AEG THYRO-A Operating Instructions Manual page 4

Operation
The Thyristor Power Controller may only be connected to the mains voltage if it has
been ensured that any hazard to people and system, especially in the load section,
has been eliminated.
• Protect the device from dust and moisture
• Do not block vents.
Maintenance, service, malfunctions
CAUTION
For maintenance and repair work the Power Controller must be
disconnected from all external voltage sources and protected against
restarting. The voltage-free state is to be determined by means of sui-
table measuring instruments. This work is only to be carried out by a
skilled electrician. The electrical regulations which are locally valid
are to be adhered to.
CAUTION
The Thyristor Power Controller contains dangerous voltages. Repairs
may only be carried out by qualified and trained maintenance per-
sonnel.
CAUTION
Danger of electric shocks. Even after disconnection from the mains
voltage, capacitors may still contain a dangerously high power
level.
CAUTION
Danger of electric shocks. Even when the Thyristor Power Controller is
not triggered, the load circuit is not disconnected from the mains.
ATTENTION
Different components in the power section are screwed into place
using exact torques. For safety reasons, power component repairs
must be performed by AEG SVS Power Supply Systems GmbH.
