Preface Preface The described hard and software are developments of the KEB Automation KG. The en- closed documents correspond to conditions valid at printing. Misprint, mistakes and technical changes reserved. Information on special measures The used pictograms have following significance:...
KEB Automation KG agency. Copyright The customer may use the instruction manual as well as further documents or parts from it for internal purposes. Copyrights are with KEB and remain valid in its entirety.
The used semiconductors and components of KEB Automation KG are developed and di- mensioned for the use in industrial products. If the KEB COMBIVERT F5 is used in machines, which work under exceptional conditions or if essential functions, life-supporting measures or an extraordinary safety step must be fulfilled, the necessary reliability and security must be ensured by the machine builder.
Installation instructions 1.8.1 Cooling systems The KEB COMBIVERT F5 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.

Safety and application notes Safety and application notes Safety and operating instructions for drive converter (in accordance with: Low-Voltage Directive 2006/95/EC) 4. Installation 1. General The devices must be installed and cooled according to the In operation, drive converter depending on their degree of regulations in the corresponding documentation.
The specified value is only meet in connection with a corresponding filter. Depending on the conditions and the appropriate derating higher temperatures can also be run in consultation with KEB. There is no "Safe isolation" of the control above 2000 m.
(xxF5Cxx-xxxx). This devices are not subject to export authorisation. Info Note pole pairs The technical data are for 2/4-pole standard motors. With other pole numbers the inverter must be dimensioned onto the motor rated current. Contact KEB for special or medium frequency motors.

Terminal strips of the power circuit Caution Observe input voltage, since 230 V and 400 V class possible All terminal strips meet the requirements according to EN 60947-7-1 Info (IEC 60947-7-1) Name Function Cable cross-sections Terminals No. L1, N 1-phase mains connection L1, L2, L3 3-phase mains connection U, V, W Motor connection...
Caution Incorrect connection possible! • Absolutely pay attention to the supply voltage of the KEB COMBIVERT. A 230 V unit at 400 V mains is destroyed immediately. • Exchanging mains and motor connection leads to immediate destruction of the unit.

2.8.2 Selection of the motor cable The correct selection and wiring of the motor cable is very important: • lower abrasion of the motor bearings by leakage currents • improved EMC characteristics • lower symmetrical operating capacities • less losses by transient currents 2.8.3 Connection of the motor As standard the connection of the motor must be carried out in accordance with the following table:...
2.8.5 Connection of a braking resistor Warning Very high surface temperatures Braking resistors dissipate the produced energy of the motor into heat during generatoric operation. Thus braking resistors can cause very high surface temperatures. During assem- bly pay attention to appropriate protection against contact and fire. Info Regenerative unit The use of a regenerative unit is reasonable for applications which produce a lot of regener-...
2.8.5.2 Braking resistor with overheat protection This circuit offers a direct protection with defective braking transistor (GTR7). The braking resistor overheats and opens the terminals OH1 and OH2 with defective GTR7. The OH terminals open the holding circuit of the input contactor, so that the input voltage is switched off in error case.
Annex A Annex A Overload characteristic Time [s] Load [%] 105 110 115 120 125 130 135 140 145 150 160 170 180 190 200 210 220 In this range the characteristic declines dependent on the overcurrent limit (see unit identification). Figure 15: Overload characteristic On exceeding a load of 105% the overload integrator starts.
A.4.2 Storage The DC link of the KEB COMBIVERT is equipped with electrolytic capacitors. If the electrolyt- ic aluminium capacitors are stored de-energized, the internal oxide layer is removed slowly. Due to the leakage current the oxide layer is unrenewed. If the capacitor starts running with rated voltage there is a high leakage current which can destroy the capacitor.
Storage period > 3 years • Input voltages as before, however double the times per year. Eventually change capac- itors. After expiration of this start-up the KEB COMBIVERT can be operated on nominal rating con- ditions or delivered to a new storage. A.4.3 Cooling circuit The cooling circuit must be completely empty if a unit shall be switched off for a longer period.
