BASIC SAFETY INSTRUCTIONS
1 Basic Safety Instructions
The COMBIVERT is designed and constructed in accordance with state-of-the-art tech-
nology and the recognised safety rules and regulations. However, the use of such devic-
es may cause functional hazards for life and limb of the user or third parties, or damages
to the system 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-
specicsafetyinstructions.Thislistisnotexhaustive.Non-observancewillleadtothe
loss of any liability claims.
Attention Hazards and risks through ignorance.
►Read the instruction manual !
►Observe the safety and warning instructions !
►If anything is unclear, please contact KEB Automation KG !
1.1 Target group
This instruction manual is determined exclusively for electrical personnel. Electrical per-
sonnelforthepurposeofthisinstructionmanualmusthavethefollowingqualications:
• Knowledge and understanding of the safety instructions.
• Skills for installation and assembly.
• Start-up and operation of the product.
• Understanding of the function in the used machine.

BASIC SAFETY INSTRUCTIONS
1.4 Electrical connection
DANGER Voltage at the terminals and in the device!
Danger to life due to electric shock !
►Never work on the open device or never touch exposed parts.
►For any work on the unit 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.
►Await capacitor discharge time (5 minutes) if necessary, measure
DC voltage at the terminals.
►If personal protection is required, install suitable protective devices
for drive converters.
►Never bridge upstream protective devices (also not for test pur-
poses).
►Connect the protective earth conductor to drive converter and mo-
tor.
►Install all required covers and protective devices for operation.
►The control cabinet shall be kept closed during 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.
• Cable cross-sections and fuses must be dimensioned according to the design of
themachinemanufacturer.Speciedminimum/maximumvaluesmaynotbefallen
below /exceeded.
• Drive converters are only intended for permanent connection. Cross-sections of pro-
tective earth conductors should be interpreted in accordance with EN 61800-5-1.
• Connection of the drive converter is only permissible on symmetrical networks with
a maximum line voltage (L1, L2, L3) with respect to earth (N/PE) of max. 300 V. An
isolating transformer must be used for supply networks which exceed this value.
In case of non-compliance the control is not longer considered as "safe separate
circuit".
• With existing or newly wired circuits the person installing the units or machines must
ensure the EN requirements are met.
• 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 measures (e.g.
double insulation or shielded, earthed and insulated).
• When using components without isolated inputs/outputs, it is necessary that equi-
potential bonding exists between the components to be connected (e.g. by the equi-
potential line). Disregard can cause destruction of the components by equalizing
currents.

BASIC SAFETY INSTRUCTIONS
If personnel protection is required during installation of the
system, suitable protective devices must be used for drive
converters.
ti_rcd_0400_0002_gbr.pdf
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.
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.

1.4.2 Voltage test
Testing with AC voltage (in accordance with EN 60204-1 Chapter 18.4) may not be ex-
ecuted, since there is danger for the power semiconductors in the drive converter.
Because of the noise suppression capacitors the test generator will immediately trigger
with current error.
Accordng to EN 60204-1 it is permissible to disconnect already tested com-
ponents. Drive converters of the KEB Automation KG are delivered ex works
voltage tested to 100% according to product standard.
1.4.3 Insulation measurement
An insulation measurement (in accordance with EN 60204-1 chapter 18.3) with DC
500 V is permissible, if all power unit connections (grid-connected potential) and all con-
trol connections are bridged with PE. At any unit it can be expected with an insulating
resistance>5MΩ!

BASIC SAFETY INSTRUCTIONS
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 unit cool down.
►Before touching, check the surface and cooling water lines.
►If necessary, attach warning signs on the system.
• During operation, all covers and doors shall be kept closed.
• Use only approved accessories for this device.
• Never touch terminals, busbars or cable ends.
Observe the following instructions if the drive converter for
more than one year was not in operation before start-up.

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).

BASIC SAFETY INSTRUCTIONS
Switching an the input
For applications that require cyclic switching on and off of the drive converter, main-
tain an off-time of at least 5 min. If you require shorter cycle times please contact
KEB Automation KG.
Short-circuit proof
The drive converters are conditional short-circuit proof. After resetting the internal pro-
tection devices, the function as directed is guaranteed.
Exceptions:
• If an earth-leakage fault or short-circuit often occurs at the output, this can lead to a
defect in the unit.
• If a short-circuit occurs during regenerative operation (2nd or 4th quadrant, regen-
eration into the DC link), this can lead to a defect in the unit.
1.6 Maintenance
The following maintenance work has to be carried out when required, but at least once
per year by authorized and trained personnel.
►Check unit for loose screws and plugs and tighten if necessary.
►Clean drive converter from dirt and dust deposits. Pay attention especially to cool-
ingnsandprotectivegridofthefans.
► Examineandcleanextractedairlterandcoolingairlterofthecontrolcabinet.
►Check the function of the fans of the drive converter. The fan must be replaced in
case of audible vibrations or squeak.
►Make a visual leak test of the cooling circuit for water-cooled inverters.
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!
►The function of the drive converter is dependent on its parameteri-
zation. Never replace without knowledge of the application.
► ModicationorrepairispermittedonlybyKEBAutomationKGau-
thorized personnel.
►Only use original manufacturer parts.
►Infringement will annul the liability for resulting consequences.
In case of failure, please contact the machine manufacturer. Only the machine manu-
facturer knows the parameterisation of the used drive converter and can provide an
appropriate replacement or induce the maintenance.

1.8 Disposal
Drive converters with safety function are limited to a service life of 20 years. Then the
devices must be replaced.
Drive converters of the KEB Automation KG are professional, electronic devices exclu-
sively for further industrial processing (so-called B2B devices). Thus the marking does
not occur with the symbol of the crossed-out wheeled bin, but by the word mark and the
date of manufacture.
Unlike devices mainly used in private households, these devices may not be disposed
at the collection centres of public sector disposal organisations. They must be disposed
after the end of use in accordance with national applicable law to environmentally cor-
rect disposal of electrical and electronic equipment.
