Safety instructions
General safety instructions for drive components
Temperatures
The permissible temperature range is determined by the following:
• The lubricant specifications in connection with the expected oil temperatures in
operation (see chapter 8.1 and nameplate).
• The thermal class of the motor considering the motor temperature expected
during operation (see nameplate and/or Operating Instructions of the motor).
The operating temperature is determined by the power loss, the ambient temperature
and the cooling system!

Stop!

Danger!
With mineral oil, the upper temperature limit for continuous operation is
80°C, with synthetic oil and shaft sealing rings made of FP (Viton) 100°C.
If these temperatures are exceeded, measures are necessary to reduce
the temperature, see chapter 9.
Depending on the operating conditions, surfaces may be hot, provide
protection against accidental contact.
Ambient media
• Gearboxes are protected against dust and spray water.
• Motors according to their enclosure (see nameplate and/or Operating Instructions
for the motor).
• Ambient media - especially chemically aggressive - can destroy shaft seals and
coatings (plastic). Abrasive media endanger shaft seals.
• The installation site of the drive must be free of shocks and vibration.
• Dirt of dust deposits impede the heat dissipation (cooling).
Transport, storage
• Transport and storage in a dry, low-vibration environment without aggressive
atmosphere; preferably in the packaging provided by the manufacturer.
– Protect against dust and impacts.
– Observe climatic conditions according to the technical data.
• Use load carrying equipment for transport! ( 25)
Before transport
• check that all component parts are safely mounted;
• check that all component parts with a loose fastening are secured or removed;
• tighten all transport aids (eye bolts or support plates).
Use an appropriate means of transport and lifting equipment! ( 25)

General safety instructions for drive components
If you do not install the motor immediately, ensure proper storage conditions.
• Up to one year:
– Shafts and uncoated surfaces are delivered in a protected against rust status.
Aftertreatment is required where the corrosion protection has been damaged.
– Remove the plug for motors with condensation drain holes (special version).
• More than one year, up to two years:
– Apply a long-term corrosion preventive (e.g. Anticorit BW 366 from the Fuchs
company) to the shafts and uncoated surfaces before storing the motor away.
Corrosion protection
Lenze offers paints with different resistance characteristics for drive systems. Since the
resistance may be reduced when the paint coat is damaged, defects in paint work (e.g.
through transport or assembly) must be removed professionally to reach the required
corrosion resistance.
Mechanical installation
• Provide for careful handling and avoid mechanical overload. During handling
neither bend components, nor change the insulation distances.
Electrical installation
• Carry out the electrical installation according to the relevant regulations (e. g.
cable cross-sections, fusing, connection to the PE conductor). Additional notes are
included in the documentation.
• The Instructions contain notes concerning wiring according to EMC regulations
(shielding, earthing, filters and cable routing). The compliance with limit values
required by the EMC legislation is the responsibility of the manufacturer of the
machine or system.
Warning: The inverters are automation components which can be used in industrial
environment according to EN 61000-6-4. These products may cause radio
interference in residential areas. If this happens, the operator may need to take
appropriate action.
• Only plug in or remove pluggable terminals in the deenergised state!
Commissioning
• If required, you have to equip the system with additional monitoring and
protective devices in accordance with the respective valid safety regulations (e. g.
law on technical equipment, regulations for the prevention of accidents).
• Before commissioning remove transport locking devices and keep them for later
transports.

Safety instructions
Application as directed
Geared motors for deep-freeze applications
• Geared motors for deep-freeze applications are specially optimised to operation
at very low temperatures. Observe that for operation outside the temperature
range specified (e.g. during commissioning) increased wear or even failures may
occur.
• We recommend loading the gearbox with a maximum of 50 % of the rated output
torque if it is outside the specified temperature range during commissioning.
2.2
Application as directed
All products which this documentation applies to are no household appliances but are
exclusively intended as components for re-utilisation for commercial use or
professional use in terms of IEC/EN 61000-3-2. They meet the requirements of the
Low-Voltage Directive 2006/95/EC and the requirements of the harmonised standards
of the IEC/EN 60034 series.
Only use the products under the operating conditions and power limits specified in this
documentation.
Do not use the brakes installed as fail-safe brakes. It cannot be ruled out that the braking
torque is reduced by disruptive factors which cannot be influenced.
• Drives
– ... must only be operated under the operating conditions and power limits
specified in this documentation.
– ... comply with the protection requirements of the EU Low-Voltage Directive.
Any other use shall be deemed inappropriate!
2.3
Foreseeable misuse
• Do not operate the motors
– ... in explosion-protected areas
– ... in aggressive environments (acid, gas, vapour, dust, oil)
– ... in water
– ... in radiation environments


