AEG THYRO-S Series Operating Instructions Manual page 5

Operation
• The Thyristor switch 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 Thyristor switch must be discon-
nected from all external voltage sources and protected against restar-
ting. The voltage-free state is to be determined by means of suitable
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 switch contains dangerous voltages. Repairs may only
be carried out by qualified and trained maintenance personnel.
CAUTION
Danger of electric shock. Even after disconnection from the mains vol-
tage, capacitators may still contain a dangerously high power level.
CAUTION
Danger of electric shocks. Even when the Thyristor switch is not trigge-
red, 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.
