Should
the SI1287 be required
to operate in a hostile environment
then it should
be mounted in a protective
enclosure.
The
instrument
should always be operated
within
the limits of temperature,
humidity and vibration stated in
the
SI1287
Specification. See Appendix
C,
Note that the instrument
is not proof against corrosive atmospheres
or liquids.
5 RACK
MOUNTING
The
instrument can be rack
mounted in two ways: either
by using fixed rails in
the rack to support
the underside of
the case, or by using telescopic slides
to
support
the SI 1287 and allow
easy withdrawal for servicing.
With either
method, the pair of rack
mounting ears is substituted for the finisher
trims on the S11287; screws
inserted through the ears
and into the rack keep the
unit in place.
Note 1: The rack mounting
ears must be used only to prevent
the SI1287 sliding
out of the rack. They
are not designed
to support the whole weight of the
instrument.
Note 2:
If the SI1287
is
rack
mounted on telescopic slides, ensure
that the rack
will
not tip over when the
slides are
fully
extended.
5.1 RACK DIMENSIONS
The
internal
rack dimensions
required for fitting
the
SI 1287
are :
610mm (24ins) deep x
485rnm. (19ins) wide for fixed rail mounting,
and
760mm (30ins)
deep
x
485mm
(19ins)
wide for
telescopic slide mounting.
5.2 RACK
VENTILATION
The instrument has
fan-assisted ventilation.
Air is
drawn in
through slots in the
front panel
and exhausted
through a vent in the rear. To ensure that the instrument
always
runs cool,
keep the air inlet and outlet
clear. Leave a gap of at least 4
inches
(100mm) between the rear
panel and any vertical obstruction such
as a
wall. When
the instrument
is rack-mounted the rack itself
should also be well
ventilated.
