3.4 Installation
Either tighten the eye bolts used for transport or remove them completely.
Protect the motor, rotating shafts and unused shaft ends against contact.
Secure unused shaft keys against being thrown out or remove them.
The top section of the terminal box can be rotated by 4 x 90 degrees.
For outdoor installation or vertical versions, such as V1 or V5 with the shaft facing downwards, a
double fan cover should be used (option: RDD).
Condensation drain holes must always be located at the lowest point of the motor. If the motor is
designed with closed condensation outlets (option: KB), make sure that they are closed. Open
condensation drain holes would cause a reduction of the protection class.
3.5 Installation
3.5.1 Installation of driven elements
Attachments must not impair the flow of cooling air necessary for cooling. The driven elements must
not rub.
Always mount and dismount the driven elements (coupling, pulleys, gear wheel, etc.) using a suitable
device.
Apply the required touch guard of the driven elements. If a motor is put into operation without a driven
element, secure the shaft key against being thrown out or remove the key. This also applies for any
second shaft end.
3.5.2 Alignment
Align the shafts of the motor and the driven machinery axially and radially exactly to each other,
especially in case of direct coupling. Incorrect alignment may result in damage to the bearings,
excessive vibration and breakage of the shaft.
3.5.3 Balancing
As standard, the rotors are balanced with half key balancing. Observe the appropriate form of
balancing if driven elements are installed on the motor shaft.
Driven elements must be balanced according to DIN ISO 1940.
In order to achieve smooth vibration-free running, align the coupling exactly and balance the drive
element correctly (coupling, pulleys, fans etc.). Complete balancing of the motor and the driven
element may be necessary.
3.5.4 Fasten the flanged bearing plate
WARNING
Electric shock
If the fastening screws used are too long, the motor winding may be damaged. This creates a danger
of potential transfer to the housing which may lead to an electric shock when touching.
• Use fastening screws that do not exceed the maximum insertion depth of 2 x d.
