1 SAFETY INFORMATION
Preliminary Remarks
During operation, the principles on which the power converter and the motor work lead to leakage
currents to earth that may be dissipated via the specified protective earths and may result in a currentoperated e.l.c.b. on the input side blowing prematurely.
In the case of a short-circuit to frame or to ground, a direct proportion may arise in the leakage current
that makes triggering a higher-level current-operated e.l.c.b. either more difficult or totally impossible.
This means that connecting the power converter to the mains using only the current-operated e.l.c.b.
is prohibited (preliminary standard EN 50178/VDE 0160/11.94, Sections 5.2.11 and 5.3.2.1).
The units are protected from direct contact by being installed in commercially available switching cabinets that meet the minimum protection requirements of preliminary standard EN 50178/VDE
0160/11.94, Section 5.2.4.
Sheets of plastic covering the equipment connection act as additional guards preventing accidental
contact at commissioning and in the case of casual use of control elements located close to the
equipment (DIN VDE 0106 Part 100, Accident Prevention Regulation VBG4 "Electrical Systems and
Equipment").
At routine testing of this equipment, a high-voltage test is carried out that conforms with preliminary
standard EN 50178/VDE 0160/11.94, Section. 9.4.5.
The protective measures and safety regulations according to DIN/VDE are binding for personal security.
Neglecting to fit PE connections on the equipment or the motor will result in serious personal injury
and/or considerable damage to property.

2 TECHNICAL DATA
2.1 General
The motor and the converter must be matched to one another to be able to fulfil the requirements
made of the drive system three-phase current servo motor and the converter. Our BAUMOTRONIC
converters, which have been specially developed for servo drives, are transistor converters for fourquadrant operation.
The BAUMOTRONIC converter system is of modular structure and comprises the following units:
− the BUG basic feed unit
− the BUS servo power unit
The BUG 2/3/20 named basis feed units are mains-side power converters for feeding the BUS 3/21/20
drive amplifiers. They have a ballast circuit to dissipate the drive´s breaking energy. They are available
with internal ballast resistor or, as E version with a connector for external resistors.
Features:
− BUG 3 basic unit for up to 10.5 kW
− BUG 2 basic unit for up to 18 kW
− BUG 20 basic unit for up to 36 kW
− Connection using a pre-transformer of 400 V/230 V 3 ∼
− Servo power units' current supplied from the intermediate circuit
− Switching power supply with wide voltage range continues to be ready-for-use while the inter-
mediate circuit is charged
− Ballast circuit with high peak power integrated in the basic feed unit

Technical DataGeneral
2.1.1 Description of Function
Intermediate Circuit
The intermediate circuit, which supplies the connected servo units, is fed from the mains via an external matching transformer and the uncontrolled bridge rectifier.
Starting Current Limitation Device
If no measures were taken, the intermediate circuit capacitors would lead to inadmissibly high charging current surges when you switch on the mains current. Mains transformers of up to 5 kVA automatically reduce the charging current surge to a non-dangerous level. In the case of large transformers,
you must install a starting current limitation device on the input side.
This device is shunted out after the start-up stage.
Power Supply
The internal switching power supply generates the supply voltages for the connected servo units from
the intermediate circuit or from an external auxiliary voltage.
In addition, permanent monitoring is carried out of the temperature, the intermediate circuit voltage,
the supply voltages and the ballast function. In the case of inadmissible values, the system issues a
message that is further-processed appropriately.
The system indicates these messages to you directly by means of LEDs.
Ballast
When the drive is operating in regenerative mode, it feeds back to the intermediate circuit and raises
its voltage. If this voltage exceeds an impermissibly high value, the integrated ballast transistor
switches the ballast resistor (which can be external if desired) to the intermediate circuit and removes
the excess energy.

