2 Safety instructions
2.1 General safety instructions for drive components
(in accordance with Low−Voltage Directive 2006/95/EC)
At the time of dispatch, the drive components are in line with the latest state of the art and
can be regarded as operationally safe.
Scope
The following safety instructions generally apply to Lenze drive components.
The product−specific safety and application notes given in this documentation must be
observed!
General hazards
}Danger!
Disregarding the following basic safety measures may lead to severe personal
injury and damage to material assets!
ƒLenze drive components ...
... must only be applied as directed.
... must never be commissioned if visibly damaged.
... must never be technically modified.
... must never be commissioned if incompletely mounted.
... must never be operated without the required covers.
ƒAll specifications of the corresponding enclosed documentation must be observed.
This is vital for a safe and trouble−free operation as well as for achieving the specified
product features.
ƒOnly qualified, skilled personnel is permitted to work on and with Lenze drive
components.
According to IEC 60364 / CENELEC HD 384, these are persons who ...
... are familiar with the installation, mounting, commissioning, and operation of the
product.
... have the qualifications required for their occupation.
... know and are able to apply all national regulations for the preventions of accidents,
directives and laws applicable on site.

BA 13.0011−EN 1.0
Transport, storage
ƒTransport and storage in a dry, low−vibration environment without aggressive
atmosphere; preferably in the packaging provided by the manufacturer.
– Protect against dust and shocks.
– Comply with climatic conditions according to the technical data.
ƒBefore transport
– Check that all transport locking devices are mounted.
– Tighten all transport aids.
)Note!
Do not apply extra loads to the product as the transport aids (such as eye bolts
or bearing plates) are designed for the weight of the motor only (refer to the
catalogue for the weight).
Mechanical installation
ƒInstall the product according to the regulations of the corresponding
documentation. In particular observe the section "Operating conditions" in the
chapter "Technical data".
ƒProvide for a careful handling and avoid mechanical overload. During handling
neither bend components, nor change the insulation distances.
Electrical installation
ƒCarry 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.
ƒThe documentation contains notes for the EMC−compliant installation (shielding,
earthing, arrangement of filters and installation of the cables). The manufacturer of
the system or machine is responsible for the compliance with the limit values
required in connection with EMC legislation.
ƒFor compliance with the limit values for radio interference emission at the site of
installation, the components − if specified in the technical data − have to be mounted
in housings (e. g. control cabinets). The housings have to enable an EMC−compliant
installation. In particular observe that for example control cabinet doors preferably
have a circumferential metallic connection to the housing. Reduce openings or
cutouts through the housing to a minimum.
ƒOnly plug in or remove pluggable terminals in the deenergised state!
Commissioning
ƒIf 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).
ƒBefore commissioning remove transport locking devices and keep them for later
transports.

Safety instructions
Application as directed

10 BA 13.0011−EN 1.0
2.2 Application as directed
Low−voltage machines are no household appliances, they are designed as components for
industrial or professional use in terms of IEC/EN 61000−3−2 only.
They comply with the harmonised standards of the series IEC/EN60034.
Low−voltage machines are components for installation into machines as defined in the
Machinery Directive 2006/42/EC. Commissioning is prohibited until the conformity of the
end product with this directive has been established (follow i. a. IEC/EN 60204−1).
It is only permissible to use low−voltage machines with IP23 protection or less outdoors if
special protective measures are taken.
The integrated brakes must not be used as safety brakes. It cannot be ruled out that
interference factors which cannot be influenced cause a brake torque reduction.
ƒDrives
– ... 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 Improper use
ƒDo not operate the motors
– ... in explosion−protected areas
– ... in aggressive environments (acid, gas, vapour, dust, oil)
– ... in water
– ... in radiation environments

BA 13.0011−EN 1.0
2.4 Residual hazards
Protection of persons
ƒDo not use the integrated brakes as fail−safe brakes. It cannot be ruled out that
certain disruptive factors that cannot be influenced such as oil ingress due to a
defective shaft sealing ring at the drive end may reduce the braking torque.
Motor protection
ƒIntegrated temperature sensors do not provide full protection for the machine. If
necessary, limit the maximum current. Parameterise the controller so that the
motor will be switched off with I > Irafter a few seconds of operation, especially if
there is a risk of blocking.
ƒIf 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 low−voltage machine.
ƒOverload protection does not protect against overloading under all conditions.

4.4 Rated data
ƒThe most important rated data of the motor are indicated on the nameplate.
– Further technical data can be obtained from the catalogues.
ƒThe indicated torques and weights are guide values for the selection of the
transmission elements and foundations.
ƒThe rated data indicated on the nameplate refer to operation with Lenze servo
inverters of the 9300 and 9400 series at an inverter input voltage (mains voltage) of
400 V.
)Note!
ƒThe motors can also be connected to inverters others than servo inverters of
the 9300 and 9400 series:
– Depending on the modulation and control performance of the inverter it
might be necessary to derate the power if excessive temperatures are
detected (see Tab. 1).
