Maintenance
Periodically check that the protective grille
on the cooling fan on the back panel of the
RAM-XL amplifier is clear of blockages.
Clean gently with a vacuum cleaner if
necessary. Increased fan noise can be an
indication of increased heat load due to a
blockage. In an extreme case the amplifier
may automatically shut off.
Safety Considerations
Although this product has been designed
in accordance with international safety
standards, to ensure safe operation and to
maintain the monitor under safe operating
conditions, the following warnings and
precautions must be observed:
• Servicing and adjustment must only
be performed by a certified Genelec
service. The monitor enclosure or the
RAM-XL amplifier unit must not be
opened.
• Do not use this product with an
unearthed mains cable or a mains
connection without the protective earth
contact as this may lead to personal
injury.
• To prevent fire or electric shock, do not
expose any part of the product to water
or moisture.
• Do not place any objects filled with
liquid, such as vases on or near any
part of the product.
• The ”Woofer” and ”Midrange/Tweeter”
connectors on the RAM-XL amplifier
can output hazardously high voltages.
To ensure safety, the wiring connected
to these connectors must be installed
by a qualified and trained person.
• Note that the amplifier is not
completely disconnected from the AC
mains service unless the mains power
cord is removed from the amplifier or
the mains outlet. Easy access to either
end of the power cord must be ensured
at all times.
• Sufficient clearances and free flow
of air around the RAM-XL amplifier
as defined in chapters Amplifier
Positioning and Operating Environment
are necessary to maintain sufficient
cooling.