5.1 Danger Information
WARNING
This equipment carries a dangerously high voltage and has dangerous rotating parts (fans). Ignoring
the safety and warning information may result in death, severe personal injury or damage to property.
The machine operator is responsible for mounting the mono power unit, the motor, the transformer
and any other equipment in accordance with appropriate safety regulations (e.g. DIN, VDE); equally,
you must ensure that all other relevant national and local regulations are met with regard to cable ratings and protection, grounding, disconnectors, overcurrent protection, etc.
If you carry out works at power-on drive converters you must obey the national safety rules to avoid
accidents. The electrical installation must be carried out according to the resoective guidelines (e.g.
cross-sections, fuses, protective earth attachment).
The protective earth connection has to be carried out according to DIN EN 60204/VDE 0113
Part1/06.93; section 8.2.2, also pr EN 50178/VDE 0160/11.94, sections 5.3.2 and 8.3.4, or the respective local guidelines. Information about EMC-correct installation – as screeening, earthing, positioning of filters and running cables, you will find in this document. This information must be respected
also when using CE-marked drive converters.
The responsibility for keeping the limits requested by the EMC laws has the manufacturer of the plant
or machine.
Relatively high leakage to ground occurs in the converter and the motor, i.e. the drive may be incompatible with current-operated e.l.c.b.s (corresponding to provisional standard EN 50178:1994 Section
5.2.11.2).
You must only use variable-speed drives in applications that correspond to valid EN specifications.
DANGER
The intermediate circuit carries a voltage!
Be particularly careful before touching the drive shaft directly or indirectly with your hands. This is only
allowed when the system is deenergized and the drive is stationary.
Safety devices must never be deactivated.

5.2 EMC Information
General Information about Converters
Modern semiconductor technologies such as MCTs and IGBTs are intended to minimize the power
loss in the converter by switching more quickly and, with this, to continually reduce the size of the
power section. As a result, when running converters you must meet specific conditions to avoid electromagnetic influences caused by switching operations.
Disturbances can occur due to:
• capacitive fault currents caused by high rates of voltage rise when bipolar transistors and IGBTs
switch.
1 Feed
2 Power section
3 Switching power supply
4 Motor
• high currents and high rates of current rise in the motor lines. The disturbance energy bound in mag-
netic fields reaches frequencies of between a few Hertz and about 30 MHz. Due to the high rates of
current rise, additional electromagnetic fields occur with frequencies of up to approximately 600 MHz.
• high clock rates and fast logic circuits (electromagnetic field/16 MHz...1 GHz).
• system perturbation and harmonics caused by commutations and non-sinusoidal network loading,
in particular with line-commutated converters (100 Hz ... 20 kHz).
German EMC Law (EMVG)
This converter complies with Paragraph 5, Section 5, Sentence 3 of the German EMC Law (EMVG)
dated 09.11.92.
"Devices that are exclusively manufactured or stocked as vendor parts or spare parts for further processing
by industrial companies or craftsmen or by other specialists in the field of electromagnetic compatibility do
not need to comply with the protective requirements of Paragraph 4,
formity certification and marking, assuming that the devices in question cannot be run automatically."
Section 1, nor do they need EU con-
This does justice to the fact that EMC is heavily dependent on the individual subassemblies and components in the switching cabinet. With regard to the total costs of the machine, it is preferable to troubleshoot an entire system rather than each of its individual components.

