Mechanical And Electrical Check - Siemens SIMOTICS 1LE8 Operating Instructions Manual

Commissioning
7.1 Measures before commissioning
• All touch protection measures for both moving and live parts have been implemented.
• 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
motor.
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.
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.
7.1.2

Mechanical and electrical check

• 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 motor 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.
