Notes

Note the following points when you assemble the drive unit:

• Before setting up the drive unit, perform the steps according to chapter Installation notes.
• Only mount the drive unit to the system structure together with a torque arm. Installation without a torque arm is not permitted.
• Thoroughly remove any anti-corrosion agent from the shaft end. Use a commercially available solvent. Do not allow the solvent to penetrate the bearings and sealing rings as this could damage the material.
• Align the motor carefully to avoid placing any unacceptable strain on the motor shafts
• Do not jolt or hammer the shaft end.
• Ensure sufficient clearance around the unit to allow for adequate cooling air supply. Warm outlet air of other units must not affect the cooling.
• Use suitable cable glands for the supply leads (use reducing adapters if necessary).
• Seal the cable bushing properly.
• 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.
