Setting up the drive unit

Notes
• Only install the DRC 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 end. Use a commercially
available solvent. Do not allow the solvent to penetrate the bearings and shaft seals
– 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 "DRC Gear-
motors" catalog.
• Do not jolt or hammer the shaft end.
• Ensure that cooling air supply is unobstructed and that air discharged by other units
does not influence cooling.
• Balance components that were subsequently mounted to the shaft with a half key
(output shafts are balanced with a half key).
• Use suitable cable glands for the supply leads (use reducing adapters if necessary).
• Seal the cable entry properly.
• Thoroughly clean the sealing surfaces of the DRC cover before re-assembly.
• 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.
