TECHNICAL INFORMATION
SECTION 1 - PREPARATION AND SET-UP
Summary: By following the instructions and information presented
here, the technician can be assuread that all outside vairables -
power sources, tools, and test programs - are in the optimum
conditions for troubleshooting the Vector 4 SBC. Since the

12 Yector 4 SBC Power Requirements
The Vector 4 uses a Switehing Power Supply which provides regulated, DC
voltage to the Monitor (+12 V), main PCB (+5 V, =12 V, +12 V) and drives (+5
V, +12 V). For accurate troubleshooting, make sure that the Vector 4 is
supplied with current which meets the following specifications:
Voltage Options
115 AC +/- 15% 230 AC +/- 15%
Frequency 47 Hz to 63 Hz 47 Hz to 63 Hz
Current, Operating (1) 2 A 1 A
Current, Surge (1) 2 A 1 A
Power Dissipation (1) 190 W 190 W
Heat Generation (1) 60 BTUs 60 BTUs
(1) Maximum values.
Before beginning to troubleshoot the Vector 4, make sure that a dedicated
power line or power line conditioner, supplying the specified current, is
available. Make sure that no machinery or equipment drawing large amounts
