Cautions and Warnings
General
Thyristor modules TSM series may only be used for the purpose they have been designed for.
Thyristor modules TSM series may only be used in combination with appropriate pre-switched grid
separator device.
Thyristor modules have to be projected in such a way that in case of any failure no uncontrolled
high current and voltages may occur.
The devices in operation have to be protected against moisture and dust, sufficient cooling has to
be assured.
The connection is made via three phases according to picture 1. Take care for a correct phase
sequence! (If the phase-sequence is not correct, the module will be blocked.)
Activation of the modules is done by a 10 ... 24 V DC signal (by a dynamic reactive power
regulator) which is connected to terminals X3:1 and 2.
For cascading of several modules (for increase of the kVar-output) parallel-connection is possible.
For additional modules, programming of delay time is possible.
The power capacitors are permanently under high voltage (up to 1500 V DC) EVEN IF THE TSM-AT
IS SWITCHED OFF!!
Please follow the instructions:
Due to the switching principle of the thyristor module the power capacitors are permanently loaded to
the peak value of the grid voltage (DC voltage) even when switched off. Therefore following rules
have to be obeyed in any case:
Due to the high voltage (2 x peak value of nominal voltage) that occurs, the discharge resistors of
the power capacitors have to be replaced by special types.
In dynamic systems with TSM modules no fast discharge reactors may be used (reactor would
cause a DC voltage short circuit).
For applications without filter circuit reactors three current limiting reactors are mandatory per
thyristor module.
Thyristor modules in general have to be protected by accordingly dimensioned superfast
electronic fuses.
Those fuses have to be marked in the installation.
Due to the special switching, the PFC capacitors are fully loaded even when the particular step
has been switched off. Protection against contact has to be guaranteed. Warning signals in the
systems are required.
Even in switched off state no electrical isolation is achieved for electronic switches. Therefore
parts of the systems may not be touched after switching off the complete system before the
capacitors have been completely discharged.
Do not touch live parts in the PFC equipment!
Warning signs in the equipment required!
Wait 10 minutes after the main switch is turned off until the voltage in the system is down to an
uncritical value.
