• 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. Make sure to wait minimum 1 minute after switch-off (discharge
time of the attenuation capacitors). 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 qualifi ed and trained maintenance personnel.
CAUTION
Danger of electric shock. Even after disconnection from the mains
voltage, 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 Power Solutions GmbH.
