1 Intended Use
The THYRO SWITCH is a power electronics component for connecting capacitive loads to the power
network. The device is intended exclusively for installation in switchgear and controlgear. Both non-reactor- and
reactor-protected (up to 14%) compensation stages can be switched. First and foremost, symmetrical three-phase
current compensation is intended as the application, but it is also possible to switch two separate alternating
current compensation stages simultaneously.

2 Safety Notes
Due to the design with forced cooling, that is with the use of a fan, unimpeded air intake must in particular be
guaranteed. The coolingopenings must not be coveredup. The distances specified from neighboring components
must be observed. For nominal load, there is an increase in temperature between fresh airand exhaust air of max.
40°C. Temperature-sensitive components such as cable ducts should be protected by cowls.
The THYRO SWITCH may only be operated with a series-connected power disconnecting device.
The THYRO SWITCH cannot function alone as a component and must be project-planned for use with a
compensation unit.
The THYRO SWITCH 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. In case of an error, the following cases 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 THYRO SWITCH may only be connected with insulated crimping cable lugs.
Work such as assembly, maintenance and servicing may only be performed by skilled electricians. A soon as the
THYRO SWITCH is connected to the power supply system, the capacitive load is charged to network peak
voltage. In addition a phase is connected 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, disconnection from the
network must be made under all circumstances. Danger to life!
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 isolated from the supply. 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 50µC at most, or a 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,
with the correct use of connectors, and these connectors can be pulled off without the use of tools, the discharge
must be complete within one minute (See EN 50178, Section 5.2.5).
For the design 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 facilities with conventional protective relaying and semiconductor technology is only
possible for reactor-protected equipment. Otherwise the THYRO SWITCH could be destroyed by the effects
of charge transfer.

3 Areas of Application
The THYRO SWITCH is intended in particular for facilities with frequent and rapidly changing reactive power
loads. The advantages of the THYRO SWITCH compared to conventional technology are:
• High switching speed
• Switching behavior with low system pollution
• Switching with no wearing parts
• Long working life through practically unlimited frequency of operations
Areas of application:
• Crane equipment
•Lifts
• Welding equipment
• Molding
• Wind turbines
The power switch can be operated in conjunction with VAr controllers, memory-programmable controls, computer
systems and process control units.

4 Installation
TheTHYRO SWITCH canbe installedhorizontallyorvertically.Due to theforcedcooling,nearlyallthewarm
air produced is emitted in one direction. At maximum load, a temperature increase of max. 40°C can be expected.
If temperature-sensitive components are used, such as cable ducts, it is possible that cowls must be provided.
Distances:
Fan side: >50mm
Heat sink outlet: >150mm
With vertical installation it must be ensured that warm air is always emitted upwards. When installing several
THYRO SWITCH on top of one another, cowls should be used.

For the connection of the load current with insulated crimping cable lugs with 8mm rings, terminal studs are
envisaged that must be tightened with a torque of 5.5 - 6Nm. The cable lugs must be exactly vertical to the
conducting plate. When laying leads, you should ensure that the connection leads are not heated up directly by
the exhaust from the heat sinks. As load fuses, fuse units for the protection of semiconductors must be used.
Project planning of their size must be made according to the connected capacitive load. You must ensure that the
equipment grounding conductor is connected correctly. The equipment grounding conductor connection in the
form of an M6 hexagon bolt is located on the heat sink beneath the connections for the capacitor and is labeled
with the PE conductor sign .
For reactor-protected equipment it is absolutely essential that the THYRO SWITCH is connected in series
before inductor and capacitor.
Terminal 1(+) and 3(-): For gating with 10-30V DC, terminal 1 must be connected to plus and
terminal 3 to minus.
(see design: DC gating on page 5)
Terminal 2 and 3: For gating with 180-260V AC 50/60Hz, terminals 2 and 3 must be used.
(see design: AC gating on page 5)
Terminal 4 and 5: The supply voltage 200-250V AC or 100-130V AC with 50 or 60Hz is connected
to terminals 4 and 5.
(see design: DC gating and AC gating on page 5)
6 Commissioning
1. Check the correct connections of the THYRO SWITCH
2. Attach plastic housing
3. Switch on supply voltage ("Power" LED lights up)
4. Possible test of gating by the controller ("Control" LED lights up and fan starts up)
Note: The operational current may only be released for the initial commissioning if
no gating takes place, that is, the THYRO SWITCH is switched off.
6. Connecting operational current
7. Release controller (for gating and correct function, "Power", "Control", "Thyr1" and "Thyr2" light up)
