Figure 3-3 Terminal Block on Rear Panel
3. Connect the -48 VDC wire to the - terminal (on the rear panelÕs
terminal block, Figure 3-3) using a small ßat screw driver to fasten
the wire.
4. Connect the ground (+) wire to the + terminal in the same way.
5. To minimize disturbance to the wires through casual contact,
secure a tray cable near the rack frame using multiple cable ties.
Use at least four cable ties, a minimum of four inches apart. The
Þrst tie should be within six inches of the terminal block.
6. Connect the DL3100 to a DC power source.
The DL3100 automatically runs a self-test at power up, during which the
front panel displays a self-test message. Payload service resumes upon
completion of the self-test and the front panel displays the following
default message:
EFS 00.0 PERCENT.
NOTE: The unit is designed to operate with negative voltage;
therefore, you must connect the positive terminal to ground.
WARNING: Damage to the DL3100 may result if power is connected
improperly.
Do not operate the DL3100 without an earth ground connection to the
ground stud or FGND terminal!
