Several anti-static sprays on the market can be of considerable help during days when
static electricity is a problem. Also, using an air conditioner that controls humidity can
greatly reduce a static electricity problem.
Power and Cable Connections
Before selecting a site for your computer, you should determine if the area where you
want to place the computer has adequately regulated AC power. If you request it, many
power companies will install test equipment to determine if there is a need for additional
line regulation. Testing line voltages may also be done through the use of a high speed
line transient recorder. If, over a period of several days of testing, the line voltage varies
more than 10 percent from the rated line voltage, you may need to install a power
conditioner and a new dedicated ac power circuit. AM computers require a properly
grounded power outlet for the system to run correctly.
A "transient free," or smooth and consistent, power source and a properly installed earth
ground can significantly improve the reliability of your computer. While the computer is
in use, it is important to maintain a constant line voltage free of power surges,
fluctuations and impulses. Ideally, a separate power source should be available for use
only by the computer. However, if this is not possible, you may need a line conditioner
capable of suppressing transients or spikes to eliminate power surges and noise.
Be sure the power rating for the power lines the computer will be connected to is
adequate for your computer or any future systems you may be planning to install. In
North America, a standard 15 amp 115 volt grounded connector-type outlet is required
for the CPU chassis. In some other countries, the requirement is a 230 volt AC power
source.
The maximum power requirements for the computer are:
115 Volt AC at 5 amps, or
230 Volt AC at 3 amps
Additional outlets are required for each I/O chassis and/or peripheral connected to the
computer. Alpha Micro computers come with a standard six-foot power cord. If this is
not long enough, be sure any extension cords used are rated for the full 15
amps—otherwise, the full voltage will not reach your computer. This can affect the
efficient operation of your computer.
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.
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.
