MOUNTING

The motor should be securely mounted on a bed plate, base or platformthat is rigid enough to prevent any vibration of the unit and also preventtransfer of vibration to the unit. The base must not impose bending ortwisting strains on the housing.When mounting, we recommend the use of slotted shims as it may benecessary to remove or add shims when aligning shafts. The use of prop-er shims inserted under each mounting foot will prevent distortion of thehousing when the mounting bolts are secured. The following procedureis recommended when mounting the motor. 1.Add shims under the lowest mounting foot and tighten mounting foot bolt.2. Insert feeler gauges under the other mounting feet to determine amount ofshims required.3. Insert required shims under each mounting foot and tighten mountingbolts.4. Use a small number of thick shims rather than a large number of thinshims.5.Measure the alignment.
