Variant dependent options.

EMC filter, Class A.
Filter for inverters without an internal filter for 
- 3 AC 200 V to 240 V, frame sizes A and B 
- 3 AC 380 V to 480 V, frame size A, FX, GX
Filters for frame sizes FX and GX are only permitted to be used in combination with a line commutating choke. All other inverters with the exception of inverters for 500 V to 600 V can be supplied with an internal Class A filter. The requirements are fulfilled using shielded cables with a max. length of 25 m.
EMC filter, Class B.
Filter for inverters without an internal filter for 
- 3 AC 200 V to 240 V, frame sizes A and B 
- 3 AC 380 V to 480 V, frame size A.
The requirements are fulfilled using shielded cables with a max. length of 25 m. For inverters 15 kW to 75 kW without filters, EMC filters of Class B from Schaffner can be used. The requirements are fulfilled using shielded cables with a max. length of 25 m to 50 m (depending on the type, details on request). With this filter, the inverter complies with the emission standard EN 55 011, Class B for conducted interference emissions.
Additional EMC filter, Class B.
Available for inverters with an internal Class A EMC filter, frame sizes A, B and C. The requirements are fulfilled using shielded cables with a max. length of 25 m. With this filter, the inverter complies with the emission standard EN 55 011, Class B for conducted interference emissions.
Filter Class B with low leakage currents.
EMC filter for 1 AC 200 V to 240 V inverters, frame sizes A and B, without an internal EMC filter Class A. With this filter, the inverter complies with the emission standard EN 55 011, Class B for conducted interference emissions. The leakage currents are reduced to < 3.5 mA. The requirements are fulfilled using shielded cables with a max. length of 5 m.
Leakage currents: The leakage currents of the inverters with/without filter (internal/external) may exceed 30 mA. Typical values in practice are between 10 mA and 50 mA. The exact values depend on the design, environment and cable lengths. Interference-free operation with residual current operated devices with a trigger value of 30 mA cannot be guaranteed. However, operation with residual current circuit-breakers with a trigger value of 300 mA is possible. Please refer to the Instruction Manual for details.
LC filter and sinusoidal filter.
The LC filter/sinusoidal filter limits the rate of rise of voltage and the capacitive charge/ discharge currents which usually occur with inverter operation. This means that much longer shielded motor cables are possible when using LC filters/sinusoidal filters and the service life of the motor achieves values similar to those with direct mains operation. Use of an output choke isn’t required with that.
Please note when using LC filters/sinusoidal filters: 
- Only V/f, FCC control permissible 
- Please observe the derating of 15% when selecting the appropriate inverter 
- Operation only permissible with 4 kHz pulse frequency
Note: Please observe derating for frame sizes FX and GX. 
- The output frequency is limited to 150 Hz 
- Operation and commissioning only with connected motor as the LC filter/sinusoidal filter is not idling-proof! The LC filters/sinusoidal filters can be used for all MICROMASTER 440 inverters of frame sizes A to GX. 
- Frame sizes D to F: The LC filters, frame sizes D to F, are designed for mounting upright in the control cabinet. Due to leakage flux lines caused by physical sources, a minimum distance of 50 mm to adjacent modules and metal parts is recommended. 
- Frame sizes FX and GX: The sinusoidal filters, frame sizes FX and GX, are designed for mounting upright in the control cabinet. Due to leakage flux lines caused by physical sources, a minimum distance of 100 mm to adjacent modules and metal parts is recommended.
Line commutating choke.
Line commutating chokes are used to smooth voltage peaks or to bridge commutating dips. In addition, line commutating chokes reduce the effects of harmonics on the inverter and the power supply. If the line impedance is < 1 %, a line commutating choke must be used in order to reduce the current peaks. In line with EN 61 000-3-2 regulations “Limits for harmonic currents with device input current 16 A per phase”, there are special aspects for drives with 250 W to 550 W and 230 V single-phase supplies which can be used in non-industrial applications (1st environment). For devices with 250 W and 350 W, it is necessary either to fit the recommended input chokes or to apply to the power utility company for authorization to connect the devices to the public power supply. No limits are currently defined in the EN 61 000-3-2 standard for professionally used devices with a connected load >1 kW which means that the inverters with an output power  0.75 kW comply with the EN 61 000-3-2 standard. However, in accordance with the regulations of EN 61000-3- 12 “Limits for harmonic currents > 16 A and  75 A per phase” an approval is necessary from the power supplier for drives that are intended to be connected to the public low-voltage network. Please refer to the Operating Instructions for the values of the harmonic currents.
Output choke.
Output chokes can be supplied for reducing the capacitive compensation currents and dV/dt in the case of motor cables >50 m (shielded) or >100 m (unshielded). For max. permissible cable lengths, see the Technical Data.
Brake resistors.
The brake resistors are designed for use with the MICROMASTER 440 inverter series, frame sizes A to F, with internal brake chopper and enable loads with a large moment of inertia to be braked quickly. During braking of the motor and the load, excess energy is fed back to the inverter. This causes the voltage to rise in the DC link. The inverter transfers the excess energy to the externally mounted braking resistor. For MICROMASTER 440 inverters of frame sizes FX and GX, external SIMOVERT MASTERDRIVES brake units and the appropriate brake resistors can be used (see Catalog DA 65.10).
Gland plate.
Gland plates are available for inverters of frame sizes A, B and C. All the other frame sizes have the shield connection for the control cable integrated in the inverter. The shield for the power cable has to be connected externally (e.g. in the control cabinet). Exception: Inverters of frame sizes D and E and frame size F with integrated class A filter. In this case the shield connection is integrated in the inverter. The gland plate enables the shields of the power and control cables to be terminated ensuring optimum EMC performance.

Siemens vfd Micromaster 440 series general installation instructions.

- A maximum of two footprint components plus inverter are permissible. 
- If an LC filter is used, it must, if possible, be mounted directly on the wall of the control cabinet due to weight reasons. If an LC filter of frame size C is used, therefore, only one footprint component is permissible. If a line choke and LC filter are used, the line choke must be located on the left of the inverter. Required distance between line choke and inverter: 75 mm. 
- The EMC filter must be mounted directly below the frequency inverter if possible. 
- If mounted on the side, the line-side components are to be mounted to the left of the frequency inverter whereas the output-side components are to be mounted to the right of the frequency inverter. 
- If a braking resistor is used, it must, if possible, be mounted directly on the wall of the control cabinet due to reasons relating to temperature increases.
