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.

Back of Electronics Module

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.