Residual hazards
2.4
Residual hazards
Protection of persons
• Risk of burnst!
– Hot surfaces up to 140 °C during operation! Provide protection against contact.
• High-frequency voltages can be capacitively transferred to the motor housing
through the inverter supply.
– Earth motor housing carefully.
• Risk of injury due to rotating shaft!
– Before working on the motor ensure that the motor is at standstill.
• Danger of unintentional starting or electrical shocks!
– Connections must only be made when the equipment is deenergised and the
motor is at standstill.
– Installed brakes are no fail-safe brakes.
• Dangerous voltages at the power terminals, even if the plug is removed: residual
voltage >60 V!
Motor protection
• Installed thermal detectors do not offer full protection to the machine.
– If required, limit the maximum current, parameterise the inverter so that it will
be switched off after some seconds of operation with I > IN, especially if there is
the danger of blocking.
– Installed overload protection does not prevent an overload under any
conditions.
• Installed brakes are no fail-safe brakes.
– The torque can be reduced due to disruptive factors that cannot be influenced,
e.g. by ingressing oil due to a defect shaft sealing ring on the A side.
• Fuses are no motor protection.
– Use current-dependent motor protection switches at an average operating
frequency.
– Use installed thermal detectors at a high operating frequency.
• Excessive torques lead to a break of the motor shaft or demagnetisation.
– The maximum torques according to catalogue must not be exceeded.
• Lateral forces from the motor shaft may occur.
– Align shafts of motor and driving machine exactly to each other.
• If deviations from normal operation occur, e.g. increased temperature, noise,
vibration, determine the cause and, if necessary, contact the manufacturer. If in
doubt, switch off the motor.
• Design with plug:
– Never disconnect plug when energised! Otherwise, the plug can be destroyed.
– Switch off power supply and inhibit controller prior to disconnecting the plug.

Storage
5.2
Storage
If you do not install the gearbox immediately, provide for proper storage conditions.
• Generally
– Store gearboxes indoors in a dry, clean (low-dust) and sunlight-protected
environment.
– The storage location must be free from vibrations and shocks (Veff < 0.2 mm/s)
in order to prevent roller bearing standstill damage.
– Temperature changes with condensate formation are to be avoided.
– Do not activate ventilation unit, in order to prevent air exchange with the
ambient air.
• Up to one year:
– Store gearboxes with a ventilation unit with the vent plug on top.
– Shafts and uncoated surfaces are delivered in a protected against rust status.
Aftertreatment is required where the corrosion protection has been damaged.
– Remove the plug for motors with condensation drain holes (option)( 28).
• More than one year, up to two years:
– Apply a long-term corrosion preventive (e.g. Anticorit BW 366 from the Fuchs
company) to the shafts and uncoated surfaces before storing the motor away.
– Install gearbox in mounting position A.
– Fill gearbox up to the top vent hole / oil hole with the oil grade specified (see
nameplate). Then mount the locking screw and ventilation unit (do not activate)
again.

Note!
Thoroughly remove anticorrosion agents from output shafts and flange
faces.
Correcting the oil quantity
If the amount of oil in the gearbox has been increased for the purpose of longtime
storage (see chapter 5.2), the oil must be drained completely and then refilled for the
mounting position provided. The following steps have to be observed:
1. Place receptacle under oil drain plug.
2. Remove breathing / oil filler plug.
3. Completely drain lubricant.
4. Screw in oil drain plug.
5. Fill in amount of oil for the mounting position provided (according to nameplate).
6. Screw in breathing / oil filler plug.

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, ( 57).
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.
• Take safety measures prior to any operation:
– Disconnect the machine from the mains, ensure standstill of the drive system
and avoid any machine movement.
– Check faultless state of the drive system. Never install and commission
damaged drive systems.
– Check drive function - machine function assignment. Check direction of
( 28)rotation.
• The mounting surfaces must be plane, torsionally rigid and free from vibrations.
• Align drive system on mounting surfaces exactly with the machine shaft to be
driven.
– Be sure to carry out mounting in a manner free from distortion, in order to avoid
additional loads.
– Even out slight inaccuracies by the use of suitable flexible couplings.
• Support reaction torque by suitable measures.
• Be absolutely sure to secure fastenings of accessories and built-on accessories so
that they won’t come loose.
We recommend glueing screwed connections.
5.3.3
Assembly of transmission elements on solid shafts
Draw the transmission elements onto the output shaft only by using the centering
thread.

