4. External connections

4.1 Power supply for Thyro-S

Connecting the power supply is carried out as shown in the figures and TECHNICAL
DATA.

4.2 Power supply for the control device

The control device is supplied directly from the power section (terminals U1,
X1:1.2). This voltage also serves as mains synchronization. The mains connection is
equipped for input voltages of U -57% to +10% and nominal frequencies of
nom
47Hz to 63Hz. Both terminals (X1:1.2 1.5mm 2 grid 3.81) are internally bridged. If
a phase is connected to X1, a fused connection is necessary (figs. 3,7).

4.3 Digital set point input

The set point input is a logic input. Between the terminals X22:1 and 2 it can be
operated with a relay contact.
Between terminals X22:1 (signal), 3 (ground) it can be triggered with up to 24V d.c.
With input voltages Π3 Volt it recognises the signal ON.
The signal terminals can be connected with up to 1.5mm , in grid 3.5.
