4. maintenance and servicing may only be performed by qualified electricians A soon as the thyroswitch is connected to the power supply system the capacitive load is charged to to network peak voltage In addition a phase is switched directly to the load This means that the load is under voltage even when switched off and remains connected to the power supply When working on the load the device must be disconnected from the power supply under all circumstances Risk of fatal injury 6 V2 0 EDEBDAO0200 2112 1 EN EDEBDAO0200 2112 1 EN thyro gy switch Even after disconnection from the network a residual charge remains in the capacitive load Before working on the equipment it must be checked that the capacitors are de energized The discharge time of the capacitors must be taken into account Note Power capacitors must be equipped with permanently connected discharge devices and be discharged within five minutes to a residual charge of max 50uC to a voltage of 60V If this has a disturbing effect on the function of the electrical equipment a warning sign must be put up in a clearly visible position stating that the discharge time is longer than five minutes If it is possible to come into contact with the voltage of the capacitors even if the connectors are used correctly and if these connectors can be pulled off without the use of tools the discharge must be possible within one minute See EN 50178 section 5 2 5 For the set

6. g thyro g switch 2 Safety note Due to the design with forced cooling i e with the use of a fan particularly the unimpeded air intake must be guaranteed The cooling openings must not be covered up The distances specified from neighboring components must be observed For rated load there is an increase in temperature between fresh air and exhaust air of max 52 C for type 115A max 40 C for type 90A max 35 C for type 70A Temperature sensitive components such as cable ducts should be protected accordingly The thyroswitch may only be operated with a power disconnecting device connected in series The thyroswitch cannot function alone as a component and must be configured for use with a compensation unit In detuned systems it is absolutely essential that the thyroswitch is switched before the inductor and capacitor The thyroswitch may only be deployed in the context of its intended use Even when used only as intended a defect cannot be ruled out In this case the currents and voltages in the load circuit could be affected The following errors are possible Current interruption half wave operation or constant energy flow Correct design of protective devices must therefore be ensured during project planning Incorrect operation or wrong connections could lead to destruction of the device or the load The thyroswitch may only be connected with insulated crimp type cable sockets Work such as assembly
7. lfill the requirements of the connected capacitive load It must be ensured that the grounding conductor is connected correctly The grounding conductor connection is an M6 hexagonal screw that can be found on the heat sink beneath the connections for the capacitor and is labeled with the grounding conductor sign In detuned systems it is absolutely essential that the thyroswitch is connected before the inductor and capacitor Terminals 1 and 3 For 10 30V DC input terminal 1 must be connected to plus and terminal 3 to minus Terminals 2 and 3 For 180 260V AC 50 60 Hz input terminals 2 and 3 must be used Terminals 4 and 5 The supply voltage 200 250V AC or 85 265V AC with 50 or 60Hz is connected to terminals 4 and 5 6 Start up 1 Make sure that the thyroswitch is properly connected 2 Attach the plastic housing 3 Switch on the supply voltage Power LED lights up 4 If necessary check the connection of the controller control LED lights up and fan starts up Note The load current may only be released for the first start up if there is no connection i e the thyroswitch is switched off 6 Connect the load current 7 Release the controller if connected and functioning correctly Power Control Thyr1 and Thyr2 light up 8 The fan can be switched on permanently with a jumper 10 V2 0 EDEBDAO0200 2112 1 EN EDEBDAO200 2112 1 EN thyro gy switch 7 Performance limitation depending on
8. up of the discharge equipment it must be remembered that capacitors when switched off are charged to a direct voltage at the level of the network peak voltage The parallel operation of systems with conventional protective relaying and semiconductor technology is only possible for induced systems Otherwise the thyroswitch could be destroyed by charging effects 3 Application range The thyroswitch is particularly intended for systems with frequent and rapidly changing reactive power loads The advantages of the thyroswitch compared to conventional technology are High switching speed Switching performance with low system perturbation Switching without wearing parts Long working life thanks to practically unlimited frequency of operations Fields of application Cranes e Lifts Welding equipment Molding presses Wind turbines The power switch can be operated in conjunction with reactive power controllers programmable logic controllers computer systems and process controllers V2 0 7 thyro g switch 4 Installation The thyroswitch should be installed vertically or max 45 tilted The integrated fan controls the air flow so that nearly all the warm air produced is emitted in one direction Temperature sensitive components installed near the device have to be protected accordingly The safe distances specified must be observed Fan side 550mm Heat sink outlet 150mm If the device is installed
