage.

Do not commission the machine until it has been confirmed that the plant conforms

with the explosion protection directive.

2.3 The five safety rules

For your own personal safety and to prevent material damage when carrying out any

work, always observe the safety-relevant instructions and the following five safety

rules according to EN 50110-1 "Working in a voltage-free state". Apply the five safety

rules in the sequence stated before starting work.

Five safety rules

1. Disconnect the system.

Also disconnect the auxiliary circuits, for example, anti-condensation heating.

2. Secure against reconnection.

3. Verify absence of operating voltage.

4. Ground and short-circuit.

5. Provide protection against adjacent live parts.

To energize the system, apply the measures in reverse order.

CAUTION

Hazardous substances

Chemical substances required for the setup, operation and maintenance

of machines can present a health risk.

Poisoning, skin damage, cauterization of the respiratory tract, and other

health damage may result.

•Read the information in these operating instructions and the product

information supplied by the manufacturer.

2.6 Interference voltages when operating the

converter

WARNING

Interference voltages when operating the converter

When a converter is in operation, the emitted interference varies in strength

depending on the converter (manufacturer, type, interference suppression

measures undertaken). On machines with integrated sensors (e.g. PTC

thermistors), interference voltages caused by the converter may occur on the

sensor lead. This can cause faults which can result in eventual or immediate death,

serious injury or material damage.

Observe the EMC instructions of the converter manufacturer in order to avoid

exceeding the limit values according to IEC/EN 61000-6-3 for drive systems

comprising machine and converter. You must put appropriate EMC measures in

place.

Note

The increased level of danger in haz

ardous areas demands that you pay particular

attention to the notes marked with

2.7 Special conditions for explosion-proof

machines

Special conditions for the safe use of explosion-protected machines with Xmarking

(excerpt from EC or EU prototype test certificate, Point 17).

Zone 21

●Do not operate the motors with excessively thick deposits of dust.

●When the motors are mounted with the free shaft end pointing upwards, prevent

foreign bodies from dropping into the ventilation openings using an appropriate

mechanical design.

●For motors with a fixed connecting cable: The free end of the cable must be

connected according to valid regulations for electrical installations.
