6.1. Rack mounting and cooling
Rack mounting
The 10D and 30D amplifier enclosures are designed to fit
standard 19" equipment racks or cabinets.
When specifying a rack, be sure to allow extra depth (150 mm /
6" is usually sufficient) to accommodate the cables and connectors
at the rear of the amplifier.
When mounting 10D/30D amplifiers into a 19" rack or equipment
cabinet, do not just rely on fixing and supporting the amplifiers by
their front panels using appropriate rack mounting screws and U
washers as shown in the graphic opposite. Provide additional
support ...
▪ by fixing the rear-mounted rack ears using appropriate rack
mounting screws and U washers as shown in the graphic
opposite.
▪ or using shelves fixed to the inner sides of the cabinet or rack.
Cooling
Thermal conditions are a vital factor to ensure operational safety of
the power amplifiers. The 10D and 30D amplifiers are equipped
with two internal fans that draw cool air from the front into the
housing and channel the warm air towards the back of the device.
▪ Please ensure that adequate cool airflow is provided.
▪ Do not block or cover the front panel air intake or the vents on
the rear panel.
▪ If amplifiers are installed in sealed cabinets (e.g. in fixed
installations), use additional fan modules with filters that can be
easily replaced without opening the sealed cabinets.
▪ Do not combine 10D/30D amplifiers with D6 or D12 amplifiers
in one rack.
▪ Do not rack up 10D/30D amplifiers together with other devices
producing additional heat with opposing airflows.
