2 General Safety Instructions
The products are developed and built according to the state of the art and recog-
nized safety rules. Nevertheless, their use may create dangers to life and limb of
the user or third parties or damage to the machine and other material property.
The following safety instructions have been created by the manufacturer for the
area of electric drive technology. They can be supplemented by local, country- or
application-specific safety instructions. This list is not exhaustive. Non-observance
of the safety instructions by the customer, user or other third party leads to the loss
of all resulting claims against the manufacturer.
NOTICE Hazards and risks through ignorance!
a) Read the instructions for use.
b) Observe the safety and warning instructions.
c) Ask if something is unclear.
2.1 Installation
DANGER Electrical voltage at terminals and in the device!
Danger to life due to electric shock !
üFor any work on the device
a) Switch off the supply voltage.
b) Secure it against switching on.
c) Wait until all drives has been stopped in order that no regenerative energy can
be generated.
d) Await capacitor discharge time (min. 5 minutes). Measure DC voltage at the
terminals.
e) Never bridge upstream protective devices. Also not for test purposes.
NOTICE Use of unsuitable voltage sources!
Electric Shock!
a) Use for the connection only suitable voltage sources with safe isolation (SELV/
PELV) in accordance with VDE 0100 with nominal voltage of DC 24 V ±10 %.
b) Pay attention on a sufficient overvoltage category of the voltage supply.
c) With existing or newly wired circuits the person installing the units or machines
must ensure that the PELV requirements are met.
For a trouble-free and safe operation, please pay attention to the following instruc-
tions:
– The electrical installation shall be carried out in accordance with the relevant
requirements.
– Cable cross-sections and fuses must be dimensioned by the user according to
the specified minimum/maximum values for the application.
– For drive converters that are not isolated from the supply circuit (in accordance
with EN 61800-5-1) all control lines must be included in other protective meas-
ures (e.g. double insulation or shielded, earthed and insulated).

General Safety Instructions | 2
ma_dr_f6-cu-k-inst-20144795_en 11
– When using components without isolated inputs/outputs, it is necessary that
equipotential bonding exists between the components to be connected (e.g. by
the equipotential line). Disregard can cause destruction of the components by
equalizing currents.
2.2 Start-up and operation
The start-up (i.e. the starting of normal operation) is prohibited until the machinery
has been proved to conform to the provisions Directive 2006/42/EG and Directive
2014/30/EU; EN 60204-1 must be observed.
WARNING Wrong parameterization
Unintentional behaviour of the drive
üDuring initial start-up or replacement of the drive controller
a) Secure motors against automatic restart.
b) Check whether the appropriate parameter list for the application has been im-
ported.
WARNING Software protection functions as sole protection.
Protection function in case of software problems without function.
üSecuring a unit solely with software-supported functions is not sufficient.
a) Install external protective measures (e.g. limit switch) that are independent of
the drive controller.
2.3 Maintenance
DANGER Unauthorized exchange, repair and modifications
Unpredictable malfunctions
a) The function of the drive controller is dependent on its parameterization. Never
replace without knowledge of the application.
b) Modification or repair is permitted only by KEB Automation KG authorized per-
sonnel.
c) Only use original manufacturer parts.
d) Infringement will annul the liability for resulting consequences.

4 Connection of the control
Observe the following instructions to avoid malfunctions!
– Install control cables and power cables separately (approx. 10…20 cm dis-
tance); Lay crossings in a right angle.
– In case of inductive load on the relay outputs a protective wiring must be
provided (e.g. free-wheeling diode).
– Electro magnetic interferences can be prevented by the following measures:
– Always use twisted and shielded cables for analog control lines. Connect
the shield at one side at the signal source.
– Twist digital control cables. Up from 3 m a shield may be required. In this
case connect the shield at both ends.
– Connect the shield of the brake and temperature monitoring together with
the motor shield. Leave the inner shields longer in order to avoid interfer-
ence coupling or decoupling (the latter during temperature measurement)
as far as possible.
The terminals of the control terminal block, enocder inputs and communication in-
terface are securely isolated in accordance with EN 61800-5-1.
4.1 Assembly of wires
NOTICE Loose and slack cable connections!
Malfunctions due to loose contacts.
a) Observe metal sleeve length and stripping length according to table.
b) Use a suitable pressing tool.
c) Make sure that all wires are inserted into the wire-end sleeve.
d) After inserting the cable into the terminal, check that it is firmly seated.
