EMC notes for the application of the product standard EN 61800-3
The electromagnetic compatibility describes – according to the definition of the EMC directive – the "capability of a device to work satisfactorily in an electromagnetic environment without itself causing electromagnetic interference which is unacceptable for other devices present in this environment". To rantee that the appropriate EMC standards are observed, the devices must demonstrate a sufficiently high noise immunity, and also the emitted interference must be limited to acceptable values.
Product standard EN 61800‑3 describes the EMC requirements placed on "Variable-speed drive systems".
A variable-speed drive system (or Power Drive System PDS) consists of the Control Unit and Power Module or Control Unit, Line Module and Motor Module plus the relevant electric motors and encoders including connecting cables.
The driven machine is not part of the drive system.
EN 61800‑3 defines different requirements depending on the location where the drive is installed, designated as a first and second environment. Residential buildings or locations where the drive system is directly connected to a public low-voltage supply without intermediate transformer are defined
as the first environment. All locations outside a residential area are defined
as the second environment. These are basically industrial areas which are supplied from the medium-voltage network via their own transformers.
Four different categories are defined in EN 61800‑3 depending on the installation site of the drive:
Category C1: Drive systems for rated voltages < 1000 V for unlimited use in the first environment.
Category C2: Stationary drive systems for rated voltages < 1000 V for use in the second environment. Use in the first environment is possible if the drive system is operated and installed by qualified personnel. The warning information and installation instructions supplied by the manufacturer must be observed.
Category C3: Drive systems for rated voltages < 1000 V for exclusive use in the second environment.
Category C4: Drive systems for rated voltages ≥ 1000 V, for rated currents ≥ 400 A or IT supply systems for use in complex systems in the second environment. An EMC plan must be drawn up.
SINAMICS S120 Power Drive Systems (PDS) can be operated in the first and second environments. The measures necessary for operation in the respective environment are subsequently listed.
Interference immunity
The SINAMICS S120 drive system is suitable for operation in the second environment.
Regarding interference immunity, SINAMICS S120 can be used in the first and second environments.
Interference emission – complying with Category C2 second environment
Regarding interference emission, to comply with the limit values according to EN 61800‑3 second environment, Category C2, the following measures must be applied:
The drive system must be installed in compliance with EMC regulations by appropriately trained professionals.
The SINAMICS S120 drive system requires a radio interference suppression filter, Category C2 (integrated as line filter, or as optional external line filter with/without line reactor)
The pulse frequency is less than or equal to the rated pulse frequency
The maximum motor cable length is complied with (shielded)
Line supply with grounded neutral point (TN/TT supply system)

1) Selection and ordering data for line filters and line reactors, see sections Line-side power components.
2) Refers to the pulse frequency of the Motor Modules.
Interference emission – complying with Category C3 second environment
All Active Line Modules in booksize format, Basic Line Modules in booksize format 100 kW as well as Line Modules in chassis format in the standard version are compliant.
A line reactor is required for Power Modules in chassis format.
The maximum cable lengths and pulse frequencies (see the previous table) must be taken into account.
For Active Line Modules in booksize format, when using an external line filter, the maximum cable length can be increased to 1000 m (3281 ft).
Interference emission – complying with Category C4 second environment
When connected to IT line supplies, only devices without integrated filter, Basic Line Modules in booksize format up to 40 kW, and all Smart Line Modules in booksize format are permissible. To limit symmetrical interference emission, suitable external filters without capacitors connected to ground must be used.

Only PM240‑2 Power Modules in blocksize format can be used in the first environment.
Interference immunity
The SINAMICS S120 drive system is suitable for operation in the second environment.
Regarding interference immunity, SINAMICS S120 can be used in the first and second environments.
Interference emission – complying with Category C2 first environment
For use in the first environment, in addition to the requirements for use in the second environment, device-specific notes to maintain the harmonic current limits must be taken into consideration. Here, EMC product standard EN 61800‑3 makes reference to the standards pertaining to harmonic currents: EN 61000‑3‑2 and EN 61000‑3‑12.
Device-specific notes for complying with harmonic current limit values according to EN 61000‑3
Power Modules with a power PN ≤ 1 kW
Complying with limit values according to EN 61000‑3‑2 cannot be ranteed in this case. The installation company or company operating professionally used devices must obtain authorization to connect the device to the low-voltage grid from the responsible power utility company.
Power Modules with a power PN > 1 kW and a rated input current Irated, input < 16 A
These devices are not subject to any limit values regarding the harmonic currents, and can therefore be connected to the public low-voltage grid without prior authorization.
Power Modules with a rated input current > 75 A
There are no applicable standards when installing these types of devices. However, it is recommended that the utility company (grid operator) be informed when connecting such a device.
Device-specific measures to comply with harmonic current limit values:
Power Modules in blocksize format with a rated input current Irated, input > 16 A and ≤ 75 A | Measures to comply with harmonic current limits according to EN 61000‑3‑12 | ||||
|---|---|---|---|---|---|
Rated power | Rated input current Irated, input | Supply voltage | Frame size | Line reactor uk = 4 % | Minimum short-circuit power SSC at the connection point of the customers plant or system |
3 ... 7.5 kW | 20.7 ... 37 A | 200 ... 240 V 3 AC | FSC | Required 1) | S SC ≥ 120 × √3 × Uline × Irated, input |
5.5 ... 15 kW | 17.2 ... 39.9 A | 380 ... 480 V 3 AC | FSB and FSC | Required 1) | |
11 ... 18.5 kW | 40 ... 64 A | 200 ... 240 V 3 AC | FSD | Not required | S SC ≥ 120 × √3 × Uline × Irated, input |
18.5 ... 37 kW | 36 ... 70 A | 380 ... 480 V 3 AC | FSD | Not required | |

Example of calculating the minimum short-circuit power required
Determining the minimum short-circuit power SSC for the Power Module in blocksize format FSD: 37 kW with Uline = 400 V and Irated, input = 70 A
S SC ≥ 120 × √3 × Uline × Irated, input
The short-circuit power must be greater than 120 × 1.73 × 400 V × 70 A = 5812 kVA
As guide value, this typically corresponds to a low-voltage transformer with an apparent power of approximately 300 ... 400 kVA.
Note:
The installation company or company operating the device is responsible for ensuring that this device is only connected at a connection point with an appropriate short-circuit power (fault level), if this is necessary after consulting the power utility (grid operator).
The installation company or company operating the device requires authorization from the power utility (grid operator) in the following situations:
Three-phase connection to a line supply with lower short-circuit power
Three-phase connection without a line reactor
Connecting single-phase devices with a rated input current Irated, input >16 A
The following load-side power components in the appropriate frame sizes are optionally available for the Power Modules and result in the following maximum cable lengths:

1) Further information is available on the Internet at //www./sinamics-g120/documentation
2) The values apply for cables with low capacitance, e.g. MOTION‑CONNECT. When using standard CY cables, the maximum motor cable length is 50 m (164 ft) (shielded).
3) For frame sizes FSD to FSF, the maximum permissible cable lengths are not increased with a motor reactor. By means of the motor reactor, the loading of the motor windings is reduced by lower rates of voltage rise (dv/dt).
