If the second shaft extension is not used:
● Carefully secure the feather key to prevent it from being thrown out, and for balancing
type "H" (standard type), ensure its weight is reduced to approximately 60 % of the
original value.
● Using covers, carefully secure the unused shaft extension so that it cannot be touched.
Risk of losing the IP degree of protection as a result of damaged shaft sealing rings
This can result in death, serious injury, or material damage.
● Replace damaged components immediately.
● Rotate the rotor to ensure that it does not touch the stator.
● Ensure that the bearing insulation is not bridged/jumpered.
● Using the appropriately designed and adjusted control and speed monitoring functions
ensure that the permissible speeds specified on the rating plate cannot be exceeded.
● Ensure that any supplementary equipment used to monitor the motor is correctly
connected and is functioning.
● Carefully check the grounding and potential bonding connections.
● Connect the machine corresponding to the specified direction of rotation.
● Using the appropriate open-loop control and speed monitoring functions, carefully ensure
that no higher speeds can be achieved than are permitted and specified in the technical
data. For this purpose, compare the data on the rating plate or, if necessary, the system-
specific documentation.
● Comply with the minimum insulation resistances.
● Comply with the minimum air clearances.
● Correctly connect possibly available machine monitoring devices and equipment - and
carefully ensure that they are functioning correctly.
● Check the correct functioning of the brakes or backstops.
● Set the values for "Alarm" and "Shutdown" at the monitoring devices.
● Carefully ensure that temperature-sensitive parts and components, e.g. cables are not in
contact with the machine enclosure.
● If the motor design requires connection to a specific converter type, carefully check the
supplementary data on the rating plate/supplementary plate.
● Carefully ensure that the converter is correctly parameterized. The parameterization data
is specified on the rating plate of the machine. Information about the parameters is
available in the operating instructions for the converter.
