Safety instructions Safety and operating instructions Safety and operating instructions for drive converter (in accordance with: Low-Voltage Directive 2006/95/EC) 1. General Drive converter contain electrostatic sensitive components In operation, drive converter depending on their degree of which are liable to damage through improper use. Electric protection, may have live, uninsulated and possibly also components must not be mechanically damaged or de- moving or rotating parts, as well as hot surfaces.
This product can cause high frequency disturbances in residential areas (category C1) which require noise suppression measures. The specified value is only meet in connection with a corresponding filter. Depending on the operating conditions and corresponding power reduction, higher temperatures are permissible after consulting KEB. Above 2000 m there is no "safe isolation" of the control.

Connection Power Unit 2.8.1 Mains and motor connection 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.
Connection Power 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 •...
Temperature detection T1, T2 Parameter In.17 displays in high byte the installed temperature input of the inverter. If the KEB COMBIVERT F5/F6 is delivered as standard with switchable PTC/KTY evaluation, the required function Pn.72 (dr33 at F6) can be set and operates in accordance with the following table: In.17 Function of T1,...
Connection Power Unit 2.8.4.1 Use of the temperature input in KTY mode Connection of a KTY sensor KTY sensors are poled semiconductors and must be operated in forward direction! Connect anode to T1 ! Non-observance leads incorrect measurement in the upper temperature range.
Connection Power Unit 2.8.5 Connection of a braking resistor Braking resistors dissipate the produced energy of the motor into heat during generatoric operation. Thus braking resistors can cause very high surface tem- peratures. During assembly pay attention to appropriate protection against con- tact and fire.
Connection Power Unit 2.8.5.2 Braking resistor with over-heat protection and GTR7 monitoring This circuit offers a direct protection with defective GTR7 (braking transistor). At defective braking transistor an integrated relay opens the terminals K1/K2 and error „E.Pu“ is released. Terminals K1/K2 are integrated into the holding circuit of the input contactor, so the input volt- age is switched off in error case.
Connection Power Unit 2.8.5.3 Braking resistor with over-heat protection without GTR7 monitoring This circuit offers a direct protection with defective GTR7 (braking transistor). The braking resistor overheats and opens the OH terminals 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 Annex A Overload characteristic Time [s] Load [%] 105 110 115 120 125 130 135 140 145 150 160 170 180 190 200 210 220 The characteristic decreases depending on the overcurrent limit in this range (see unit identification). On exceeding a load of 105% the overload integrator starts.
Monthly Examine and clean extracted air filter and cooling air filter of the control cabi- net. Examine function of the fans of the KEB COMBIVERT. The fans must be re- placed in case of audible vibrations or squeak. Check the connecting ducts for corrosion and change it if necessary for units Annual with water cooling.
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.
B.1.2 UL Marking Acceptance according to UL is marked at KEB inverters with the adjacent logo on the type plate. To be conform according to UL for use on the North American and Canadian Market the fol- lowing additionally instructions must be observed (original text of the UL-File): •...

This has positive effects on lifetime-relevant components such as fan and DC link circuit capacitors and power modules (IGBT). Also the temperature dependent switching losses are positively effected. The use of water-cooled KEB COMBIVERT frequen- cy inverters is offered in the drive technology, because there are process-caused coolants available with some applications.

• Pay attention to flux direction and check tightness ! • The cooling flow must always be started before starting the KEB COMBIVERT. The connection to the cooling system can occur as closed or open cooling circuit. The con- nection to a closed cycle cooling circuit is recommended, because the danger of contamina- tion of coolant is very small.
