Drive
The motor speed is controlled using a converter. It has been optimized for operation with
SINAMICS low-voltage converters.
Other converters must comply with certain requirements: You can find more information in the
catalog or in the engineering documentation.
Efficiency requirement
According to EU Regulation (EC) No. 640/2009, the IE3 efficiency requirement for low-voltage
motors with a power of 7.5 kW to 375 kW for line operation has been in force since January 01,
2015.
From January 1, 2017, the IE3 efficiency requirement for motors with a power of 0.75 kW to
375 kW applies for line operation.
Efficiency IE2 still applies for motors that are operated from a converter.
Please note the applicable country-specific rules and regulations.
NOTICE
Destruction of the machine when operated directly from the line supply
The machine will be destroyed if it is directly connected to the line supply. Only operate the
machine using a converter.
Cooling
The cooling system is designed as a closed, internal cooling circuit. The mounted cooler is an
air-to-water heat exchanger with a pipe system. The heat lost from the machine is dissipated
via the surface of the cooling pipes to the cooling liquid flowing in the pipes. External fans
facilitate the circulation of the cooling air in the primary circuit.
Leakage-water sensor
The leakage-water sensor is fitted externally on the machine enclosure and provides additional
security in the event of leakage.
Degree of protection
The machine is available with degree of protection IP55.
