Lenze ¯ MA 12.0013 ¯ 3.0
Temperatures
The permissible temperature range is determined by the following:
¯ The lubricant specifications in connection with the expected oil temperatures in
operation (see chapter 7.2 and nameplate).
¯ The thermal class of the motor considering the motor temperature expected
during operation (see nameplate and/or operating instructions of the motor).
¯ Protect geared motors against direct solar radiation. Avoid heat concentration
beneath covers.
The operating temperature is determined by the power loss, the ambient temperature
and the cooling system!
Stop!
With mineral oil, the upper temperature limit for continuous operation is
80°C, with synthetic oil and shaft sealing rings made of FP (Viton) it is
100°C. If these temperatures are exceeded, measures are necessary to
reduce the temperature, (57).
Danger!
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.
¯ Protect geared motors against direct solar radiation. Avoid heat concentration
beneath covers.
¯ Dirt of dust deposits impede the heat dissipation (cooling).
Transport
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! (19)

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)(20).
¯ 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.
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.
Note!
Increased surface and corrosion protection can be achieved by using
adapted coating systems.
Mechanical installation
¯ Provide for careful handling and avoid mechanical overload. During handling
neither bend components, nor change the insulation distances.

Lenze ¯ MA 12.0013 ¯ 3.0
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.
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.
Disposal
Sort individual parts according to their properties. Dispose of them as specified by the
current national regulations.

Lenze ¯ MA 12.0013 ¯ 3.0
Motor protection
¯ Installed thermal detectors are no full protection for the machine.
–If required, limit the maximum current, parameterise the controller such 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 average operating
frequency.
–Use installed thermal detectors at high operating frequency.
¯ In the case of permanent−magnet motors, too high torques cause
demagnetisation.
–The maximum torques according to catalogue must not be exceeded.
¯ 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.
Fire protection
¯ Fire hazard
–Prevent contact with flammable substances.

4.1 Important notes
¯ Use load carrying equipment for transport!
¯ Before the transport
–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.
¯ Secure the load handling device so that it won’t slip from its position.
¯ The load must be secured in such a way that it cannot topple or fall
down.
¯ Do not stay under a pending load!
4.2 Transport
Danger!
The motors attached to the gearbox are partially equipped with eyebolts.
They are exclusively determined for mounting/dismounting the motor to
the gearbox and must not be used for the complete geared motor!
Fig. 1 Ear for transporting the complete drive system
Stop!
Observe load carrying capacity!
Standing beneath floating loads is prohibited!

4.3 Preparation
¯ Protect shaft sealing rings against contact with solvents!
¯ Thoroughly remove anticorrosion agents from the output shaft and from flange
faces.
¯ Repair paintwork damage.
¯ In some cases, due to lack of space, stud bolts with nuts must be used instead of
head screws. In these cases, contact Lenze, if necessary.
Tighten all screw connections with the torques given and lock them with standard
screw locking adhesive!

gaskets.
Correcting the lubricant amount
If the oil quantity in the gearbox has been increased for longtime storage ((10)), the
oil must be drained completely and then must be refilled for the mounting position
provided. The following steps must be complied with:
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 ventilation / oil filler plug.
Condensation drain hole
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, (56).
