Installation, Wiring, and Specifications

Power Wiring

The power wiring is attached to the terminals on the right side of the D4–470. Follow the legend on the upper right corner of the hinged lid as shown in the diagram below.

WARNING: Do not strip wire insulation more than 8–10mm, or approximately 0.3875 inches. Use spade or ring lugs if possible. Exposed conductors longer than this length could make contact with the metal case of the D4–470. Contact between the conductors and the case could be hazardous.

100-120/200-240VAC~ 50/60Hz

Logic Ground

Chassis Ground

 

 

 

NOTE: We recommend including an on–off switch in the power circuit of the

 

 

 

D4–470. This will make it easier to cycle power to the unit when necessary.

 

 

 

 

Internal Power

 

The D4–470’s internal power supply distributes power to the CPU–board, the CPU

Supply

fan, the hard disk drive, and the floppy disk drive. Additional power is also available

 

 

 

to power the expansion slots. Three voltages are provided to power internal devices:

 

 

 

+5, +12, and –12 VDC. You will find the current limits for each voltage in the

 

 

 

specifications on page 2–7. Be sure the total power consumption does not exceed

 

 

 

the available power limits.

Power Supply

Many peripheral devices consume more power than the D4–470 can furnish. We

Limitations

recommend that you do not attempt to power external devices using the internal

 

 

 

power supply. Do not attempt to power a CD–ROM drive using the D4–470’s

 

 

 

internal power supply. Use an external power source.
