Mechanical installation

Important notes

• Install the product according to the information in the chapter "Standards and operating conditions".
(Siehe Projektierungshandbuch)
• The technical data and the data regarding the supply conditions can be found on the nameplate and in
this documentation.
• Ambient media − especially chemically aggressive ones − may damage shaft sealing rings, lacquers and
plastics.
• Lenze offers special surface and corrosion protection in this case.

Transport

The transport weights can be found in the shipping documents!
The motors mounted on the gearbox are sometimes equipped with ears. These are exclusively
intended for mounting the motor on/removing the motor from the gearbox and must not be used
for the complete geared motor!
CAUTION!
Danger from tipping or falling loads!
Standing beneath suspended loads is prohibited!
▶ Use additional appropriate lifting aids, if required, to achieve a direction of loading which is as vertical as
possible (highest load carrying capacity). Secure lifting aids against shifting!
▶ Screw in the transport aids completely. They must have even and full-surface contact!
▶ Transport aids must be loaded vertically in the direction of the screw axis! Diagonal or lateral tension
reduces the load carrying capacity! Observe data in standard DIN 580!
Preparation
How to prepare the product for mounting:
• Protect shaft sealing rings from contact with solvents.
• Remove protection covers from shafts.
• Thoroughly remove anticorrosion agents from the shaft and from flange faces.
• Draw the transmission elements onto the output shaft only by using the centering thread.
• Align the output shaft and transmission elements exactly to avoid tensions.
• Mount belt pulleys, sprockets, or gear wheels as close as possible to the shaft shoulder in order to keep
the bending load of the shaft and the bearing forces at a minimum level.
• Tighten all screw connections with the specified torques and secure them with standard screw locking
adhesive.
• Check paint for damage and repair professionally.
