ACU-5000 Operations Manual
2-2 Interoperability Now
2.2 Installation Considerations
The ACU-5000 must be installed in a location that provides both protection from the weather
and assurance of ambient temperatures between 0 and +40 degrees C. The unit is neither splash
proof nor corrosion resistant and must be protected from exposure to salt spray. When the unit
is mounted in a cabinet with other heat-generating equipment, the use of a rack blower is
suggested to keep the cabinet interior temperature rise to a minimum.
Care should be taken to allow free airflow and not obstruct the intake to the cooling fans and the
unit’s air exhaust holes.
Note: When the ACU-5000 is installed in a high RF environment such as
repeater site, it is recommended that cable assemblies to each channel
be individually shielded.
Interface cables purchased from JPS are shielded.
2.3 Power Source
The unit is powered by an external supply similar to those typically used to power a standard
laptop computer. The power supply included with the unit operates from input voltages and
frequencies of 100 to 240 VAC, 50 - 60 Hz. Other standard “laptop-type” supplies can be
substituted, but must provide a nominal +12 VDC, and be capable of at least 40 watt output.
2.4 Mechanical Package
The tabletop version of the unit is housed in a small portable package, rectangular in shape, 13”
wide, 9.25” deep, and 1.8” high.
The rack mount version of the unit is housed in a black aluminum 1U high enclosure, 19” wide,
9.7” deep, and 1.75” high.