Danger!
Loose drive components or drive components falling down may cause
injury to persons or damage to the machine. Secure the drive
components before disassembly.
1. Remove protective cap (1).
2. Loosen clamping screws (2) evenly one after the other each by ¼ revolution in
several passes. Do not unscrew clamping screws completely to prevent accidents!
3. Press off outer ring (see Fig. 9), if necessary. For this, loosen the outer ring using
the forcing threads and some clamping screws (number corresponding to the
forcing threads in the inner ring). For loosening the outer ring, screw in the screws
evenly to prevent canting. Press off the outer ring until loosened completely.
4. Remove the drive from the machine shaft.

Stop!
Dismantle the shrink disc only for cleaning purposes. Afterwards, grease
bevel surfaces and screws using a solid lubricant with a friction factor of
 = 0.04.
• Suitable lubricants on molybdenum-disulphide lubricant (MoS2) basis are, e.g.:
– Molykote G Rapid (company Dow Corning)
– Molykote BR2 Plus (company Dow Corning)
– Molykombin UMFT1 (company Klüber Lubrication)
Usually, disassembly problems only occur if:
• the connection is spinning due to overload or a too low friction factor and fretting
corrosion has occurred,
• the shrink disc has been tightened too much leading to a plastic deformation of
components,
• the components are corroded.

Gearboxes with breathers
Stop!
Do not place gearbox onto breather valve!
For gearboxes of sizes 03, 04 and 05 (exception GSS 05), no ventilation measures are
required.
For gearboxes of sizes 06 to 14 and GSS 05, ventilation units are mounted. However, in
specific cases they may be dispensed with. For gearbox sizes 09 to 14 in mounting
position C we recommend using an oil compensation reservoir ( 52).
Gearboxes that are delivered with a ventilation unit are provided with a label.
Remove transport locking device on the vent valve.
GT-GNG-13285760.iso/dms
If it deviates from standard mounting positions A - F, the ventilation unit must be
checked with regard to its function. Mount ventilation units that are loosely attached
(deviating from the standard) as specified in chapter 5.3.11. Gearboxes that are suitable
for several mounting positions ( 68) are delivered without ventilation units.
Ensure ventilation before initial commissioning!

Maintenance
When they are delivered, Lenze gearboxes and geared motors are filled with a drive and
type-specific lubricant so that they are ready for production. This initial filling
corresponds to a lubricant from the column of the respective Lenze gearbox type. When
the order is placed, the mounting position and the design are the decisive factors for the
lubricant amount.

Note!
Gearboxes of sizes 03 and 04 are lubricated for life. Due to the low
thermal load, no lubricant change is required.
8.1
Maintenance intervals
• The mechanical power transmission system is free of maintenance.
• Gearboxes as of size 05 (pre-stages as of size 06) require regular lubricant
replacement.
– The type of lubricant is indicated on the nameplate. Replace the lubricant only
with the same type.
– The lubricant maintenance interval depends on the oil temperature, see Fig. 13.
• Shaft seals and roller bearings:
– The service life depends on the operating conditions.
– Replace seals in case of leakage to avoid consequential damage.

Note!

Stop!
When changing the lubricant, Lenze recommends also changing the
grease packing of the bearings and replacing the rotary shaft seals!
For drive systems: Also observe the maintenance intervals for the other
drive components!

Opening the condensation drain hole
Depending on the mounting position, the condensation drain holes are always at the
bottom of the motor!
• For condensate drainage
– the motor must be deenergised;
– the plugs (screws) must be removed.

Fig. 14
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.

8.2.6
Lubricant amounts for combinable mounting positions
For the gearbox sizes 03 ...05 a combination of different mounting positions with
amounts of lubricant to suit are permissible as per the following tables.
Advantage:
Easier logistics for users who use gearboxes in different mounting positions.
Disadvantage:
On some gearboxes more lubricant is necessary in the gearbox than is necessary
technically. As a result a higher internal pressure is produced.
