Operating instructions

3
The Thyristor Power Controller may only be operated in the sense of its intended
use; otherwise personal hazards, for (e.g. electric shocks, burns) and hazards for
systems (e.g. system overload) may arise.
Residual hazards of the product
• Even in case of proper use, should a fault occur, it is possible that control of cur-
rents, voltages and power is no longer performed in the load circuit by the
Thyristor Power Controller.
In case of destruction of the power components (e.g. break-down or high resi-
stance), the following situations are possible: power interruption, half-wave opera-
tion, continuous power flow. If such a situation occurs, then load voltages and cur-
rents are produced from the physical dimensions of the overall power circuit. It must
be ensured by system design that no uncontrolled large currents, voltages or power
occur.
Maloperation and the results
• With maloperation it is possible that power, voltage or flow levels which are
higher than planned reach the Thyristor Power Controller or load. On principle,
this can lead to the Power Controller or load being damaged.
Transport
• Thyristor Power Controllers are only to be transported in their original packaging
(protection against damage e.g. due to jolting, knocking, soiling).
Installation
• If the Thyristor Power Controller is brought into the operation room from a cold
environment, moisture can occur. Prior to it being commissioned, the Thyristor
Power Controller must be absolutely dry. Therefore, wait for a minimum of two
hours before commissioning.
Connection
• Prior to connection, it must be ensured that the voltage information on the type
plate corresponds with the mains voltage.
• The electrical connection is carried out at the designated points with the required
cross section and the appropriate screw cross sections.
