Table 2-2: Maximum DC Power Requirements
The power requirements noted above are as observed during testing. Power requirements may
vary depending on DRAM manufacturer.
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.
Data cables should not be located near high voltage power lines, power transformer 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 the terminal and 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.
Power Supply AC Voltage and Receptacle
The voltage select switch in the rear panel is factory set to 115 Volts. By simply sliding the switch to the
opposite position, you can convert the power supply for 230 Volt operation.
The power supply has one standard AC power receptacle. One standard AC power cord is packaged
with your computer.
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.
Verify the input voltage before plugging in your computer. The illustration of the back panel earlier in
this chapter shows the location of the input voltage switch.
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.
