1. Safety Instructions
Prior to performing any work on the unit the user must familiarize himself with the unit. This
includes especially the knowledge and observance of the safety and warning directions.
The pictographs used in this instruction manual have following meaning:
Danger Refers to danger of life by electric current.
Warning Refers to possible danger of injury or life.
Note Refers to tips and additional information.
1.1 Validity
Theinformationcontainedinthetechnicaldocumentation,aswellasanyuser-specicad-
vice in spoken and written and through tests, are made to best of our knowledge and in-
formation about the application. However, they are considered for information only without
responsibility. This also applies to any violation of industrial property rights of a third-party.
Inspection of our units in view of their suitability for the intended use must be done generally
by the user. Inspections are particulary necessary, if changes are executed, which serve for
the further development or adaption of our products to the applications (hardware, software
or download lists). Inspections must be repeated completely, even if only parts of hardware,
softwareordownloadlistsaremodied.
Controlling by
the user
Application and use of our units in the target products is outside
of our control and therefore lies exclusively in the area of respon-
sibility of the user.
Use under
special condi-
tions
The used semiconductors and components of KEB are develo-
ped and dimensioned for the use in industrial products. If the KEB
COMBIVERT is used in machines, which work under exceptional
conditions or if essential functions, life-supporting measures or an
extraordinarysafetystepmustbefullled,thenecessaryreliability
and security must be ensured by the machine builder.
1.2 Qualication
All operations serving transport, installation and commissioning as well as maintenance are to
becarriedoutbyskilledtechnicalpersonnel(observeIEC364orCENELECHD384orDINVDE
0100andnationalaccidentpreventionrules!).Accordingtothismanualqualiedstameans:

Danger by
high voltage
KEB electronics components contain dangerous voltages which
can cause death or serious injury. In operation, drive converters,
depending on their degree of protection, may have live, uninsulated,
and possibly also moving and hot surfaces.
In case of inadmissible removal of the required covers, of improper
use, wrong installation or maloperation, there is the danger of
serious personal injury and damage to property.
2. Service notes
2.1 General
The present service manual describes necessary steps at maintenance and repair of medi-
umfrequencysine-wavelters.
The following checks must be done.
•Capacity test of the capacitors
•Insulation test of the choke
2.2 Required tool
•Torque spanner with diverse uses
•Capacity measuring device
•High voltage tester
Additional equipment for the change of the capacitors
•Knife
•Hot-air fan
•Heat-shrinkable tube
2.3 Life expectancy - exchange of the capacitors
The maximum life expectancy of the capacitors amounts to100,000 operating hours. After
that the capacitors must be exchanged.
This information can deviate downwards dependent on the respective operating mode.
Whether an exchange is necessary results by the following measurement.
2.4 Checkingofthesine-wavelter
2.4.1 Preparations
•switch system de-energized
•secure against restart
• awaitveminutesfordischargeofthecapacitors
• cleansine-wavelterfromdustandothercontaminations
Service Manual for Medium Frequency Sine-wave Filters
GB-5
2.4.2 Measurements at the capacitor
Unscrew and mark connections of the capacitor at the terminal strip.
The capacity measurement must be executed as follows:
•It is measured between two phases of the delta-connected
capacitors.
•The following capacity value CMeas must result.
CMeas=1,5•Crated ±7,5 %
•A failure may occur if one of this three measured values
dierstotheother.Thecapacitormustbeexchangedin
accordance with chapter 3.
The high-voltage test is made dependent on the insulation tester with the following test
voltages:
Test voltage phase <-> ground
2,5 kV ac
3,5 kV dc
2.4.3 Measurement of the insulation strength
The choke can be checked with a high-voltage test on its insulation strength. The test is
done without capacitor.
Unscrew connections of the capacitor at the terminal strip
The high-voltage test is made dependent on the insulation tester with the following test
voltages:
Test voltage phase <-> phase Test voltage phase <-> housing
2,5 kV ac 2,5 kV ac
3,5 kV dc 3,5 kV dc
2.4.4 Connection of the capacitor lines
The capacitor lines must be connected again in accordance with the marking if the tests are
without complaint. The terminals must be tightened with the following tightening torque:
Terminal strip Tightening torque terminal strip
WFF 35 3,0…6,0 Nm
WFF 70 6,0…12 Nm
WFF 120 10…20 Nm
WFF 185 14…31 Nm
WFF 300 25…60 Nm

2.5 Exchange of the capacitors
2.5.1 Spare parts list
If the result of the test requires an exchange of the capacitors, they can be ordered from
KEB by the following material number:
Table 2.5.1

0090339-3361 3 x 33,0 µF
0090339-4751 3 x 4,7 µF
0090339-0860 3 x 8,0 µF
2.5.2 Preparations
If not be done before measurement the following steps are necessary:
•switch system de-energized
•secure against restart
•await one minute for discharge of the capacitors
• cleansine-wavelterfromdustandothercontaminations
2.5.3 Disassembly of the old capacitors
•remove heat-shrinkable tube with knife
•unscrew connection cable
• removexingbolts
•remove capacitor
•execute insulation test in accordance with 2.4.3 (if required)
2.5.4 Installation of new capacitors
•insert capacitor
• tightenxingboltinaccordancewithtable2.5.1
•pull heat-shrinkable tube over the connection cables
•tighten connection cable in accordance with table 2.5.1
•lock heat-shrinkable tube with hot-air fan
2.6 Disposal
The capacitors are lead-free and use M-DBT as dielectric. Disposal of old capacitors must
be done in accordance with the local regulations.
