2.1General notes on the product description

Ambient temperature Gear units and gearmotors from SEW-EURODRIVE can be operated in a wide ambienttemperature range. The following standard temperature ranges are permitted for fillingthe gear units according to the lubricant table: The rated data of the gear units and gearmotors specified in the catalog/price catalogrefer to an ambient temperature of +25 °C.Gear units and gearmotors from SEW-EURODRIVE can be operated outside the stan-dard temperature range if project planning is adapted to ambient temperatures from aslow as -40 °C in the intensive cooling range until up to +60 °C. Project planning musttake special operating conditions into account and adapt the drive to the ambient condi-tions by selecting suitable lubricants and seals. This kind of project planning is generallyrecommended for increased ambient temperatures as of size 97 and for helical-wormgear units with small gear ratios. SEW-EURODRIVE will gladly perform this project plan- ning for you.If the drive is to be operated on a frequency inverter manufacturers, you must also consider the projectplanning notes of the industrial inverter and the thermal effects of inverter operation.
Gear unit Filled with Permitted standard temperature rangeHelical, parallel shaft helical and heli-cal-bevel gear units CLP(CC) VG220-10 °C ... +40 °C Helical-worm gear units CLP(CC) VG6800 °C ... +40 °C Spiroplan ® gear units CLP(SEW-PG) VG460-10 °C ... +40 °C Installation altitude Due to the low air density at high installation altitudes, heat dissipation on the surface ofmotors and gear units decreases. The rated data listed in the catalog/price catalog ap-plies to an installation altitude of maximum 1000 m above sea level. Installation altitudes of more than 100 m asl must be taken into account for project planning of gear units andgearmotors. Power and torque The power and torque ratings listed in the catalogs refer to mounting position M1 andsimilar mounting positions in which the input stage is not completely submerged in oil.In addition, the gearmotors are assumed to be standard versions with standard lubrica-tion and under normal ambient conditions.Please note that the motor power shown in the selection tables for gearmotors is subjectto selection. However, the output torque and the desired output speed are essential forthe application and need to be checked. Speeds The quoted output speeds of the gearmotors are recommended values. You can calcu-late the rated output speed based on the rated motor speed and the gear unit ratio.Please note that the actual output speed depends on the motor load and the supply sys-tem conditions. Noise levels The noise levels of all SEW-EURODRIVE gear units, motors and gearmotors are wellwithin the maximum permitted noise levels set forth in the VDI guideline 2159 for gearunits and IEC/EN60034 for motors.
