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 for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions. Qualified
personnel are those who, based on their training and experience, are capable of identifying risks and avoiding
potential hazards when working with these products/systems.

2.6 Interference immunity
By selecting suitable signal cables and evaluation units, companies operating complete plants
and systems must ensure that the interference immunity of the machine is not diminished.
2.7 Influence on the line power supply through a strongly irregular torque
A strongly irregular torque, for example with the drive of a reciprocating motor, forces a non-
sinusoidal motor current. The emerging harmonics can have an impermissible influence on
the line power supply via the connection lines.
2.8 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.
● Comply with the EMC information provided by the manufacturer of the converter. This is
how you prevent the limit values stipulated by IEC/EN 61000-6-3 for the drive system
(consisting of the machine and converter) from being exceeded.
● You must put appropriate EMC measures in place.

2.9 Electromagnetic fields when operating electrical power engineering
installations
WARNING
Interference to electronic devices caused by electrical power equipment
Electrical power equipment generate electric fields during operation. Potentially lethal
malfunctions can occur in medical implants, e.g. pacemakers, in the vicinity of electrical power
equipment. Data may be lost on magnetic or electronic data carriers.
● It is forbidden for people with pacemakers to enter the vicinity of the machine.
● Protect the personnel working in the plant by taking appropriate measures, such as
erecting identifying markings, safety barriers and warning signs and giving safety talks.
● Observe the nationally applicable health and safety regulations.
● Do not carry any magnetic or electronic data media.
