!
below.
The equipment should not be exposed to direct sunlight, corrosive fumes, dust,
!
constant vibration or strong magnetic fields such as those generated by motors and
copy machines.
A direct commercial AC power outlet is required. Do not use extension cords.
!
Preferably, a dedicated circuit should be used to minimize the risk of other electrical
equipment being connected that could adversely affect system operation.
Ensure that all wires and cables going to and coming from the KSU are properly
!
routed. Do not cross fluorescent lights or run parallel with AC wires.
The equipment must be located in an environment that will maintain a temperature
!
range of 32°–104°F (0°–40°C) and a humidity range of 10%–90% non-condensing.
Allow at least 6" clearance on both sides and 6" clearance on top of the KSU to
!
ensure proper ventilation.
Do not install in close proximity to a fire sprinkler head or other sources of water.
!
Meeting these requirements will help to ensure proper performance and greater life
expectancy of the system.
