Installation Requirements
1. Environmental Conditions at Intended Installation Site
The unit may be installed in any location suitable for electronic communication
equipment, provided that the environmental conditions do not exceed the equipment
specifications for temperature, humidity and air quality.
 Operating Temperature
-30℃ to +60℃
This is the temperature measured in close proximity to the unit. For example, if the
unit is mounted in a cabinet, the tem perature within the cabinet is measured.
 Humidity
Humidity conditions should not exceed 95% relative humidity @ 50°C.
 Air Quality
For equipment operating in an area which is environmentally controlled and with the
unit rack mounted, the airborne particle level must not exceed 25μg/m
3
.
And for equipment operating in an area which is not environmentally controlled and with
the unit cabinet mounted, the airborne particle level must not exceed 90μg/m
3
.
Caution: If the unit is to be installed in an area which is usually dusty, dirty, or
does not meet the air quality requirements, then the air used to cool the unit modules
must be treated using appropriate filtering devices. Dust or dirt accumulated on the
internal circuit boards and modules is not easily removed, and can cause malfunctions
such as overheating and intermittent electrical connections.
2. Equipment Ventilation
The PA heatsink is equipped with a cooling fan used to provide forced convection cooling.
When planning the installation, observe the following ventilation guidelines:
 Customer supplied cabinets must be equipped with ventilation slots or openings for