• You achieve the lowest possible effective antenna height by routing the cable directly on the
ground of the metallic rack.
WrongRight
• You should route all lines as close as possible to the conductors of the ground system to reduce
the effective loop area for magnetic coupling.
WrongRight
• When parallel-routing signal and control lines across power cables, the conductors must be at least
20 cm apart.
• Lines of different EMC categories should only cross at an angle of 90°.
• In the case of symmetrical signal transfer (e.g. differential amplifier inputs for the speed specified
value), twist the conductors of each pair of wires together and twist the pairs of wires together.
• The converter to ground plate earth-connection should be as short as possible (less than 30 cm).
Use large cross-sections (more than 10 mm²).
• Sources of interference such as fuses, transformers and chokes and modules that are sensitive to
interference like µPs, bus systems, etc. should be located at least 20 cm away from the converter
and its cabling.
20BUG 3/2/20 Basic Feed Unit
5.96064.02Baumüller Nürnberg GmbH
Page 29
EMC InformationInstallation
• Avoid reserve loops on overlong cables.
• You must ground reserve lines at both ends (this has an additional screening effect, avoids ca-
pacitively coupled, dangerous touch voltages).
Grounding
• From an EMC point of view, classical star grounding is no longer adequate for reducing the influ-
ence of disturbances at relatively high frequencies that occur as a result of converter operation.
Better results can be achieved by a reference surface that must be linked to the devices' frame
grounds over a wide area (e.g. a bare, metallic mounting plate and parts of the housing).
If it is not possible to use a broad reference place, it is sensible to mount the main equipotential
busbar directly next to the converter, since this device generates the greatest potential jumps,
compared with the other components in the switching cabinet, due to the steep switching edges
(the ground connection should be less than 30 cm long if possible).
• Route all earth conductors and screens as closely as possible above the frame ground to prevent earth
circuits.
• If it is possible to earth the controller reference voltage, make this connection with cabling that has
as large a cross-section as possible and is less than 30 cm long.
• Remove insulating layers, such as varnish, adhesives, etc., from the frame ground connections. If nec-
essary, use DIN 6798 serrated lock washers or similar to ensure a permanent, conductive contact. To
prevent corrosion of frame ground connections, use suitable pairs of metals (electrochemical displacement series), and keep conductive electrolytes away from the connection by means of a protective
coating (e.g. grease).
• Always connect screens at both ends to the frame ground; the connection should be over a wide
area and conductive. This is the only way to suppress the effects of magnetic or high-frequency
noise interference fields. If there are problems with earth circuits (e.g. double earth fault of the
specified value conductor screen), the receive side should be galvanically connected and the
transmit side capacitively connected.
• When routing cable screens through panels that separate different EMC areas, the cables must be
in contact with the panel.
Cables that are routed through the outer panels of screening housings without special measures
(e.g. filtering), can have an adverse effect on the screening capability of the housing. For this reason, you must make a conductive connection of the cable screens to the screening outer panel at
the point at which the cable enters the housing.
The distance of the last screen contact point to the exit from the cabinet must be as short as possible.

InstallationEMC Information
Screening
• The screen is effective against magnetic fields if it is connected to frame ground at both ends.
With electrical fields, the screen is effective when it is connected to frame ground at one end.
However, in the case of (electrical or magnetic) fields with high frequencies (depending on the
length of the line), you must always connect the screen at both ends due to the linkage (electromagnetic field).
Connecting the screen to frame ground at both ends ensures that the conductor does not leave the
screening "system housing".
• Frame-grounding of conductor screens on both sides does not entirely rule out the influence of
earth circuits (potential differences on the frame ground system). However, this is very rare if you
carry out the measures described in the previous sections entitled "Cabling" and "Grounding".
You can also make a capacitive RF connection of a screen to frame ground. This prevents lowfrequency interference due to earth circuits.
Screened cables that pass through different EMC areas must not be separated at terminals, since
screen damping would otherwise be considerably reduced. The cables should be routed to the next
module without interruption.
• Make the screen connection low-impedance and over a wide surface area. Cable tails that are only
three centimetres long (1 cm of wire = 10 nH) reduce the screening effect in the megahertz range
by up to 30 dB!
NOTE
The braided screen must have a coverage of at least 85%.
The following lines have particularly high levels of interference potential:
− the motor line
− the line to the external ballast resistors
− the line between the mains filter and the converter

EMC InformationInstallation
• Suggestion for screen connection:
Filtering
No filters are needed for the converter to function. However, under some circumstances, filters may be
needed on the input or the output side to comply with EMC regulations.
If you have any queries about filter design, please ask for the description entitled “Baumüller Filters for
Network Applications, BFN”.
Filter Assembly
• Mount the filter directly next to the converter. With lines that are more than 30 cm long, you must
screen the mains line between the converter and the filter (frame-ground on both sides).
• Physically separate the filter's input and output lines by more than 30 cm.
• Make a broad connection between the filter housing and frame ground.
Discharge Currents
Due to the principle of operation, parasitic capacities in the filter, the mains unit, the motor cable and
the motor winding cause discharge currents of around 100 mA and higher.
This means that converters with earth leakage circuit-breakers may be incompatible!
In this context, you should observe the safety information in provisional standard EN 50178:1994 Section
5.2.11.2.

5.5.3 BUR Resistor Unit
Device Description
During the braking stage of converter-fed three-phase current drives, the system initially loads
the device-internal intermediate circuit capacitors with the fed-back electrical energy.
If there is still electrical energy available after loading, it can be additionally stored in an external capacitor unit or converted to heat via device-internal or device-external resistors. Specifically for the latter purpose, a Type Series 6 device is provided that combines the resistors in a
force-ventilated way in a safe housing.

