This chapter describes external connections of Thyro-P as well as all available terminal strips and
signals as necessary. The connections of the interfaces
• X10 RS232 (optional with Bluetooth adapter or LBA-2)
• X30 Fiber optic receiver
• X31 Fiber optic sender
• X20 Bus interfaces
• X40 dASM input
• X41 dASM output
are described in chapter 5.
Shielded cables grounded on Thyro-P must be used for the connections of control signals (set point
inputs and analogue outputs).
For the connections to RESET, controller inhibit and QUIT, twisted cables must be used.
Bus interfaces can be found in chapter 5 INTERFACES.
To operate Thyro-P at least the following signals described up to chapter 4.6 QUIT must be connec-
ted.
4.1 POWER SUPPLY FOR THYRO-P
Details on connecting power supply can be taken from the chapters TECHNICAL DATA and CON-
NECTING DIAGRAMS. This particularly applies when using the control device in UL applications.
4.2 POWER SUPPLY FOR THE CONTROL DEVICE A70
The Thyristor Power Controller Thyro-P is fitted with a wide-band power supply. The mains connec-
tion is designed for input voltages from 230V -20% to 500V +10% and nominal frequencies from
45Hz to 65Hz. The power consumption is max. 30W. Depending on the switch mode power supply,
a 100VA control transformer must be used.
For the type ranges 400V (230-400V) and 500V nominal mains voltage, the control device is sup-
plied directly from the power section. It is therefore a unit ready to connect.
If the power controller is connected to the power supply, for types ranges 230-400V and 500V the
control unit of Thyro-P is therefore already connected to current supply. 1- and 2-phase Thyro-P
units need on A1-X1.3 an additional wiring in accordance to the connecting diagram (chapter 8).
The control device of 690V types has to be feed separately.

If required, e.g. when operating with Profibus, the control device can also be supplied separately.
With supply voltages outside the nominal range the control device must be supplied separately
with an input voltage within the above-mentioned voltage range. The phase position of this control
voltage is optional. In this case the plug (A70/X1) must be pulled.
