Direct Current (DC) Power Supply - Continued
c.
Power Supply Setup (fig. 8-17). The proper procedure for setting up and connecting a power supply to a
circuit is as follows:
(1)
Be sure the ON-OFF switch (8) is in the OFF position.
(2)
Connect power supply cord to a power source of proper voltage and frequency.
(3)
Turn the VOLTAGE adjust knob (6) fully counterclockwise.
CAUTION
Always check for the proper polarity of voltage necessary to operate the equipment or chassis.
Failure to observe voltage polarity could result in damage to equipment or chassis.
(4)
Connect one end of a lead to the - output terminal (4). Connect the other end of the lead to the
appropriate terminal of the equipment or chassis.
(5)
Connect one end of a lead to the + output terminal (5). Connect the other end of the lead to the
appropriate terminal of the equipment or chassis.
(6)
Connect one end of a lead to the GND terminal (3) and connect the other end to the equipment ground.
(7)
Turn ON-OFF switch (8) to the ON position. Power ON lamp (7) will light.
NOTE
To verify that the DC VOLTS meter is indicating properly, use a Multimeter across the + and -
output terminals to read the dc voltage while adjusting the output.
(8)
Turn the VOLTAGE adjust knob (6) slowly clockwise until the DC VOLTS meter (1) indicates the desired
voltage.
(9)
When finished with the power supply, turn the VOLTAGE adjust knob (6) fully counterclockwise.
(10) Turn ON-OFF switch (8) to the OFF position.
(11) Disconnect leads from the equipment and the power supply.
