Warning
This list does not claim to be exhaustive.
It may be necessary to make additional checks and tests corresponding to the
actual plant/system situation.
After assembling the motor in line with technical requirements and before
commissioning the system, check that:
•= the motor has been assembled and aligned properly.
•= the operating conditions are in accordance with the data specified on the
nameplate.
•= any supplementary motor monitoring devices and equipment have been
correctly connected and are functioning.
•= appropriately configured control functions and speed monitoring equipment
ensure that speeds higher than the permissible speeds stated on the rating
plate do not arise.
•= the power take-off elements have the correct parameters for their type (e.g.
alignment and balancing of couplings, belt tension of a belt drive, backlash and
crest clearance of a gear PTO drive, radial clearance).
•= the minimum insulation resistance values are complied with.
•= the earthing and equipotential grounding connections have been correctly
made.
•= all mounting screws, connecting elements and electrical connections are tight.
•= the rotor can be spun without coming into contact with the stator.
•= all shock protection measures for moving and live parts have been taken.
•= if the second shaft end has not been used, its featherkey has been secured to
prevent it being thrown out.
•= all separately driven fans fitted are ready for operation and have been
connected such that they rotate in the direction specified.
•= the flow of cooling air is not impeded.
•= brakes (if fitted) function perfectly.
