the 48 VDC power supply.
2. Mount the Network Station Power Supply (P-NSPS-D) and the 48 VDC
Power Supply.

3. Connect LinkConnect station wires to the eight-position removable
pluggable connector on the bottom of the P-NSPS-D.
a. Run up to four LinkConnect data runs (Belden 8471 or equivalent) to
the P-NSPS-D. Strip 7 mm (1/4 in) from the ends of each.
b. Terminate the data + wire (typically white) from one wire pair to
terminal A and the data - (typically black) from the same wire pair to
terminal B. Secure each wire in place using a 3 mm slotted screwdriver.

c. Repeat for each wire pair to a new set of A and B terminals on the
eight-position connector.
d. Reinstall the eight-position connector.
4. Connect the 48 VDC power pigtail (provided) between the 48 VDC Power
Supply and the Network Station Power Supply.
a. Install the three-position pluggable connector from the pigtail to the
48 VDC input receptacle on the P-NSPS-D.
