System Location and Environment
The VS-KSU Control Module and the internally mounted VS-PWSU power supply are UL and CSA
listed, fulfilling the safety requirements mandated by the governments of the United States and
Canada. However, environmental and structural considerations, AC power and grounding
requirements and trunks characteristics must be met to ensure proper system operation. As with all
processor controlled voice and data equipment, the proper operating environment is necessary for
reliable operation and long-term system performance. These conditions are explained below.
Environmental and Structural Conditions
It is important to satisfy with careful consideration the environmental conditions specified for system
installation. The environment in which the ADIX-VS and key telephones are located must be free of
moisture, fumes, dust and vibrations. Any deviation from the recommended environment may affect
the proper operation of the ADIX-VS System. If you expect to operate the system in an extreme
environment, you should be aware of these limits:
Operating Temperature 0 to 40 degrees Centigrade ( 32 to 104 degrees Fahrenheit)
Storage Temperature -10 to 50 degrees Centigrade (14 to 122 degrees Fahrenheit)
Relative Humidity (non condensing) 10 to 90% at 24 degrees Centigrade ( 75 degrees Fahrenheit)
Static Discharge 10 KV or less
Electromagnetic Interference 0.3 V/ft. or less
Ventilation At least three inches above and to the sides of the IX-CML/IX-EXPML and power supply
Floor Strength 200 lbs. per sq. ft.
VS-KSU Control Module Location
The VS-KSU Control Module is designed to be either mounted on a wall. When selecting the
location for the units, be sure that all conditions for AC power and grounding are satisfied. These
requirements are specified starting on page 18. It is recommended that you:
■
Mount the VS-KSU Control Module within five feet of a dedicated three-wire grounded
AC outlet.
■
Install the VS-KSU Control Module within twenty-five feet of the network interface
provided by the local telephone company or the cross connect serving the area of the
building where the VS-KSU Control Module is installed.
■
Allow enough space for air circulation and the installation of additional equipment (e.g.,
MDF blocks, PC equipment).
■
For floor mounting, allow enough space from the floor to prevent flood damage to the
ADIX-VS System.
