Commissioning
7.1 Measures before commissioning
● Moving parts, for example the coupling, move freely.
● All touch protection measures for moving and live parts have been taken.
● Screwed-in lifting eyes are removed after installation or secured to prevent them from
becoming loose.
● Before commissioning, attach the covers to guarantee the correct air guidance.
● Ensure that all condensation drain holes are always located at the lowest part of the
machine.
Second shaft extension
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.
7.1.2
Mechanical checks
● 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.
Electrical connection
● 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.
