2. Refer to the illustration at the top of the next column and
“Local Power Source Wiring” section to assist in completing
the next steps.
3. Remove the rubber grommet from the housing and insert
the power and ground cable through the grommet.
4. To terminate the two UPS power leads (Pins 6 and 7) and, if
needed, the five alarm status leads in the power connector,
cut all wires and strip back the insulation. Use a flat head
screwdriver (or similar device) and loosen all the screws on
the Power Alarm Connector. Insert one wire at a time and
tighten the screws to make an electrical contact.
5. Reconnect the Power/Alarm Connector to the bottom of the
Electronics Module.
6. Tie Wrap the wires through the holes just below the Power/
Alarm connector.
7. Replace the rubber grommet while closing the Electronics
Module. This places less stress on the wiring and allows the
Electronics Module to close without pinching any wiring.
Route OptiTap Fiber Drop Cable
Refer to the illustration on the following page for fiber installa-
tions:
1. Place the OptiTap fiber drop in the same rubber grommet
channel as the ground cable. The ground cable should be
“behind” the OptiTap fiber.
2. Connect the OptiTap fiber.
3. Place the OptiTap connector in the cut-out in the housing.
4. Connect the fiber cable to the connector on the bottom of the
Electronics Module.
5. Route the cable so that when the Electronics Module is
closed, the fiber is not pinched.

NOTE
There are wire routing clips on the lower right of the Electronics
Module housing. It is recommended that these not be used. Route
the fiber optics cable so that they are not pinched when the
Electronics Module is closed.
Install Optical Connection
NOTE
Refer to the
Total Access 351 2 POTS/1 Ethernet SFU ONT
Installation and Maintenance Guide
(P/N 61287701G1-5) for
information on installing the SC/APC optical connection.
To install the optical connector, complete the following:
1. With the electronics module swung open, route the fiber
through the most direct grommet entrance and connect it to
the appropriate SC/APC optical connection.
2. Check that there are no bends in the fiber less than 30 mm
(1.2 inches) radius or 60 mm (approximately 2.5 inches) in
diameter. When the maintenance door is closed, it should
not come in contact with the fiber.
Local Power Source Wiring
Installation of the Local Power Source (LPS) will be dictated by
on-site conditions and local telephone company practices. Refer
to the
Total Access 351 2 POTS/1 Ethernet SFU ONT Installation and
Maintenance Guide
(P/N 61287701G1-5) for complete information
on connecting to the LPS.
WARNING
!
•
Before making any power connections to this equipment, verify
the power is off (fuse removed/breaker tripped).
•
The SFU ONT needs to be powered by a UL Listed Power
Supply suitable for the application with Output at LPS Levels.
CAUTION
!
To reduce the risk of fire, use minimum no. 26 AWG
telecommunications line cord.
