Lenze ¯ MA 12.0017 ¯ 3.0
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

8 Lenze ¯ MA 12.0017 ¯ 3.0
2.2 Application as directed
Low−voltage machines are not household appliances, but are intended as components
that are only applied for re−use for industrial or professional purposes in terms of
IEC/EN 61000−3−2.
They meet the requirements of the Low−Voltage Directive 2006/95/EC and the
harmonised standards of the IEC/EN60034 series.
It is permissible to use low−voltage machines with IP23 protection or less outdoors only
if special protective measures are taken.
Do not use the integrated brakes as fail−safe brakes. It cannot be ruled out that the
braking torque will be reduced due to disruptive factors that 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 EC 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
Note!
Increased surface and corrosion protection can be achieved by using
adapted coating systems.

Lenze ¯ MA 12.0017 ¯ 3.0
2.4 Residual hazards
Protection of persons
¯ Risk of burns!
–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.

4.1 Important notes
Before transport
¯ Make sure that all components are securely mounted;
¯ Make sure that all components with a loose fastening are secured or removed;
¯ Tighten all transport aids (eye bolts or support plates).
Use lifting devices for the transport! (15)
Stop!
Danger by tipping or falling loads!
Observe carrying capacities!
¯ The carrying capacity of the hoists and load handling devices must be
at least the weight of the load, weights (14).
¯ Secure the load to prevent it from tipping over or falling down.
¯ Standing beneath suspended loads is prohibited!
Risk of breakage!
The motors mounted to the gearbox are partly equipped with transport
eyebolts that are solely intended for mounting/dismounting the motor
to/from the gearbox and that must not be used for transport of the
geared motor!
4.2 Transport equipment for gearboxes
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!
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 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!
Standing beneath floating loads is prohibited!

Stop!
Shocks and impacts on the shaft damage the roller bearings.
¯ Draw the transmission elements onto the output shaft only by using the
centering thread.
¯ Align the gearbox shaft and transmission elements in an accurate fashion in order
to prevent tensioning.
¯ Mount belt pulleys, sprockets, or gear wheels as closely as possible to the gearbox
in order to keep the bending load of the shaft and the bearing forces at a
minimum level.
4.4.3 Mounting of g500 short/servo adapters with clamping connection
Important notes
¯ The transmission is made in a force−fitting manner via a clamping connection.
Greases, oils and other substances which reduce the friction factor reduce the
torque to be transmitted which is why these should be avoided in the connection.
¯ The motor shaft diameter must be designed with fit k6.
¯ The motor centering diameter must be designed with fit j6.
¯ With regard to smooth running tolerance of the motor shaft, concentricity of the
centering and axial runout of the mounting flange, the motor must fulfil the
requirements according to DIN 42955 R (reference values for smooth running
< 0.025 mm; axial runout and concentricity < 0.05 mm).

If the motor shaft is provided with a keyway, align the motor shaft in
such a way that the keyway is located opposite to the terminal screw.
Note!
Lenze recommends the use of smooth motor shafts without slots!
5. Position the motor shaft vertically and centrically to the hollow drive shaft and
insert it carefully into the hollow drive shaft. Exert only little force in order to
prevent damage to the ball bearing in the bell housing and the motor. Never
assemble the parts by applying blows! If it is difficult to put the parts together,
check if the terminal screw (8) has not been tightened too much. If required,
loosen it.
6. Only when the flange of bell housing (2) and motor (3) lie flat on top of each
other, the fixing screws may be mounted for the motor (screw strength at least
8.8, tightening torques according to strength 8.8). Secure the screw connections
with medium−strength screw locking adhesive.
7. Tighten terminal screw (8). Tightening torque according to table ±10%.
