AM-6060 Computer Owner's Manual, Rev. 00
A point to remember is that the closer you get to either end of the AC voltage power range, the less
efficient the computer will be.
If you use an Uninterruptible Power Supply (UPS) with your AM-6060, we recommend at least a
1kVA unit which provides a minimum of 20 minutes of run time on battery power.
To avoid electrical interference, sources of electrical noise such as air conditioners, copiers, electric
typewriters, or cleaning equipment should not be connected to the same power circuit as the computer.
All outlets providing power to the computer should have a common grounding point restricted to only
those connections coming from the computer installation.
Be sure to follow all Ethernet network configuration and cabling specifications. With almost all
users connected via the network, reliable network performance is critical to the AM-6060. While
non-conforming configurations sometime work adequately in small tests, they almost always
degrade performance or fail completely during actual use.
Data cables should not be located near high voltage power lines, power transformers, telephone cables,
or in elevator shafts. They should not cross walkways. If you must cross walkways, cover the cables with
a cable bridge.
You must also take cable lengths into consideration. Single-ended circuits are susceptible to all forms of
electromagnetic interference. As line length increases beyond fifty feet, the reliability of the RS-232C
cable connected to a terminal or printer decreases rapidly. If local terminals are to be located further than
fifty feet from the computer, we recommend you use low capacitance twisted-paired overall shielded
cables. If this cable does not solve your problem, then signal conditioning equipment (such as a
Speedway Repeater) will be needed to improve the signal.
Verifying Voltage Compatibility
Different parts of the world use different standards for electricity. For example, most areas of the United
States use 115 Volt electricity. Many other areas of the world use 220—240 Volt electricity.
The AM-6060 can work with either voltage if its input voltage switch is set correctly. The switch is on
the power supply near the top of your computer’s back panel. Verify the input voltage setting before
plugging in your computer.
If your computer is not set to the voltage you require,
do not
change the switch setting without
checking with your VAR first. Your VAR will insure that you have the proper input voltage
switch setting and power cord for your installation.
The power supply has one standard AC power receptacle. One standard AC power cord is packaged with
your computer.
