2.3.3.1 Care in Positioning
Cautions!
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.
Do not install equipment 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.
2.3.3.2 Protection from Moisture
Do not install this equipment in areas of high humidity or where there is a danger of
water ingress.
