Safety information

2.10 Influence on the line power supply through a strongly irregular torque

2.10 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.

Interference voltages when operating the converter

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 limit values according to IEC/EN 61000-6-2 .... IEC/EN 61000-6-4 for the
drive system (consisting of the machine and converter) from being exceeded.
• You must put appropriate EMC measures in place.

Special designs and construction versions

Before carry out any work on the machine, determine the machine version.
If there are any deviations or uncertainty, contact the manufacturer, specifying the type
designation and serial number (see the rating plate), or contact the Service Center (Page 12).
2.13

Certificate with special conditions

The certificate with special conditions is provided under the Quality documents press
(Page 171). To do this, under field "Enter search term", enter the certificate number and
select the appropriate document from the documents that are listed.
The machine has an "X" marking (for EACEx in the Ex marking, for ATEX, IECEx and UKCA, in
the certificate number). To ensure safe operation in potentially explosive zones, the special
conditions of the certificate specified on the nameplate must be strictly complied with:
EPS 18 ATEX 1 202 X, EPS 18 ATEX 1 203 X, IECEx EPS 18.0104X, RU C-DE.AA81.B.00156-
19, EPS 21 UKEX 1 250 X, EPS 21 UKEX 1 255 X:
• It is not permissible to operate groups of motors connected to a converter. The rated
converter current may correspond as a maximum to twice the rated motor current. It is
only permissible to operate the motor with a SINAMICS converter or a converter that is
comparable. When commissioning the system, with reference to the rated voltage (UN) of
