Safety precautions

Speaker system damage and protection of human beings
Power amps provide extremely high power output that might be dangerous for human beings
as well as for the connected speaker systems. High output voltages can damage or even
destroy the connected speaker systems, especially, when the amplifier is operated in bridged
mode. Prior to connecting any loudspeakers, make sure to check the speaker system's
specifications for continuous and peak power handling capacities. Even if amplification has
been reduced through lowering the input level controls on the amplifier's front panel, it is still
possible to achieve full power output with a sufficiently high input signal.
Danger!
Danger at the loudspeaker/power outputs
Power amplifiers are capable of producing dangerously high voltage output that is present at
the output connectors.
To protect yourself from electric shock, do not touch any blank speaker cables during
operation of the power amp.
Danger!
The terminals marked with a lightning bolt are hazardous live and the external wiring
connected to these terminals requires installation by an instructed person or the use of ready-
made leads of cords.
Danger!
In case of using the amplifier with speakers including a primary tapped transformer, it is
possible that during operation shock hazard voltages may be present at the taps of the
transformer.
Therefore, the taps have to be insulated sufficiently in accordance with applicable safety
regulations.
Bosch Sicherheitssysteme GmbH
The device must be free of any voltage before performing any alterations with upgrade
sets, switching the mains voltage, or performing any other modifications.
The minimum distance between voltage-carrying parts and metal parts that can be
touched (such as the metal housing) or between mains poles is 3 mm, and must be
observed at all times.
The minimum distance between voltage-carrying parts and circuit parts that are not
connected to the mains (secondary) is 6 mm, and must be observed at all times.
Special components that are marked with the safety symbol in the circuit diagram (note)
must only be replaced with original parts.
Unauthorized changes to the circuitry are prohibited.
The protective measures issued by the relevant trade organizations and applicable at the
place of repair must be observed. This includes the properties and configuration of the
workplace.
Observe the guidelines with respect to handling MOS components.
