Installing the Equipment

ST.RE.E10228.1
2.3 Installing the Equipment
2.3.1 Fixing
The equipment 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 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 flow of free-air.
Slide the receiver onto the chassis supports and affix to the rack by means of an M6 x 18 mm
panhead screw in each corner.
A freestanding 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
Side openings in the unit, as well as side-mounted cooling fans, are provided for ventilation. They
ensure reliable operation of the product and protect it from overheating. The openings of the fans
must not be blocked or covered.

CAUTIONS...
1. The fans 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 of one aligns with the outlet on another. Provide baffles and
adequate spacing.
The equipment 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.
Racks containing stacked equipment may need to be forced air-cooled to reduce the ambient
temperature within the rack.

Do not install this equipment in areas of high humidity or where there is a danger of water
ingress.
