Installation instructions
1.8 Installation instructions
1.8.1 Cooling systems
The KEB COMBIVERT F5/F6 is available for different cooling systems:
Heat sink with cooling fan (mounted version)
The standard version is delivered with heat sink and cooling fan.
Special versions
The dissipation of power loss must be guaranteed by the machine builder.
Flat rear
There is no heat sink at this version. The unit must be mounted on an appropriate ground for
heat dissipation.
Water cooling
This version is dimensioned for the connection to an available cooling system. The dissipa-
tion of the power loss must be ensured by the machine builder. In order to avoid moisture
condensation, the minimum inlet temperature may not decrease the ambient temperature.
The max. inlet temperature may not exceed 40°C. No aggressive coolant shall be used.
Measures against contamination and calcination must be done externally. We recommend a
pressure of 4 bar on the cooling system.
Convection (through-mount version)
In this version the heat sink is placed externally with a cutout in the control cabinet.
Warning Hot surface
Heat sinks can reach temperatures, which can cause burns when touching. If
in case of structural measures a direct contact cannot be avoided, a warning
notice "hot surface" must be mounted at the machine.

Safety and application notes
1. General
In operation, drive converter depending on their degree of
protection, may have live, uninsulated and possibly also
moving or rotating parts, as well as 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.
For further information, see documentation.
All operations serving transport, installation and commis-
sioning as well as maintenance are to be carried out by
skilled technical personnel (Observe IEC 364 or CENE-
LEC HD 384 or DIN VDE 0100 and IEC 664 or DIN/VDE
0110 and national accident prevention rules!).

strains. In particular, no components must be bent or iso-
lating distances altered in the course of transportation or
handling. No contact shall be made with electronic compo-
nents and contacts.
Drive converter contain electrostatic sensitive components
which are liable to damage through improper use. Electric
components must not be mechanically damaged or de-
stroyed (potential health risks).
5. Electrical connection
When working on live drive converter, the applicable na-
tional accident prevention rules (e.g. VBG 4) must be com-
plied with.
The electrical installation shall be carried out in accord-
ance with the relevant requirements (e.g. cross-sectional
areas of conductors, fusing, PE connection). For further
information, see documentation.
Instructions for the installation in accordance with EMC
requirements, like screening, earthing, location of lters
and wiring, are contained in the drive converter documen-
tation. They must always be complied with, also for drive
converter bearing a CE marking. Observance of the lim-
it values required by EMC law is the responsibility of the
manufacturer of the installation or machine.
6. Operation
Installations which include drive converter shall be
equipped with additional control and protective devices
in accordance with the relevant applicable safety require-
ments, e.g. act respecting technical equipment, accident
prevention rules etc.. Changes to the drive converter by
means of the operating software are admissible.
After disconnection of the drive converter from the voltage
supply, live appliance parts and power terminals must not
be touched immediately because of possibly energized
capacitors. In this respect, the corresponding signs and
markings on the drive converter must be observed.
During operation, all covers and doors shall be kept closed.

2.4.1 Mains input
TheKEBCOMBIVERTisdependentontheinputrectiersuitablefor3-phasemainssupply
(B6-rectier-circuit)or6-phase(B12-rectier-circuit).Thiscanberecognizedattheinputter-
minals (see picture „Mains input“ und „Mains input 3-phase“).
TheB12rectiercircuitisconnectedtotwo3-phasemainssupplyphase-shiftedby60de-
grees. This effects a reduction of the net reactions at high power. In spite of the electric
advantagesandincreasedlifetime,thisnetworkcongurationisnotoftenrealizedbecause
ofhightransformercosts.TheDClinkoftheCOMBIVERTwithB12rectiercircuitisdimen-
sioned by such way that connection to a 3-phase mains supply is also possible. The different
connection methods are described in chapter „Connection of the power unit“.
Info All terminal strips following the requirements of the EN 60947-7-1

General information to realize a 6-phase mains supply. The voltage of the two mains sup-
plies are electrically shifted by 60 degrees. The following transformers are used to realize
such mains supply.
One transformer with 2 secondary sys-
tems or
Two transformers with one system each
Transformer connection D d0 y11 Transformer connection Y yn0
Transformer connection Y d11
The primary star connection is selected at direct medium voltage supply. Transformer con-
nections D y0 and D d11 are also used at 690V or 400V supply.
