1.4 Installation instructions
1.4.1 Cooling systems
The KEB COMBIVERT F5 is available for di󰘯erent 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.
• Watercooling
This version is dimensioned for the connection to an available cooling system. The dissipation 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.
Max. pressure on the cooling system may not exceed 4 bar (special versions with higher pressures possible on
request).
• Convection(through-mountversion)
In this version the heat sink is placed externally with a cutout in the control cabinet.
CAUTION
!
DO NOT TOUCH!
Hot Surfaces
© 2005 KEB
In case of burn, cool inflicted area
immediately and seek medical attention.
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 sur-
face" must be mounted at the machine.
1.4.2 Safety relay for „safety stop in accordance with EN954-1/ category 3“
With the function "safety stop" one of the following conditions must be ful󰘰lled:
• the power supply to the drive must be interrupted (double security)
• no torque at the drive
The KEB COMBIVERT F5 with safety relay ful󰘰lls the condition: no torque by a safe disconnection of the driver
signals for the power modules (IGBT). There is no voltage disconnection.
This is guaranteed by a two-channel processing holding signal. On of the channels is developed in programmed
electronics. The second channel consists of an electro-mechanical relay. The function of the relay is cyclically
monitored by the programmed electronics.
Through the double safety no further measure is needed for the KEB COMBIVERT (e.g. feedback
relay contact) since an individual error in the control does not lead to the loss of the stop function.

1.5 Installation of water-cooled units
In continuous operation water-cooled inverters are operated with lower temperature than air-cooled inverters. This
has positive e󰘯ects on lifetime-relevant components such as fan and DC link circuit capacitors and power mo-
dules (IGBT). Also the temperature dependent switching losses are positively e󰘯ected. The use of water-cooled
KEB COMBIVERT frequency inverters is o󰘯ered in the drive technology, because there are process-caused
coolants available with some applications. The following instructions must be observed absolutely when this units
are used.
1.5.1 Heat sink and operating pressure
Design system Material (voltage) Max. operating pressure Connecting duct
Extrusion casting heat sink Aluminium (-1.67 V) 10 bar 00.00.650-G140
The heat sinks are sealed with sealing rings and have also a surface protection (anodized) in the ducts. The heat
sinks are generally maintenance-free!
In order to avoid a deformation of the heat sink and the damages involved, the indicated max. opera-
ting pressure may not be exceeded brie󰘱y also by pressure peaks.
Pay attention to the guidelines 97/23/EG of pressure units.
1.5.2 Materials in the cooling cicuit
For the screw connections and also for the metallic articles in the cooling circuit which are in contact with the
coolant (electrolyte) a material is to be selected, which forms a small voltage di󰘯erence to the heat sink in order
to avoid contact corrosion and/or pitting corrosion (electro-chemical voltage series, see table 1.5.2). An aluminum
screw connection or ZnNi coated steel screw connection is recommended. Other materials must be examined in
each case before employment. The speci󰘰c case of application must be checked by the customer in tuning of the
complete cooling circuit and must be classi󰘰ed according to the used materials. With hoses and seals take care
that halogen-free materials are used.
A liability for occuring damages in case of wrong used materials and from this resulting corrosion cannot be as-
sumed!

