Technical specifications (continued)

Compliance with standards

CE mark

The SINAMICS G120 inverters meet the requirements of the

Low-Voltage Directive 73/23/EEC.

Low-voltage directive

The inverters comply with the following standards listed in the

EU gazette:

• EN 60204

Safety of machinery, electrical equipment of machines

• EN 61800-5-1

Electrical power drive systems with variable speed – Part 5-1:

Requirements regarding safety – electrical, thermal, and en-

ergy requirements

UL listing

Converter devices in UL category NMMS certified to UL and

cUL, in compliance with UL508C. UL list numbers E121068 and

E192450.

For use in environment with contamination degree 2.

Machinery directive

The devices are suitable for installation in machines. Compli-

ance with the machinery directive 98/37/EEC requires a sepa-

rate certificate of conformity. This must be provided by the plant

constructor or the installer of the machine.

EMC directive

• EN 61800-3

Variable-speed electric drives

Part 3: EMC product standard including specific test methods

The modified EMC product standard EN 61800-3 for electrical

drive systems is valid since 07/01/2005. The transition period for

the predecessor standard EN 61800-3/A11 from February 2001

ended on October 1, 2007. The following information applies to

the SINAMICS G120 frequency inverters from Siemens AG:

• The EMC product standard EN 61800-3 does not apply di-

rectly to a frequency inverter but to a PDS (Power Drive Sys-

tem), which comprises the complete circuitry, motor and ca-

bles in addition to the inverter.

• Frequency inverters are normally only supplied to experts for

installation in machines or systems. A frequency inverter must,

therefore, only be considered as a component which, on its

own, is not subject to the EMC product standard EN 61800-3.

The inverter’s Instruction Manual, however, specifies the con-

ditions regarding compliance with the product standard if the

frequency inverter is expanded to a PDS. The EMC directive

in the EU is complied with for a PDS by observance of the

product standard EN 61800-3 for variable-speed electrical

drive systems. The frequency inverters on their own do not

generally require identification according to the EMC direc-

tive.

• In the new EN 61800-3 of July 2005, a distinction is no longer

made between “general availability” and “restricted availabil-

ity”. Instead, different categories have been defined, C1 to C4,

in accordance with the environment of the PDS at the operat-

ing site:

- Category C1: Drive systems for rated voltages < 1000 V for

use in environment 1

- Category C2: Stationary drive systems not connected by

means of a plug connector for rated voltages < 1000 V.

When used in environment 1, the system must be installed

and commissioned by personnel familiar with EMC require-

ments. A warning is required.

- Category C3: Drive systems for rated voltages < 1000 V for

exclusive use in environment 2. A warning is required.

- Category C4: Drive systems for rated voltages 1000 V, for

rated currents 400 A, or for use in complex systems in en-

vironment 2. An EMC plan must be created.

• The EMC product standard EN 61800-3 also defines limit val-

ues for conducted interference and radiated interference for

“environment 2” (= industrial power supply systems that do

not supply households). These limit values are below the limit

values of filter class A to EN 55011. Unfiltered inverters can be

used in industrial environments as long as they are installed in

a system that contains line filters on the higher-level infeed

side.

• With SINAMICS G120 Power Drive Systems (PDS) that fulfill

EMC product standard EN 61800-3 can be set up upon follow-

ing the setup instructions.

• A differentiation must be made between the product stan-

dards for electrical drive systems (PDS) of the range of stan-

dards EN 61800 (of which Part 3 covers EMC topics) and the

product standards for the devices/systems/machines, etc.

This will probably not result in any changes in the practical use

of frequency inverters. Since frequency inverters are always

part of a PDS and these are part of a machine, the machine

manufacturer must observe various standards depending on

their type and environment, e.g. EN 61000-3-2 for line har-

monics and EN 55011 for radio interference. The product

standard for PDS on its own is, therefore, either insufficient or

irrelevant.

• Regarding the compliance of limit values for line harmonics,

EMC product standard EN 61800-3 for PDS refers to compli-

ance with EN 61000-3-2 and EN 61000-3-12.

• Regardless of the configuration with SINAMICS G120 and its

components, the mechanical engineer can also implement

other measures to ensure that the machine complies with the

EU EMC directive. The EU EMC directive is generally fulfilled

when the relevant EMC product standards are observed. If

they are not available, the generic standards, e.g.

DIN EN 61000-x-x, can be used instead. It is important that

the conducted and emitted interferences at the line supply

connection point and outside the machine remain below the

relevant limit values. Any suitable technical means can be

used to ensure this.
