CAUTIONS...
1. The fans contained within this unit are not fitted with dust/insect filters. Pay attention to the
environment in which it is to be used.
2. Do not install units so that the air intakes of one align with the outlets on another. Provide baffles and
adequate spacing.
The Modulator 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 50 mm free air-space at each side of the equipment to
ensure adequate cooling. Units in racks can be stacked without the need
for ventilation panels between them. 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 equipment in areas of high humidity or where there is a
danger of water ingress.
Environment
The Modulator is intended to operate in ambient air temperature
conditions in the range 0
°
C to +50
°
C, and relative humidity 0% to 90%
(non-condensing). See Annex B, Technical Specification for a full
specification.
