7.1.1 Checks to be carried out prior to commissioning
The following list of checks to be performed prior to commissioning does not claim to be
complete. It may be necessary to perform further checks and tests in accordance with the
specific situation on-site.
Once the system has been correctly installed, you should check the following prior to
commissioning:
•
The motor is undamaged.
• The motor has been properly installed and aligned.
• The output transmission elements are set correctly for their type,
e.g. alignment and balancing of couplings, belt forces in the case of a belt drive, tooth
forces and tooth-flank backlash in the case of geared output, radial and axial clearance in
the case of coupled shafts.
• All fixing screws, connection elements, and electrical connections have been tightened to
the specified tightening torques.
• The operating conditions match the data provided in accordance with the technical
documentation, such as degree of protection, ambient temperature, etc.
• Moving parts, for example the coupling, move freely.
• 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.
• Comply with the EMC guidelines when using the PT100/PT1000 sensors to ensure the
correct feedback signals from the sensors.
Note
The voltage in RTD terminals can be induced due to the magnetic interference between
the power cables and the signal cables. Therefore, the signals received can be false.
Touching the terminals directly can result in injury.
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.
