WOODWARD 8200-1300 governor

SIMODRIVE infeed units are designed to be connected to line supplies with compatibility level, Class 3 of electromagnetic environments in industrial plants and systems according to IEC/DIN EN61000–2–4:2002. When the EMC mounting/installation guidelines are complied with, noise immunity values according to IEC/DIN EN61000–6–2 Electromagnetic Compatibility (EMC) – Generic Standard, Noise Immunity/emission – Part 2: Industrial environments (1999) are complied with. The SIMODRIVE unit may be directly connected to TN line supplies with selectively tripping, AC/DC–sensitive RCCBs as protective measure. Upstream devices providing protection against hazardous leakage currents or for fire protection (such as residual–current protective devices) must be universal current–sensitive in accordance with the requirements of DIN EN 50178. In the case of other residual–current protective devices, a transformer with separate windings must be connected upstream of the converter for purposes of decoupling.

Points to bear in mind

 It is only permissible to use a delayed–tripping, (selective) AC/DC current–sensitive residual–current protective device (RCCB) (connection as shown in Fig. 7-1). Parts of the electrical equipment and machine that can be touched are integrated in a protective grounding system. It is not possible to connect RCCBs in series in order to implement selective tripping. The max. permissible ground resistance of the ”selective protection device” must be observed (83 Ω max. for RCCBs with a rated differential current In = 0.3 A). The total length of the shielded power cables used in the drive group (motor cable, incl. supply cables from supply system filters to the NE connection terminals) is less than 350/500 m for sinusoidal/squarewave current. Operation is only permitted with line filters. Only the line filters described in Chapter 7 may be used.

If a fault current protective device is used on the line supply side of this electronic device for protection in case of direct or indirect contact, only Type B is permitted! Otherwise, another protection measure must be applied, such as separating the electronic device from the environment through double/reinforced insulation or separating the electronic device from the line supply through a transformer.

Harmonics fed back into the line supply/noise emission

When the requirements regarding system fault level are observed and when using the appropriate line supply filters, the harmonics fed back into the line supply lie below the compatibility level of Class 3 of the electromagnetic environment of industrial plants and systems according to EN61000–2–4:2002. When the recommended SIEMENS line filter is used and the EMC mounting/ installation regulations are complied with, the noise emission limits according to EN50081–2 Electromagnetic Compatibility (EMC) – Generic Standard, Noise Immunity/emission – Part 2: Industrial environments (1993) are complied with. Notice If line filters are used that SIEMENS has not certified for use with SIMODRIVE 6SN11xx/6SLxx, this can result in harmonics being fed back into the line supply. These harmonics can damage/disturb other equipment connected to this line supply. Certification, e.g. CE is invalid. Certificates from Siemens are invalid, for example CE , UL. You are responsible for generating/obtaining the certificates for this new combination. It is not permissible to connect additional loads after the line filter