5.5.4 BUK Capacitor Unit
Device Description
In the case of converter-fed three-phase current drives that are primarily used as acceleration
drives, e.g. as transverse cutting drives, it is frequently practical to supplement the internal
intermediate circuit capacitor by adding an external capacitor unit. This makes it possible to
store the energy that is fed back at braking of the drive.
Due to the use of a capacitor unit, it may be possible to replace a ballast unit that normally
converts the fed-back energy to heat. In addition, a capacitor unit is always used in cases
where the intermediate circuit voltage must be maintained during brief mains failures.
BUK external capacitor units are integrated in Type Series 6 housings and are available for
intermediate circuit voltages of 310 V and 540 V.

Plants that have drive converters installed, must have additional monitoring and protection devices
according to the respective regulations, e.g. technical equipment regulations, safety precautions etc.
Alterations of the drive converters or the operation software are prohibited.
This equipment carries a dangerous voltage and contains dangerous rotating parts (fans). Ignoring the
safety and warning information may result in death, severe personal injury or damage to property.
Only qualified personnel which has been instructed with all safety-related information as well as the
mounting-, service- and maitenance instructions given in this document is allowed to operate this device.
You are responsible for mounting the Mono power unit, the motor and any other equipment in accordance with appropriate safety regulations (e.g. DIN, VDE); equally, you must ensure that all other
relevant national and local regulations are met with regard to cable ratings and protection, grounding,
disconnectors, overcurrent protection, etc.
The most important factors for protecting people are the DIN/VDE protective measures and safety
regulations. If there are no protective earth connections on the equipment, commutating reactor or the
motor, personal injuries are inevitable, since the surfaces may carry dangerously high voltages.
The mains unit and the field connector of the power converter carry a dangerous voltage even when
the main contactor has dropped. Do not touch these modules when under power. Connect test equipment only in powerless state!
After the drive converter is separated from the power supply you must not touch any connectors as
they still might carry dangerous loads. Observe the waiting time given on the danger sign information
on the drive converter.
During operation, the principles on which the power converter and the motor work lead to leakage
currents to earth that are dissipated via the specified protective earths and may result in a currentoperated e.l.c.b on the input side blowing prematurely.
In the case of a short-circuit to frame or to ground, a direct proportion may arise in the leakage current
that makes triggering a higher level current-operated e.l.c.b. either more difficult or totally impossible.
The connection of the converter to mains using only an e.l.c.b. is prohibited (refer to pr EN
50178:1994 section 5.2.11.2 and appendix A 5.2.11.2 diagram 7).
Before carrying out commissioning, check whether the plastic covers over the power stage connections are in place.
The appliances are only to be operated on earthed mains systems.
The discharge time of the power conducting parts is more than 1 minute.

WARNING
Irregular drive behavior
During initial commissioning, faulty or uncontrolled motion of the driven machine elements is always
possible. At this stage, you should therefore proceed with particular care.
Before switching on the drive, you must carefully check the functions of all the higher level safety
equipment to prevent personal injury.
Take particular care when directly or indirectly touching the drive shaft with your hand. This is only
allowed when the shaft is stationary and the power converter is deenergized. Any exposed parts of the
machine, such as the shafts, fans, etc., must be covered during operation.
Contact Protection In Accordance with Paragraph 4 Section 4 VBG 4 (German safety regulation)
Protection against direct contact comprises all the measures against danger that can result from
touching the active parts of electrical equipment.
You must therefore protect the active parts from being touched by means of insulation, the construction
and arrangement of the equipment or directly mounted guards. The guards in question are standard
covers, barriers and procedures that guarantee that people cannot touch active parts that are carrying
power.
Switching cabinets must have an emergency off facility to switch off any voltages that could be dangerous. This does not include equipment which, if switched off, would cause an even more dangerous
situation. The emergency off releasing element must be arranged in such a way that it can be reached
quickly in case of danger. In the case of work that is considerably more dangerous than usual, another
person must be present.
The operator must ensure that unauthorized people do not work at the machine.
The operator must report immediately any changes that occur at the machine which adversely affect
safety.
When dismounting safety equipment during commissioning, repair and maintenance, you must ensure
that the machine is taken out of commission in accordance with applicable regulations. You must remount and check safety equipment immediately after completing commissioning, repair and maintenance.

