OPERATING INSTRUCTIONS
Hook-up
1. Disengage the INDEP/TRACK mode switch so that the
power supply is in the INDEPendent operating mode.
2. Turn off the power supply and the equipment to be powered
during hook-up.
3. Connect the positive polarity of the device being powered to
the red (+) terminal of the power supply.
4. Connect the negative polarity of the device being powered to
the black (-) terminal of the power supply.
5. Fig. 3 illustrates the grounding possibilities when used in the
INDEPendent mode.
a. If the negative polarity of the equipment or circuit being
powered is also the chassis or common, it may be
grounded to earth by strapping the black (-) terminal to
the green (
) terminal as shown in Fig. 3A.
b. Similarly, the positive polarity can be grounded by
strapping the red (+) terminal to the green ( )
terminal as shown in Fig. 3B.
c. If an earth ground reference is not required, the
configuration of Fig. 3C may be used. The scheme
in Fig. 3C should also be used where it is not
known whether the chassis is common with either
the positive or negative polarity.
d. If the chassis or common of the equipment being
powered is separate from both the positive and
negative polarity power inputs, use the connection
shown in Fig. 3D.
6. Observe proper polarity. If the circuit being powered
is not equipped with reverse polarity protection,
damage to the circuit can result from reverse polarity.
Use color coded hook-up leads, for convenience in
identifying polarity, red for (+) and black for (-).
7. Make sure that the hook-up leads offer sufficient
current capability and low resistance between the
power supply and the circuits being powered.
