ing gear is available. Observe the foundation and installation plan as well as the installation instructions for the Extruder. Mounting position and attachment points During the actual planning phase, be sure to allow for sufficient space around the gear unit to enable subsequent upkeep and maintenance work. Take suitable measures to ensure that unhindered convection across the housing surface is possible so that the gear unit does not overheat. Do not use incorrect attachment points ( Page . The position of the attachment points is shown in the dimension drawing or the transport drawing in the complete documentation for the gear unit. To ensure that the unit is properly lubricated during operation, please observe the mounting position specified in the dimension drawings. More information Further information about dimensions, space requirements and arrangement of supply con- nections can be found in the drawings in the complete documentation of the gear unit. Assembly 5.2 Unpacking the gear unit 3 Edition 0/2 A5-0 enNOTICE Heating of the gear unit by external heat sources The gear unit must not be heated by external heat sources (exposure to direct sunlight, for example) while it is in operation and measures must be taken where necessary to protect it. You can take the following measures to protect the gear unit against this hazard: sun shield An additional cooling device temperature monitoring device with trip function in the oil sump If you use sun shield, this may cause build-up of heat. If you use temperature monitoring device, it must be capable of issuing an alarm when the maximum permissible oil sump temperature is reached. It must also be capable of tripping the drive when the maximum permissible oil sump temperature is exceeded. The operator' process might be interrupted when the drive is shut down. WARNING Ignition of vapours emitted from solvents. There is risk of injury due to ignition of vapours emitted from solvents when carrying out cleaning
