Appendix B: Safety Guidelines

At all times, the amplifier has to be operated under appropriate condi-
tions. This includes choosing an operation location that provides sufficient
ventilation and that the device is not exposed to direct sunlight including
the direct radiation or reflection from any heat source. When installing the
loudspeaker systems choose a location that does not transmit extreme
and/or constant vibration or other mechanical oscillation.
Do not take the risk of electro-shock or shock hazard. To reduce the risk
of electro-shock, all connections have to be accomplished before it is
permissible to connect the amplifier to the main supply. Verify that all
external connections are complete and that no short-circuits exist in any
of the wiring. The overall sound reinforcement installation has to be in
accordance to the laws, regulations, standards, and guidelines that are
relevant and applicable in the country/locality where the equipment is
going to be operated.

AC Power Supply

This equipment operates from a power source that does not apply more
than 244 VAC between the supply conductors or between either supply
conductor and ground.

DC Power Supply

A 24V DC power source (i.e. a battery) has to be connected to the
terminals (13) that are covered by a protective lid. To reduce the risk of
dropping voltage to a minimum and to eliminate the danger of damaging
the battery cables by thermal overload, these cables have to be at least
2.5mm in diameter, each Switching the amplifier on or off is performed
through the power switch (6).

Safety Precautions

1. Please read the notes proceeded by the symbol with special
attention, as they provide important safety information.
2. The power supply voltage of the amplifier has a sufficiently high
value to involve the risk of electrical shock; therefore, never
install, connect, or disconnect the equipment with the power
supply switched on.
3. The metal parts of the equipment are earthed by means of the
power cable. If the power socket used to supply power does not
have an earth connection, call a qualified electrician who will
earth the equipment by means of the terminal.
