Residual hazards
Even if notes given are taken into consideraon and protecve measures are implemented,
the occurrence of residual risks cannot be fully prevented.
The user must take the residual hazards menoned into consideraon in the risk assessment
for his/her machine/system.
If the above is disregarded, this can lead to severe injuries to persons and damage to
property!
Product
Observe the warning labels on the product!
Dangerous electrical voltage:
Before working on the product, make sure there is no voltage applied to the power terminals!
Aer mains disconnecon, the power terminals will sll carry the hazardous electrical voltage
for the me given next to the symbol!
High leakage current:
Carry out xed installaon and PE connecon in compliance with:
EN 61800‑5‑1 / EN 60204‑1
Hot surface:
Use personal protecve equipment or wait unl the device has cooled down!
Protecon of persons
•The power terminals may carry voltage in the switched-o state or when the motor is
stopped.
-Before working, check whether all power terminals are deenergized.
•Voltages may occur on the drive components (e.g. capacive, caused by inverter supply).
-Careful earthing in the marked posions of the components must be carried out.
•There is a risk of burns from hot surfaces.
-Provide protecon against accidental contact.
-Use personal protecve equipment or wait unl the device has cooled down.
-Prevent contact with ammable substances.
•There is a risk of injury due to rotang parts.
-Before working on the drive system, ensure that the motor is at a standsll.
•There is a risk of accidental start-up or electric shock.
Motor protecon
•Installed temperature sensors are no full protecon for the machine.
-If necessary, limit the maximum current. Parameterize the inverter so that it will be
switched o aer some seconds of operaon with I > Irated , especially if there is a risk
of blocking.
-Integrated overload protecon does not prevent overloading under all condions.
•The fuses are no motor protecon.
-Use a current-dependent motor protecon switch.
-Use the built-in temperature sensors.
•Too high torques cause a fracon of the motor sha.
-Do not exceed the maximum torques according to the technical data on the
nameplate.
•Lateral forces on the motor sha are possible.
-Align the shas of motor and driven machine exactly to each other.

•The technical data and the data regarding the supply condions can be found on the
nameplate and in this documentaon.
•Ambient media − especially chemically aggressive ones − may damage sha sealing rings,
lacquers and plascs.
•Lenze oers special surface and corrosion protecon in this case.
Preparaon
•Protect sha sealing rings from contact with solvents.
•Remove protecon covers from shas.
•Thoroughly remove ancorrosion agents from the sha and from ange faces.
•Draw the transmission elements onto the output sha only by using the centering thread.
•Align the output sha and transmission elements exactly to avoid tensions.
•Mount belt pulleys, sprockets, or gear wheels as close as possible to the sha shoulder in
order to keep the bending load of the sha and the bearing forces at a minimum level.
•Tighten all screw connecons with the specied torques and secure them with standard
screw locking adhesive.
•Check paint for damage and repair professionally.
Installaon
•The mounng surfaces must be plane, torsionally rigid and free from vibraons.
•The mounng areas must be suited to absorb the forces and torques generated during
operaon.
•Ensure an unhindered venlaon.
•For versions with a fan, keep a minimum distance of 10 % from the outside diameter of the
fan cover in intake direcon.

Mounng
Transmission elements
•Fit or remove transmission elements only using suitable equipment.
•For ng the transmission elements use the center hole in the sha.
•Avoid impacts and shocks.
•In case of a belt drive, tension the belt in a controlled manner according to manufacturer
informaon.
•Be sure to carry out mounng in a manner free from distoron.
•Compensate minor inaccuracies by suitable exible couplings.
Fastening
•Use screws with a minimum property class of 8.8.
•Observe prescribed ghtening torques.
•Secure against unintended loosening.
•For alternang loads, we recommend applying anaerobic curing adhesive between ange
and mounng surface.

Important notes
DANGER!
Risk of injury and risk of burns from dangerous voltage
Power terminals may also carry voltage in the switched-o state or when the motor is stopped
and may cause life-threatening cardiac arrhythmia and serious burns.
▶Disconnect the product from the mains.
▶Check that the power terminals are deenergized before starng work.
•When working on energized products, comply with the applicable naonal accident
prevenon regulaons.
•The electrical installaon must be carried out according to the appropriate regulaons
(e.g. cable cross-secons, fuses, PE connecon).
•The manufacturer of the system or machine is responsible for adherence to the limits
required in connecon with EMC legislaon.
Operaon on an external inverter
A max. pulse voltage amplitude of Upk = 1560 V at the motor terminals must not be exceeded.
Here, the minimum pulse rise me must be tR = 0.1 µs.
If it cannot be ruled out that the permissible voltage peaks will be exceeded or that the
minimum pulse rise me will not be reached, the following measures must be iniated:
•Reducon of the DC-bus voltage (threshold for brake chopper voltage)
•Use of lters, chokes
•Use of special motor cables
Preparaon
The notes for the electrical connecon can be found in the enclosed mounng
instrucons.
EMC-compliant wiring
The EMC-compliant wiring is described in detail in the documentaon of the
Lenze inverters.

Motor connecon
Connecon via terminal box
Observe the notes on wiring, data on the nameplate, and the connecon diagram in the
terminal box.
The connecon must ensure a connuous and safe electrical supply:
•No protruding wire ends
•Use assigned cable end ngs
•Ensure good electrical conducvity of the contact (remove paint residues) if an addional
PE connecon is used
•Establish a safe protecve earth connecon
•Aer the connecon is completed, make sure that all connecons on the terminal board
are rmly ghtened
•The terminal box has to be free of foreign bodies, dirt, and humidity
•All unused cable entries and the terminal box itself must be sealed so that they are dust-
ght and waterproof
The smallest air gaps between uncoated, live parts and against earth must not fall below the
following values:
