Application as directed
ƒLenze drive systems
– are intended for use in machinery and plant,
– must only be used for the purposes ordered and confirmed,
– must only be operated under the ambient conditions prescribed in these
Operating Instructions,
– must not be operated beyond their corresponding power limits.
Any other use shall be deemed inappropriate!
1.5 Legal regulations
Liability
ƒThe information, data, and notes in the Operating Instructions were state of the art
at the time of printing. Claims referring to drive systems which have already been
supplied cannot be derived from the information, illustrations, and descriptions.
ƒWe do not accept any liability for damage and operating interference caused by:
– inappropriate use,
– unauthorised modifications to the drive system,
– improper working on and with the drive system,
– operating faults,
– disregarding the Operating Instructions.
Warranty
ƒConditions of warranty: see terms of sale and delivery of Lenze Drive Systems

2 Safety instructions
2.1 Personnel responsible for safety
Operator
ƒAn operator is any natural or legal person who uses the drive system or on behalf of
whom the drive system is used.
ƒThe operator or his safety officer must ensure
– that all relevant regulations, instructions and legislation are observed.
– that only qualified personnel work with and on the drive system.
– that the personnel have the Operating Instructions available for all corresponding
operations.
– that non−qualified personnel are prohibited from working with and on the drive
system.
Skilled personnel
Skilled personnel are persons who − because of their education, experience, instructions,
and knowledge about corresponding standards and regulations, rules for the prevention
of accidents, and operating conditions − are authorised by the person responsible for the
safety of the plant to perform the required actions and who are able to recognise potential
hazards.
(See IEC 364, definition of skilled personnel)
2.2 General safety information
ƒThis safety information does not claimed to be complete. In case of questions and
problems, please contact your Lenze representative.
ƒAt the time of delivery the drive system meets the state of the art and ensures safe
basic operation.
ƒThe drive system is a source of danger for persons, for the drive system itself, and for
other material assets of the operator, if
– unqualified personnel works with and on the drive system,
– the drive system is used inappropriately.
ƒThe drive systems must be designed such that they perform their functions after
proper installation and with application as directed in fault−free operation and that
they do not cause hazards for persons. This also applies for their interaction with the
complete plant.
ƒBe sure to take appropriate measures in the case of drive system failure so that no
material damage occurs.
ƒOperate the drive system only when it is in a proper state.
ƒRetrofittings, modifications, or redesigns of the drive system are basically
prohibited. Lenze must be contacted in all cases.

Danger!
Only transport the drive with transport equipment or hoists which are suitable
for this load. Ensure a safe fixing. Avoid shocks!
4.1 Storage
If you do not install the gearbox immediately, ensure appropriate conditions of storage.
ƒUp to one year:
– Without special measures in dry, dust−free rooms which are protected against
sunlight.
– Store the gearbox with ventilation such that the breather screw is located at the
top.
– Shafts and bright surfaces are delivered with protection against corrosion.
ƒMore than one year:
– Please contact Lenze.
4.2 Mounting

4.2.2 General information about the assembly of drive systems
ƒTake safety measures prior to any operation:
– Disconnect the machine from the mains, ensure standstill of the machine and
avoid any machine movement.
– Check the proper state of the drive system. Never install and set up damaged drive
systems.
– Check the combination of drive function and machine functions. Check the
direction of rotation.
ƒThe mounting surfaces must be even, without torsion, and free from vibration.
ƒAlign the drive system on the mounting surfaces exactly with the machine shaft to
be driven.
– Ensure that the assembly is without torsion, to avoid additional load.
– Compensate for minor misalignments by using suitable flexible couplings.
ƒSupport the reaction torque appropriately.
ƒFixings of accessories and attachments must be secured against loosening. We
recommend that screw connections are glued.
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.
4.2.3 Assembly of transmission elements on solid shafts
ƒDraw the transmission elements onto the output shaft only by using the centering
thread.
Stop!
Shocks and blows to the shafts damage the roller bearings.

4.2.5 Mounting of gearboxes with hollow shaft with keyway
1. Draw the gearbox with hollow shaft onto the machine shaft to be driven:
– Use a suitable assembly paste.
– Take up forces only via the hollow shaft, and not via gearbox housing.
2. Secure the gearbox axially:
– The hollow shaft is equipped with snap ring grooves for axial securing (fig. 3). Parts
required for fixing the shaft are not included in the scope of supply.

4.2.6 Breather screw
ƒIf your gearbox is equipped with a breather screw, the screw is marked by a label.
Stop!
Before the first set−up, remove the plug from the breather screw. Without
ventilation, the seals may be damaged because of the rising pressure during
operation.

6 Commissioning and operation
Stop!
The drive may only be commissioned by skilled personnel!
6.1 Before switching on
Check:
ƒDoes the drive appear undamaged?
ƒIs the mechanical fixing o.k.?
ƒHas the electrical connection been carried out properly?
ƒAre all rotating parts and surfaces that may become hot protected against contact?
ƒIf the oil level of the drive has been increased due to storage purposes (see
chapter 4.1), it must be reduced again to the height permissible for the intended
mounting position.
ƒFor gearboxes with breathing:
– Has the transport locking device been removed?
6.2 During operation
During operation, check the drive periodically and take special care of:
ƒDeviations from normal operation such as
– abnormal noises, stronger vibrations, or increased temperatures
– leakages,
– loose fixing elements,
– the condition of the electrical cables.
ƒIf any interference should occur, you have to stop the drive and go through the steps
for troubleshooting and fault elimination (chapter 8). If the interference cannot be
eliminated, please contact the Lenze Service.

7 Maintenance
7.1 Maintenance intervals
ƒThe mechanical power transmission system is free of maintenance.
ƒShaft seals and roller bearings:
– The service life depends on the operating conditions.
– Replace seals in case of leakage to avoid consequential damage.
ƒLubricants are subject to natural aging and must be replaced at regular intervals:
– The type of lubricant is indicated on the nameplate. If not indicated, please see
"List of lubricants" (Tab. 2).
– Only use similar lubricants when changing the lubricant.
– For maintenance intervals: see Tab. 2 "List of lubricants".
Stop!
Also observe the maintenance intervals for the other drive components!
