Safety and Pre-Installation Requirements
Environmental Requirements
Tekelec products are designed for environments that have temperature and
humidity controls.Temperature and humidity controls must be activated as
quickly as possible for equipment to operate at an optimum level.
When temperature and humidity controls fail, the equipment has been tested to
operate within the following ranges:
• Temperature
— 5° C to 40° C (41° F to 104° F) for normal operation
— -5° C to 50° C (23° F to 122° F) for no more than 96 hours in duration and at
elevations less than 1800 meters
— -5° C to 50° C (23° F to 122° F) for storing the product
• Humidity
— 5% to 85% non-condensing for normal operation
— 5% to 90% non-condensing (but not to exceed 0.024 kilograms of water per
kilogram of dry air) for no more than 96 hours in duration and at
elevations less than 1800 meters
Tekelec products are tested to operate at an elevations within the following range:
• Minimum: 60 meters below sea level at ambient temperature of 30° C (86° F)
• Maximum: 4000 meters above sea level at ambient temperature of 40° C
(104° F)
HVAC Requirements
Tekelec products are designed to bring cool air in from the bottom front and exit
heated air out the top rear of the installed equipment.
The required HVAC (Heating, Ventilation, and Air Conditioning) capacity
depends on the installed equipment. To calculate needed HVAC capacity,
determine the total wattage of the installed equipment and use the following
formula:
BTUs/hr. =

Lighting
Adequate lighting should be provided in the room where the equipment is to be
located. Lighting fixtures must be far enough from the equipment and cables to
prevent heat damage and to allow safe access to equipment and cables.
