4. External connections
4.1 Power supply for Thyro-A
Connecting the power supply is carried out as shown in the figures and technical
data. With Thyro-A 2A a right rotational field in the power circuit is required.
4.2 Power supply for the control device
The control device is supplied directly from the power section (terminals U1, X1.1
and X1.2). This voltage also serves as mains synchronization. The mains connection
is equipped for input voltages of U
Nnom
-15% to +10% and nominal frequencies
of 47Hz to 63Hz. Both terminals (X1.1 and X1.2 1.5mm
2
grid 3.81) are internally
bridged. If a phase is connected to X1, a fused connection is necessary
(figs. 3,7).

3.3 Diagnosis / status indications
Faults can occur in the load circuit and in the controller itself or from the mains.
Diagnosis of unexpected operating behaviour is performed by LEDs on the front
panel of the control device.