General
1.5.3 Requirements on the coolant
The requirements on the coolant are depending on the ambient conditions, as well as from the used cooling sy-
stem. General requirements on the coolant:
Standards TrinkwV 2001, DIN EN 12502 part 1-5, DIN 50930 part 6, DVGW work sheet W216
VGB
Cooling water directive
The VGB cooling water directive (VGB-R 455 P) contains instructions about common
process technology of the cooling. Particulary the interactions between cooling water
and components of the cooling system are described.
pH-value Aluminum is particularly corroded by lixiviums and salts. The optimal pH value for
aluminum should be in the range of 7,5… 8.0.
Abrasive substances Abrasive substances as used in abrasive (quartz sand), clogging the cooling circuit.
Copper cuttings Copper cuttings can attach the aluminum and this leads to a galvanic corrosion. Cop-
per should not be used together with aluminum due to electro-chemical voltage di󰘯e-
rence.
Hard water Cooling water may not cause scale deposits or loose excretions. It shall have a low
total hardness (<20°d) especially carbon hardness.
Soft water Soft water (<7°dH) corrodes the material.
Frost protection An appropriate antifreeze must be used for applications when the heat sink or the
coolant is exposed temperatures below zero. Use only products of one manufacturer
for a better compatibility with other additives.
Corrosion protection Additives can be used as corrosion protection. In connection with frost protection the
antifreeze must have a concentration of 20…25 Vol %, in order to avoid a change of
the additives.
Special requirements for open and half-open cooling systems:
Impurities Mechanical impurities in half-open cooling systems can be counteracted when appro-
priate water 󰘰lters are used.
Salt concentration The salt content can increase through evaporation at half-open systems. Thus the
water is more corrosive. Adding of fresh water and removing of process water works
against.
Algae and myxobacte-
ria
Algae and myxobacteria can arise caused by increased water temperature and contact
with atmospheric oxygen. The algae and myxobacteria clog the 󰘰lters and obstruct the
water-󰘱ow. Biocide containing additives can avoid this. Especially at longer o󰘯 periods
of the cooling circuit preventive maintenance is necessary.
Organic materials The contamination with organic materials must be kept as small as possible, because
separate slime can be caused by this
Damages at the unit which are caused by clogged, corroded heat sinks or other obvious operating er-
rors, leads to the loss of the warranty claims.
1.5.4 Connection to the cooling system
•Screw in connecting duct in accordance with the manual
• The connection to the coolant must be carried out with 󰘱exible, pressure-resistant hoses and secured with
clamps.
• Pay attention to 󰘱ux direction and check tightness !
• The cooling 󰘱ow must always be started before starting the KEB COMBIVERT.
The connection to the cooling system can occur as closed or open cooling circuit. The connection to a closed
cooling circuit is recommended, because the danger of contamination of coolant is very small. Preferably also a
monitoring of the pH value of the coolant should be installed.
Pay attention to a corresponding cable cross section at required equipotential bonding in order to avoid electro-

General
chemical procedures.
1.5.5 Coolant temperature and moisture condensation
The inlet temperature may not exceed 40°C. The maximum heat sink temperature is 60 °C or 90 °C depending on
the power unit and overload capacity (see „technical data“). To ensure a safe operation the coolant output tempe-
rature must be 10 K below this temperature.
Due to high air humidity and high temperatures it can lead to moisture condensation. Moisture condensation is
dangerous for the inverter, because the inverter can be destroyed through eventual occuring short-circuits.
The user must guarantee that any moisture condensation is avoided!
In order to avoid a moisture condensation the following possibilities can be done. The application of both methods
is recommended.
Supply of temper coolant
This is possible by using heatings in the cooling circuit for the control of the coolant temperature. The following
dew point table is available for this:

Temperature Control
The cooling system can be connected by means of pneumatic or magnetic valves. A relay is frontend. In order to
avoid pressure surges, the valves for the temperature control must be inserted before the cooling circuit. All usual
valves can be used. Pay attention that the valves are faultless and do not clamp.
During transport or storage below the freezing point, the heat sink must be completely drained with air
pressure.

Connection Terminals
2.4 Terminal strips of the power circuit
All terminal strips following the requirements of the EN 60947-7-1 (IEC 60947-7-1)
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 terminals (see picture 2.4.1.a and 2.4.1.b).
The B12 rectier circuit is connected to two 3-phase mains supply phase-shifted by 60 degrees. This effects a
reduction of the net reactions at high power. In spite of the electric advantages and increased lifetime, this net-
work conguration is not often realized because of high transformer costs. The DC link of the COMBIVERT with
B12 rectier circuit is dimensioned 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“.
General information to realize a 6-phase mains supply. The voltage of the two mains supplies
are electrically shifted by 60 degrees. The following transformers are used to realize such mains
supply.
One transformer with 2 secondary systems
or
Two transformers with one system each
Transformer connection D d0 yn11 Transformer connection Y yn0
Transformer connection Y d11
The primary star connection is selected at direct medium voltage supply. Transformer connections D y0 and D
d11 are also used at 690V or 400V supply.
