User's Manual

This chapter describes external connections of the Thyro-P as well as all available terminal strips

and signals as necessary. Shielded cables grounded on the Thyro-P side must be used for the con-

nection of the control signals (setpoint inputs and analogue outputs). For the connections to RESET,

Controller lock and QUIT, twisted cables must be used.

Bus interfaces can be found in chapter 5 INTERFACES. To operate the Thyro-P at least the following

signals described up to chapter 4.5 QUIT must be connected.

4.1 POWER SUPPLY FOR THYRO-P

In the case of types 400V and 500V, connecting the regulator to the power supply also connects the

control device Thyro-P to the power supply (see also chapter POWER SUPPLY FOR THE CONTROL

DEVICE A70). The control device for 690V types must be supplied separately.

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 A7

The Thyristor Power Controller Thyro-P is ﬁ tted 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.

REMARK

If required, e.g. when operating with Proﬁ bus, 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.

CAUTION

The pulled plug has mains voltage of the load circuit! The new connecting lines must be fused

according to the applicable regulations (plug see chapter 12).

4.3 POWER SUPPLY FOR THE VENTILATOR

With Thyro-P Thyristor Power Controllers furnished with integrated ventilators (HF types), the venti-

lator must be supplied with a voltage of 230V 50/60Hz according to the connecting plans and the

dimensional drawings. The ventilator’s power consumption is given in chapter 10, Technical Data.
