Notes on installing the drive unit

Observe the following information when installing the drive unit:

• Perform the steps described in chapter Installation notes before installing the drive unit.
• Only install the drive unit on a level, low-vibration, and torsionally rigid support structure.
• Observe the mounting position specified on the motor nameplate.
• Thoroughly remove any anti-corrosion agent from the shaft ends. Use a commercially available solvent for this purpose. Do not allow the solvent to penetrate the bearings and sealing rings – this could damage the material.
• Align the motor carefully to avoid placing any unacceptable strain on the motor shafts. Observe the permitted overhung and axial loads specified in the respective gearmotor catalog.
• Do not jolt or hammer the shaft end.
• Ensure sufficient clearance around the unit to allow for unobstructed flow of cooling air. Warm exhaust air from other units must not affect the cooling.
• Balance the parts that were subsequently added to the shaft with a half key (output shafts are balanced with a half key).
• Thoroughly clean the sealing surfaces of the cover before reassembly.
• If the corrosion protection coating is damaged, restore the coating.
• Check whether the degree of protection specified in the operating instructions and on the nameplate is permitted in the ambient conditions on site.
• Observe the information of Directive VDI 2230-1 on determining the tightening torques for mounting the drive unit to the application.