WARNING
Follow the safety information on the motor, tachometer and further electrical appliances in the respective operating and maintenance instructions.
Avoid any working practices that jeopardize safety at the machine.
After carrying out any work involving intervention in the drive – regardless of whether this involves the
motor, actual value acquisition or the power converter – the owner must carry our acceptance testing
of the machine and document it chronologically in the machine log (maintenance manual or similar).
Failure to do this may result in the owner being faced with consequences relating to liability legislation.
This is not a complete list of all the procedures necessary for safe operation of the unit. If you need
further information or have particular problems, contact BAUMÜLLER NÜRNBERG or one of our distributors.
Observe the warning information in chapter 1 of these operating instructions.
NOTE
•Before touching the modules, you must discharge electrostatic energy from your body to protect
electronic components from high voltages resulting from electrostatic charging. The easiest way to
do this is to touch a grounded conductive object before handling components.
Units containing components or modules at risk from electrostatic energy are clearly marked as
such by the sticker below.

•Ready-for-Use
If no message is pending, the green ready-for-use LED is lit and the system reports this condition
to the servo units. If only one message of the BUS servo units is pending and the group message
on the servo units is activated in the BEDAS, the system cancels ready-for-use and does not indicate any further messages.
•Intermediate Circuit
If the intermediate circuit voltage exceeds the set limit value, the system issues a message and
displays it. Ready-for-use is cancelled.
This message is issued in the following cases:
− braking energy is greater than P

Messages and WarningsCommissioning
•Ballast
Ballast monitoring supervises the switching frequency of the ballast transistor. If the maximum time
exceeeds the internally set time, the system issues a message and cancels ready-for-use.
This message is issued in the following cases:
− if the braking power is too high
− if the continuous power of the ballast resistor is too high
− if the short-time loading is longer than two seconds
− if the intermediate circuit voltage due to the mains overvoltage is greater than 375 V
• Controller Supply
Controller supply monitoring supervises the internal switching power supply for overloading and
brief short-circuits. If one of these errors occurs, the system generates a message and cancels
ready-for-use.
•Temperature
Overtemperature monitoring supervises the temperature of the heatsink. If this temperature exceeds an internally set limit value, the system issues a message and cancels ready-for-use.
This message is issued in the following cases:
− if the input rectifier is overloaded
− if the fan is blocked
− if the ambient temperature is too high
• System error
If the system issues one of the messages listed above, it is stored and displayed as the System error group message.
The system cancels ready-for-use and reports it to the connected servo units.
NOTE
You cannot clear messages whose disturbances are still pending.

prerequisites he is obliged to m eet
− Date on which a downpayment or security required prior to deliver y of the

3.4 Baumüller is not responsible for delayed delivery or p erformance or the inability to deliver or
perform due to acts of god or force majeure or other eve nts which make it impossible or more
difficult for Baumüller to deliv er - e.g. war, problems in the provision of materials which arise
after the time the offer has been made, m alfunctions, strike, lockout, personnel short age,
shortages of means of transportation, instruc tions issued by the authorities etc. which occur at
suppliers of Baumüller or their sub-s uppliers. Therefore, Baumüller has the right to postpone
deliveries or performance by the durat ion of the problem plus an appropriate startup tim e and
Baumüller also has the right to withdra w from the contract partially or completel y. If the problems persist for more than 3 months the pur chaser has the right to withdraw from that part of

