THE SAFETY INSTRUCTIONS AND OPERATING MANUAL ARE TO BE CAREFULLY READ PRIOR
TO INSTALLATION AND COMMISSIONING.
OBLIGATION TO GIVE INSTRUCTIONS
The following safety and operating instructions must be carefully read before assembly, installation
and commissioning of Thyro-P by those persons working with or on Thyro-P.
These operating instructions are part of the Power Controller Thyro-P.
The operator of this device is obliged to provide these operating instructions to all persons
transporting, commissioning, maintaining or performing other work on the Thyro-P without any
restrictions.
In accordance with the Product Liability Act, the manufacturer of a product has an obligation to
provide explanations and warnings as regards:
• the use of the product other than for the intended use,
• the residual product risk and
• operating error and its consequences.
The information given below must be understood in this respect. It is to warn the product
user and protect him and his systems.
PROPER USE
• The Thyristor Power Controller is a component which may only be used for control and regulation
of electrical energy in industrial alternating current or 3-phase networks.
• The Thyristor Power Controller may at maximum be operated using the maximum admissible
connected load according to information on the type plate.
• The Thyristor Power Controller may only be operated in connection with a suitable and series
connected power supply disconnecting device.
• As a component the Thyristor Power Controller is unable to operate alone and must be projected
for its intended use to minimize residual risks.
• The Thyristor Power Controller may only be operated in the sense of its intended use; otherwise,
personal hazards (for instance electrical shock, burns) and hazards for systems (for instance over-
load) may be caused.
RESIDUAL HAZARDS OF THE PRODUCT
• Even in case of proper use, in case of fault, it is possible that control of currents, voltages and
power is no longer performed in the load circuit by the Thyristor Power Controller.
In case of destruction of the power components (for instance breakdown or high resistance), the
following situations are possible: power interruption, half-wave operation, continuous power fl ow.
If such a situation occurs, then load voltages and currents are produced from the physical dimen-
sions of the overall power circuit. It must be ensured by system design that no uncontrolled large
currents, voltages or power results. It is not possible to totally exclude that during operation of
Thyristor power controllers other loads show abnormal behaviour. The physically determined
network reactions, depending on the operating mode, must be considered.
DANGER OF ELECTRIC SHOCKS
Even if the Thyristor Power Controller is not triggered, the load circuit is not disconnected from the
mains.
It is possible to safely disconnect the Thyristor Power Controller as under IEC 60950
