Damage due to improper transport
► Transportonlyonsuitabledevices(foldingboxes,transportframes,at
pallets, usw) !
►Avoid any impacts, sharp sudden movements and strong vibrations!
►Motors must only be lifted and placed at creeping speed to prevent dam-
age to the bearings !
Do not store Motors
• in the environment of aggressive and/or conductive liquids or gases.
• with direct sunlight.
• outsidethespeciedenvironmentalconditions.

14
BASIC SAFETY INSTRUCTIONS
To prevent damage to the motor:
• Checkifnecessaryanddonotremoveanti-corrosivecoatattheshaftends,ange
surfaces etc.
• No vibrations may occur in the storage location.
• In case of storage longer than 3 months, rotate the motor in both directions at a slow
speed (< 100 rpm) to allow the grease to distribute evenly in the bearings.
• If necessary, rotate the rotor at least once a year several times, in order to avoid
corrosion on the bearings.
1.3 Installation
DANGER Do not operate in an explosive environment!
EX
►The motors are not intended for the use in potentially explosive
environment.
CAUTION Maximum design edges and high weight!
Contusions and bruises!
►Never stand under suspended loads.
►Wear safety shoes.
►Secure motor accordingly when using lifting gear.
To prevent damages to the motor:
• Make sure that isolation distances will be respested in the terminal box.
• Before commissioning motors with a shaft key, secure the key to ensure that it can-
not be thrown out if this is not already prevented by driving elements such as a belt
pulley, coupling, etc.
• The motor must not be put into operation in case of mechanical defects. Non-
compliance with the applicable standards.
• Do not allow moisture or mist to penetrate the motor.
• Avoid dust permeating the device.
• Note installation position and minimum distances to surrounding elements. Do not
cover the ventilation openings.
• Make sure that no small parts fall into the motor during assembly and wiring (drilling
chips, screws etc.). This also applies to mechanical components, which can lose
small parts during operation.
• Check the reliable t of the terminals in order to avoid contact resistances and
sparking.
• Do not climb on the motor housing.
• The safety instructions are to be kept!

15
BASIC SAFETY INSTRUCTIONS
1.4 Connection instructions
DANGER Voltage at the terminals and in the motor!
Danger to life due to electric shock!
►Never work on the open motor or never touch exposed parts.During
the operation (even at zero speed) the motors posses dangerous
live parts.
►For any work on the motor switch off the supply voltage and secure
it against switching on.
►Wait until the drive has stopped in order that no regenerative energy
can be generated.
►Never bridge upstream protective devices (also not for test pur-
poses).
►Connect the protective earth conductor to drive converter and motor.
►Install all required covers and protective devices for operation.
For a trouble-free and safe operation, please pay attention to the following instructions:
• The electrical installation shall be carried out in accordance with the relevant re-
quirements.
• The motors are not designed for direct connection to the three-phase system but are
to be operated via an electronic power inverter.
• Connect the temperature sensor to protect the motor against slow thermal chang-
es. Temperature sensors do not represent an all-around protection of the winding.
Measures must be taken in the parameterisation of the inverter for the protection
against fast thermal changes (e.g. I2´t-monitoring) !
• Check the proper functioning of the brake (optional).
• An optional holding brake is only designed for a limited number of emergency brak-
ings. Never use it as a working brake.On motors with plug connector and built-in
brake, it is the user's responsibility to install the varistor provided to control the
brake.
Installations which include drive converter shall be equipped with additional control and
protective devices in accordance with the relevant applicable safety requirements, e.g.
act respecting technical equipment, accident prevention rules etc. They must always be
complied with, also for drive converter bearing a CE marking.

16
BASIC SAFETY INSTRUCTIONS
1.4.1 EMC-compatible installation
Observance of the limit values required by EMC law is the responsibility of the manufac-
turer of the installation or machine.
Notes on EMC-compatible installation can be found here.
0000ndb0000.pdf
1.5 Start-up and operation
The drive converter must not be started until it is determined that the installation com-
plieswiththemachinedirective;AccountistobetakenofEN 60204-1.
WARNING Software protection and programming!
Hazards caused by unintentional behavior of the drive!
►Check especially during initial start-up or replacement of the drive
converter if parameterization is compatible to application.
►Securing a unit solely with software-supported functions is not suf-
cient.Itisimperativetoinstallexternalprotectivemeasures(e.g.
limit switch) that are independent of the drive converter.
►Secure motors against automatic restart.
CAUTION High temperatures at heat sink and coolant!
Burning of the skin!
►Cover hot surfaces safe-to-touch.
►Before working let the motor cool down.
►Before touching, check the surface and cooling water lines.
►If necessary, attach warning signs on the system.

17
BASIC SAFETY INSTRUCTIONS
Switching at the output
Switching between motor and drive converter is prohibited for single drives during op-
eration as this may trigger the protection gear of the device. Function speed search must
be activated if switching can not be avoided. Control release may only be triggered after
closing the motor contactor (e.g. by switching the control release).
Connecting and disconnecting is permissible with multiple motor drives if at least 1 mo-
tor is running during the switch-over process. The drive converter must be dimensioned
to the occurring starting currents.
The speed search function must be activated if the motor is still running during a restart
of the drive converter (mains on) (e.g. due to large rotating masses).
1.6 Maintenance
Die folgenden Wartungsarbeiten sind nach Bedarf, mindestens jedoch einmal pro Jahr,
durch autorisiertes und eingewiesenes Personal durchzuführen.
►Check unit for loose screws and plugs and tighten if necessary.
► Cleanmotorfromdirtanddustdeposits.Payattentionespeciallytocoolingnsand
protective grid of the fans.
►Check the function of the fans of the drive converter. The fan must be replaced in
case of audible vibrations or squeak.
1.7 Repair
In case of malfunction, unusual noises or smells inform a person in charge!
DANGER Unauthorized exchange, repair and modications!
Unpredictable malfunctions!
► ModicationorrepairispermittedonlybyKEBAutomationKGau-
thorized personnel.
►Only use original manufacturer parts.