of Baumüller at the costs of the custom er. The risk is passed to the customer as soon as t he
consignment has been handed over to the per son carrying out the transport or has left the
store.
4.2 If the shipment is delayed or becomes impossible due to reasons for whic h Baumüller is not
responsible, the risk is passed to the c ustomer with the notification of readiness for s hipment if
the delivery is stipulated to be carried out upon call-forw ard notice, the goods are regarded as
called off at the latest one year after th e date of order.
4.3 Special acceptance conditions must be defined at c onclusion of the contract at the latest. The
acceptance test has to take place in the works of Baumüller. The costs for the acceptance test
will be charged to the customer. If the cus tomer omits the acceptance test, the goods are regarded as delivered as stipulated when they leave our works.
5. Prices and terms of payment
5 1 The prices stipulat ed by Baumüller in the order confirmation plus t he respective legal value
added tax apply. Additional deliveries and servic es will be separately invoiced. The prices are
valid ex works or store excluding pac king.
5 2 If not otherwise agreed upon, the prices stipulated in the order confirmation are binding for 30
days only.
5 3 Payments shall be made in cash without any deductions free paying office of the vendor in t he
currency agreed upon. Bills of exchange and ch ecks are only accepted on account of payment. The customer has to bear any costs and bank charges arising thereof.
A payment is regarded as made only, if the am ount is available to Baumüller. In case of payment by check, the payment is regarded as made when the check has been irrevocably
cashed.
5 4 Invoices are to be paid without deductions within 30 days from the date of issue. Baumüller is
entitled to enter payments of the cust omer on older open invoices in spit e of deviating instructions by the customer. If costs and interests have ahead arisen. Baumüller is entitled to enter
the payment first on the costs, then on the i nterests and last on the main service.
5.5 The customer is entitled to offset, to retain or red uce the payment - independent of notices of
complaint or possible countercla ims - only, if Baumüller has explicitly agr eed or if the counterclaims have been legally verifie d.
5.6 If payments are delayed, Baumüller is entitled to charge interest on arre ars at a rate corresponding to the interest rate for open cred its in current account, however, at least corresponding to the current discount rate of the Deutsche Bundesbank.
This does not affect the assertion of anot her damage caused by delayed payment.
5 7 If the customer fails to meet his payment obligations, esp ecially if he does not cash a chec k or
stops his payment or if Baumüller is informed of other circumstances making the cr edit worthiness of the customer uncertain. Baumüller is entitled to demand advance payments or secur ities before delivery or to invoice th e total remaining amount in the case that ins talments had
been previously agreed upon.
6. Retention of owners hip
6 1Until all claims for present or future relations have be en satisfied, Baumüller can at
any time demand securities from the custom er. Baumüller will arbitrarily release provided securities
if the value of the securities continuousl y exceeds the claims b y more than 20%.
6.2 Any goods delivered remain property of Baumüller u ntil payment has been made in full (=
delivery under proviso). Goods delivered under pr oviso are processed or reconfigured at
the purchaser's for Baumüller as the manuf acturer but without add itional obligations. If
Baumüller ownership rights are nullified becaus e the goods are integrated into or assembled to other objects, a portion of the owner ship rights of th e purchaser to that object
covering the amount in question is transferred to Baumüller. The purchaser k eeps the
property of Baumüller in custody for no charges.
6.3 The purchaser has - unless he is in delay of payment - the right to pr ocess and sell the
goods delivered under proviso in norm al business. However, he must not distress or
transfer ownership of the goods deliver ed under proviso by way of security. T he purchaser transfers any receivables aris ing from the selling of the goods or from another legal reason completely to Baum üller when the goods are received. Baumüller revocabl y
entitles the purchaser to collect the recei vables transferred to Baumüller o n the account
of Baumüller under his own name. Upon request b y Baumüller, the purchaser will revea l
the transfer.
6.4 If third parties access the goods delivered under prov iso, the purchaser will inform them
about the ownership rights of Baumüller and will immediately inform Baumüller. Any expenses and damages are paid for by the p urchaser.
6.5 If the purchaser violates any of the terms of the contrac t - in particular if he is in dela y of
payment - Baumüller has the right to repos es the goods delivered under proviso at the
cost of the purchaser or Baumüller has the right to requir e transfer of the restitution title
the purchaser has against third parties. If Baumüller r epossesses or distresses the goods
delivered under proviso, this does not m ean that Baumüller withdraws from the contract.
The right to receive payment for damages r emains unaffected by this.
7. Warranty
7.1 If the delivered products are faulty or fail to have pro perties guaranteed by Baumüller or if
the products become defective during th e warranty period because of faults which occurred or were caused during the process of manufacturing or in case of material defects

be submitted to Baumüller for testing on reques t in the condition in which the defect was
detected. Defective products must not be retur ned to Baumüller unless Baumüller requests in writing that the products are returned. Failure t o observe any of the regulations
specified above nullifies all warr anty claims against Baumüller.

or other specifications provided by the purchas er, Baumüller is responsible only for the
fact that the manufactured product meets the specifications. Baumüller is not responsible

overvoltages and chemical influenc es or to the replacement of par ts which are exposed
to natural wear.
The warranty is void if the custom er or a third party changes or repairs the units del ivered

7.7 In case of guarantee and/or warranty claims, the motor, the spare part or the unit shall be
shipped free of duty and with free packing after prior agre ement with Baum üller.
