OPERATING INSTRUCTIONS
Fig. 8. Series Tracking Operation Grounding Possibilities
a. Similarly, the positive polarity can be grounded by
strapping the red (+) terminal of the “A” supply to the
green terminal of the “A” supply as shown in Fig. 8B.
b. If “split supply” operation is desired, a positive and
negative voltage with a center ground can be achieved
by strapping the black (-) terminal of the “A” supply
to the green (
) of the “A” supply as shown in Fig.
8C. See the APPLICATIONS section of this manual
for more information on “split supply” operation.
NOTE
If one of the supplied ground straps is to be used,
only use it in one of these three ways. Connecting
two ground straps could ground both the positive
and negative terminals and load down the power
supply, causing improper operation.
c. If an earth ground reference is not required, the
configuration of Fig. 8D may be used. The scheme in
Fig. 8D 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. 8E.
