Installing the Equipment
2.3.1
Fixing
The TT1220 is designed for fixed use only and has been shipped with fixing
brackets suitable for a standard 19 inch rack. When installed in a rack, it
should be secured by using the fixing brackets. In addition, support
shelves must be used to reduce the weight on the brackets. Ensure it is
firmly and safely located and it has an adequate free-flow of air.
A free-standing unit should be installed on a secure horizontal surface
where it is unlikely to be knocked or its connectors and leads disturbed.
2.3.2
Ventilation
Openings in the Covers
Openings in the cabinet are provided for ventilation. These ensure reliable
operation of the unit and protect it from overheating. These openings must
not be blocked or covered.

CAUTIONS…
1.
The fan and openings contained within this unit are not fitted with a dust / insect filter. Pay
attention to the environment in which it is to be used.
2.
Do not install units so that the air intake for one unit aligns with the outlet of another. Provide
baffles and adequate spacing.
The TT1220 should never be placed near or over a radiator or other source
of heat. It should not be placed in a built-in installation such as a rack
unless proper ventilation is provided and the instructions have been
adhered to.
Allow at least 40 mm free air space at each side of the equipment to
ensure adequate cooling. Unit in racks can be stacked with no space in
between. Racks containing stacked equipment may need to be forced-air
cooled to reduce the ambient temperature within the rack.
Protection From Moisture
Do not install this unit in areas of high humidity or where there is a danger
of water or moisture entering the equipment.
