... must never be technically changed.
... must never be commissioned in an incompletely mounted state.
... must never be operated without the required covers.
... may have live, moving or rotary parts during and after operation − corresponding
to their type of protection. Surfaces may be hot.
... must not be operated with great vibrations ....
... must not be operated in the resonance range of a system
¯ All specifications of the corresponding enclosed documentation must be
observed.
This is vital for a safe and trouble−free operation and for achieving the specified
product features.

4.1 Important notes
¯ Use load carrying equipment for transport!
¯ Before the transport
Mechanical installation
Important notes
– check that all components are safely mounted,
– fasten all transport aids (eye bolts or support plates).
Danger!
Danger due to toppling or falling loads!
¯ The payload of the hoists and load handling devices must at least
correspond to the weight of the load.
¯ The load must be secured in such a way that it cannot topple or fall
down.
¯ Do not stay under a pending load!
EN
4.2 Transport equipment for gearbox
Danger!
The motors attached to the gearbox are partially equipped with eyebolts.
These are exclusively determined for mounting/dismounting the motor
to the gearbox and must not be used for the complete geared motor!
Please see the position of the transport threads in the following figures. Gearboxes from
size H210 are in series equipped with a transport thread for eye bolts according to DIN
580 in the gearbox cover. In case of smaller drives, the thread in the output shaft can be
used. The eye bolt is not included in the scope of supply!

Tab. 2 Load carrying capacity of eye bolt in kg
Danger!
Completely screw in transport aids (such as eye bolts or bearing plates),
they must be flat and applied over their entire surface!
If possible, the transport aids (such as eye bolts or bearing plates) must
be stressed vertically in the direction of the screw axis! Angular tension or
tension to the sides reduces the payload! Observe the information
provided in the DIN 580!
Use additional appropriate lifting aids, if required, to achieve a direction
of loading which is as vertical as possible (highest payload). Secure lifting
aids against shifting!
Stop!
Observe load carrying capacity!
Staying under floating load is prohibited!
EN
4.3 Preparation
Note!
Thoroughly remove anticorrosion agents from output shafts and flange
faces.
4.3.1 General information about the assembly of drive systems
Stop!
The lubricant fill quantity of the gearboxes is matched to the mounting
position. The mounting position indicated on the nameplate must be
observed to avoid damage to the gearbox.

4.3.2 Gearboxes with breathers
Mechanical installation
Preparation
Gearboxes with breathers
Stop!
Do not place gearbox onto breather valve!
No ventilation measures are required for the gearboxes H45, H100 and H140.
Gearboxes which are delivered with a ventilation unit are equipped with a label on the
gearbox.
Remove the transport locking device on the vent valve before the first commissioning.
EN
Note!
Loosely enclosed vent valves must be mounted in accordance with the
4.3.3 Condensation drain hole of the motor
mounting position, ( 23).
Note!
Lenze delivers motors with condensation drain holes with sealed
condensation drain holes. The holes are sealed with a plastic plug or a
locking screw. This does not affect the type of protection and the motor is
protected against the ingress of foreign substances during transport and
operation. Further information, ( 28).

Coupling hubs
Note!
Standard hubs, clamping hubs and clamping ring hubs are
maintenance−free.We recommend checking the star−shaped spider and
system components when inspecting the drive.
Mounting the standard hub / clamping hub
1. Fit motor key (2).
– Fit enclosed key for drive sizes C, E, F.
2. Push the coupling hub over the motor shaft, mounting dimension m (see Fig. 2
and Tab. 3) must be observed.
EN
3. Secure coupling hub against axial movement using the fixing screw or clamping
screw (1).
4. Lay spider in the coupling claw on the gearbox side.
5. Align claws of the motor−side coupling hub with its counterpart.
6. Slowly push on motor, and bolt on to the gearbox flange.

1. Grease the contact surfaces of the motor shaft using a thin−bodied oil, e. g.
Castrol 4 in 1" or Klüber Quitsch Ex"!
Stop!
Do not use oil or grease with molybdenum−disulphide or high−pressure
additives, or grease pastes!
2. Push the coupling hub over the motor shaft, mounting dimension m" (see Fig. 2
and Tab. 3) must be observed.
3. Align the hub and tighten the clamping screws until they have contact.
4. Tighten the clamping screws evenly and crosswise with gradually rising torque
until the indicated tightening torque (see Tab. 3) is reached at all clamping screws.
In the intermediate steps, this procedure should also be repeated until the
indicated tightening torque is reached at all clamping screws.
5. Lay spider in the coupling claw on the gearbox side.
6. Align claws of the motor−side coupling hub with its counterpart.
7. Slowly push on motor, and bolt on to the gearbox flange.

Stop!
Each screw must only be loosened by half a revolution per pass! Unscrew
all clamping screws by 3 − 4 threads.
2. Remove the screws next to the forcing threads and screw them into the other
threads until they have contact.
3. Tighten the screws in the forcing threads crosswise and step−by−step so that the
clamping ring is loosened.
4. Clean and grease all contact surfaces including threads and head of the clamping
screws before reassembly.

Note!
¯ Gearboxes below 200 Nm are lubricated for life.
¯ The mechanical power transmission system is maintenance−free.
7.2 Maintenance intervals
¯ In case of gearboxes > 200 Nm, the lubricant must regularly be replaced.
– The type of lubricant is indicated on the nameplate. Replace the lubricant only
with the same type of lubricant.
– The lubricant maintenance interval depends on the lubricant temperature, see
Fig. 4.

Drain condensation
Depending on the mounting position, the condensation drain holes are always at the
bottom of the motor!

Maintenance
Repair
Motors
– the motor must be deenergised;
– the plugs (screws) must be removed.
Stop!
To restore the enclosure, re−insert the plugs (screws) after condensate
drainage. If the condensation drain holes are not sealed again, the IP
enclosure of the motor will be reduced. For horinzontal motor shafts to
IP23 and for vertical motor shafts to IP20.

¯ Correct screw tightening torque has not
been reached
– Insufficient number of passes, not all
screws are tightened correctly.
¯ Machine shaft and hollow shaft bore
not sufficiently degreased
¯ Wrong component part dimensions
– Fits, roughnesses
¯ Yield point of machine shaft material is
too low
– Re > 300 N/mm2 required
¯ Friction factors are too low
– Coefficients of friction m ³ 0.15
required
¯ The shrink disc itself has been
degreased so that the screws and the
bevels are dry. Due to incorrect friction
factors, the shrink disc cannot be
tightened correctly.
