Certification
Requirements for United States/Canadian installations (UL/cUL)
Suitable for use on a circuit capable of delivering not more than 65000 rms Symmetrical
Amperes, 480 VAC maximum, when protected by UL/cUL-listed Class J fuses or circuit
breakers. For each frame size AA, A, B, and C, use 75 °C copper wire only.
This equipment is capable of providing internal motor overload protection according to
UL508C.
For Canadian (cUL) installations the drive mains supply must be fitted with any external
recommended suppressor with the following features:
• Surge-protective devices; device shall be a Listed Surge-protective device (Category
• Rated nominal voltage 480/277 VAC, 50/60 Hz, 3-phase
• Clamping voltage VPR = 2000 V, IN = 3kA min, MCOV = 508 VAC, SCCR = 65 kA
• Suitable for Type 2 SPD application
• Clamping shall be provided between phases and also between phase and ground.
Harms to human health from electromagnetic radiation
This product may cause high-frequency electromagnetic radiation, which will affect human
health. Therefore, in a residential environment, make sure that necessary suppression
measures are taken.
Note
EMC instructions
• To comply with the EMC standards, all cables connected with the SINAMICS V90 system
must be shielded cables, which include cables from the line supply to the line filter and
from the line filter to the SINAMICS V90 drive.
• The SINAMICS V90 drives have been tested in accordance with the emission
requirements of the category of C2 (domestic) environment. The conductive emissions
and radiated emissions are in compliance with the standard of EN 55011 and reached
Class A.
• In a residential environment, this product can cause high-frequency interferences that
may necessitate suppression measures.
• For a radiated emission test, an external AC filter (between the mains supply and the
drive) will be used to meet the EMC requirement and the drive will be installed inside the
shielded metallic chamber, other parts of the motion control system (including the PLC,
DC power supply, spindle drive, motor) will be put inside the shielded chamber.
• For a conductive emission test, an external AC filter (between the mains supply and the
drive) will be used to meet the EMC requirement.
• For the radiated emission and conductive emission test, the length of the line supply
cable between the line filter and the drive must be shorter than 1 m.
