Operating environment
This appliance is designed to operate in moderate climates at
a temperature between 5 and 40°C (41 - 104°F) with relative
humidity no more than 60 %.
Should the unit be installed in an equipment rack, it is important
to ensure that the operating temperature inside the rack does
not exceed the upper limit. This could be the case where the
rack contains power amplifiers. A cooling fan may be necessary
in such installations.
Before you get started
Power requirements
BEFORE you connect any unit to the mains, please make
sure that your local AC supply is within the range of voltages
required by the unit.
The dBZ-48d is designed to work from an AC supply between
100 V and 240 V, at a frequency between 50 and 60Hz. No AC
voltage selector is provided as the device automatically adjusts
to the incoming AC voltage.
Precautions should be taken so that the appliance is properly
grounded at all times. This unit must be earthed.
Installation
If the unit is brought into a warm room from a cold environment,
internal condensation may occur. Wait an hour or two before
switching it on so that it can reach the ambient temperature.
Although this unit is intended for installation in a standard
19-inch rack it can nevertheless be used freestanding. If the
unit is installed in a flight-case or in an equipment rack, fix
the unit with all four screws through the front panel holes. For
normal use no extra support is needed, but in more extreme
conditions, such as on the road, we recommend the unit is
supported at the rear.
Allow at least 10 cm (4 inches) at the back, front and sides of
the unit for sufficient ventilation.
