6. The power supply board is not fastened to the main isolation card prior to
shipment and, therefore, requires installation first. Unfasten the cover of the
unit and proceed as follows:
?
Remove the screws from the tops of the spacers mounted on the Station side
circuit board.
?
Position the power supply board onto the spacers and align the board holes
with the spacers.
?
Secure using the four screws with the nylon screw going on the spacer in
the isolation gap.
7. Fasten the 1” thick plywood backboard to the wall.
?
Mount the enclosure onto it using the four screws supplied.
Note
The Station (subscriber) side of the enclosure may be identified by two
access holes, one for the telephone cable and the other for the power cable.
The CO (remote) side has only one hole for the telephone cable entry. The
orientation of the unit does not matter.
8. Plug the power supply’s output connector into receptacle J4 of the main
isolation card.
To locate J4 and the output of the power supply, refer to Figure 2.
9. The strain reliefs supplied each have a cable entry diameter appropriate to
one of the three cables employed in this installation. The CO cable strain
relief is the largest, accommodating a cable diameter from 0.375” to 0.570”.
The power cable strain relief accommodates a cable diameter from 0.250”
to 0.570”, and the station cable strain relief accepts a cable diameter from
0.125” to 0.275”. All measurements are the outside cable diameters.
?
Slide the strain reliefs supplied onto the CO, station, and power cables and
affix them to the unit.
?
Route the power cable and the two telephone cables, allowing a length of
five inches per cable for the internal connections to the terminal blocks. Cut
the excess wire once the exact internal length is established, and tighten the
strain reliefs.
