5. COMMISSIONING

The Thyro-AX may only be started when there is absolutely no danger
to persons or system.
• Protect the device against dust and damp.
• Ensure that the ventilation openings are not blocked.

5.1 CONNECTIONS

The device has to be connected to the power supply and to further
external components or devices (PLC, Thyro-Power Manager or PC),
which are contingent to the application, in accordance with the connec-
tion diagrams.

5.1.1 GROUNDING

The grounding of the device shall be performed in accordance with the
local regulations (grounding screw/nut for connecting the protective
conductor to the heat sink). Grounding also serves for EMC means
(Y capacitor 4.7 nF + 12MΩ).

5.1.2 POWER SUPPLY AND LOAD

The connection of the power supply takes place in accordance with the
illustrations.
1. Switch off power supply and ensure it cannot be switched back on
again.
2. Ground the power controller.
3. Connect the load to the terminals (T1 + T3 in the case of the
Thyro-AX 2A, T1 + T2 + T3 in the case of 3A devices, or only T1 in
the case of the Thyro-AX 1A device)
4. Connect the terminals L1, L2 and L3 to the circuit breaker. In the case
of Thyro-AX 2A and 3A devices the connection must be made to a
clockwise rotating field in the power circuit.
5. Only in the case of Thyro-AX 1A and 2A devices: connect terminal
X1.1 to N or the other / middle phase. When connecting to a phase
a 2A slow acting fuse is required, at N the connection can be made
directly. The terminals (X1.1 and X1.2, 1.5mm2, grid 3.5) are bridged
internally.
6. Make any other necessary connections.
The input voltage is used simultaneously for mains synchronization.
Using flexible connection the terminals for the power can be used from
above or from below. Contacts with the same designation are connec-
ted with one another internally so that the connections can be divided
up to enable various combinations.
WARNING
HAZARDS DURING INSTALLATION
Danger of injury/damage to the device or system
- Take note of the labelling for the connections, as contacts with the
same designation are connected internally and if confused there is a
risk of a short-circuit occuring.

5.1.3 ELECTRONIC SUPPLY

The electronics of the control device is supplied by a separate con-
nection with 230V~ / 110V~ (85V - 265V 47Hz - 63Hz). The connection
2
is made at terminals X4.1 and X4.3 (1.5mm
and X4.2, along with X4.3 and X4.4 are internally bridged and offer an
alternative connection option.
The connection cables are to be fused in accordance with the appli-
cable regulations. An internal 2A fuse protects the device in the case of
internal short-circuits. In the case of Thyro-AX 2A and 3A each power
unit must be connected separately to the electronic supply, this is wired
up correspondingly at delivery.

5.1.4 FAN

Devices with a rated current from 230A and more require a power
supply of 230V~ for fan at terminal X7. Devices with a rated current of
30A and 100A come with a fan which is feed in by the device. In this
case no extra connection is required. The connection is wired up corres-
pondingly at delivery.

5.1.5 CONTROL SIGNALS

The control signals influence the functional mode of the device. Shielded
control cables must be used for the connection of the control signals.
The following control signals are required for the operation of the
device:
- Connect setpoint (setpoint 1 to X2.4 (signal) and X2.3 (ground) or
connect setpoint 2 to X2.11 (signal) and X2.3 (ground). Alternatively
via bus module or PC)
- Pulse inhibition (connect terminal X2.2 with ground X2.1)
If the pulse inhibition bridge is not connected then the device is
blocked and will not function. Communication via the interfaces
continues to be possible.
Please read carefully the information given in chapter 5.1.6. when using
the USB interface.
