Complies with EMC guidelines defined in EN 61800?3 thanks to line filter which is integrated as standard (with grounded supply system)
Category C2 for compact units in TN/TT system of the first environment (residential area), category C1 available as an option
Category C3 for cabinet units (TN/TT system) of the second environment (industrial area)
Category C4 for compact and cabinet units in IT system of the second environment (industrial area)
SINAMICS G180 converters cause minor line harmonics: Thanks to line reactors integrated in cabinet units and DC reactors integrated in compact units
Output filter to permit the use of long motor cables for motors with standard insulation
Insulation monitoring for IT systems integrated in 500/690 V units and ground fault monitoring for TN and TT systems integrated in 400 V units
Wide range of input voltages
Lower additional motor noise emissions of typically 3 dB(A) as well as minor losses in converter and motor thanks to optimized pulse pattern and converter clock frequency
Units can be protected by standard fuses (gL characteristic)
Standardized user interface on units rated from 2.2 to 6 600 kW
Control section
High level of protection for personnel and plant is provided by protective separation of the safety extra-low voltage in accordance with IEC/EN 61800?5?1 at the analog and digital control inputs and outputs of the power unit.
Operation and settings
Straightforward to operate and set by means of a menu-assisted, 4-line plaintext display with membrane keyboard on the converter unit or remotely from the control room via an RS485 link at a distance of up to 1000 m
Extensive range of functions using a Windows-based PC operating program
Explosion protection
ATEX-certified tripping concept in accordance with Directive 94/9 EC for the safe operation of motors in hazardous zones 1 and 2, which means that no main contactor is required
Safe Torque Off
Available with options G04, G05, G08
Shutdown mechanism to prevent unexpected starting. Category 0 stop function in accordance with EN 60204?1 (stop by disconnection of power supply to the machine).
