Preparing the 5071A For External-DC Operation
Use the dc-power connector (supplied) that mates with the Ext DC
Input connector on the rear panel, to connect dc power to the 5071A.
Follow the procedure below to set up and verify operation from
auxiliary dc power:
1
Connect the positive (+) terminal of the 22 to 42 VDC power to pin A of the 5-
pin Series ME, Cannon connector.
2
Connect the negative terminal of the external dc power to pin C. (Either line of
the external-dc source may be grounded.)
3
Connect the chassis ground to pin E. (The two remaining pins are not used.)
4
Check the connections for correct polarity and voltage range.
5
Connect external-dc power to the rear-panel Ext DC Input connector.
6
Remove ac power from the rear-panel ac-power input connector. Observe the
front panel, the ATTENTION light remains extinguished and the front-panel
status message will read: ―Source: DC‖. Refer to Table 2-2 for more status
details.
7
Re-apply ac power, the front-panel status message reads: ―Source: AC‖.
Follow the procedure below to set up and verify operation from
auxiliary dc power:
1
Connect the positive (+) terminal of the 40 to 58 VDC power to the + screw
terminal of
INPUT 1
on the rear-panel 5-terminal barrier strip.
2
Connect the negative (-) terminal of the 40 to 58 VDC power to the - screw
terminal of
INPUT 1
on the rear-panel 5-terminal barrier strip.
3
Connect the system or power source ground to the 3
rd
(center) screw terminal of
the rear-panel barrier strip labeled chassis
GND
.
4
Check the connections for correct polarity and voltage range, and tightness
before you turn the dc power on.
5
If a second 48 Vdc power source will be used, repeat steps 1 through 4 with
INPUT 2 of the rear-panel barrier strip. (
INPUT 2
will be an alternate power
source if
INPUT 1
should fail, be disconnected, or sag below the voltage of
INPUT 2
).
6
Connect external ac power to the rear-panel ac input connector.
7
Remove dc power from
INPUT 1
(and
INPUT 2
if connected) on the rear-panel
barrier strip. Observe the front panel, the status message should read: ―Source:
AC‖.
8
Re-apply dc power, the front-panel status message reads: ―Source: DC‖.
