Operating environment
This appliance is designed to operate in most normal climates,
at a temperature between 0 °C and 50 °C (32 - 122 °F), with
relative humidity between 10% and 60%.
Power requirements
BEFORE you connect any unit to the mains, please make sure
that the voltage of your local AC supply is within the acceptable
range of the unit.
The Hera is designed to work from an AC supply between
90V and 240 V, at a frequency between 50 and 60 Hz. 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. Ensure that the unit has been
allowed to reach ambient temperature before switching it on.
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 ight-case or in an equipment rack, x
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 each side of the unit for suf-
cient ventilation.
