Remember that the temperature within a protective enclosure is
generally higher than the external temperature. Thus, if the PA
PowerStation is operating inside an enclosure at temperature levels
above its rated ambient temperature, you must cool the enclosure.The
PowerStation conforms to the environmental specifications listed in
Environmental Specifications Chart.
Electrical
Specifications
The PA PowerStation’s power supply automatically detects the input
voltage level and adjusts accordingly. However, always use reliable
sources of power, and isolate all communication cables from AC
power lines to enhance noise immunity.
If possible, locate the PA PowerStation away from machinery that
produces intense electrical noise (arc welders, etc.). Otherwise, isolate
the input power to the PowerStation from the equipment generating
electrical noise.
