Ground Connection
Refer to the illustration below and in the opposite column to install the
ground connection:
1. Remove the rubber grommet from the housing and insert a #6 solid
copper ground wire through the rubber grommet.
2. Replace the rubber grommet in the housing.
3. Route the ground wire 12 inches below finished grade by the
shortest and most direct route to the AC power ground system
Multi Grounded Neutral (MGN) of the customer premises. Ensure
the wire is free of any sharp bends.
4. Attach the ground wire to the side of the subscriber's premises with
stainless steel half moon clamps or tie‐wrap the ground wire to the
riser conduit of the Buried Fiber Drop.
5. Clean the MGN connector with emery cloth to insure a stable
connection.
6. Attach the ground wire from the SFU ONT to the MGN connector
with the appropriate UL approved ground clamp/fitting.
7. Coat the connection with a metal corrosion preventative.
8. Attach a Warning Ground Tag to this grounding connection.

Power/Alarm Connections
NOTE
Wiring the Power/Alarm connector improperly could damage the SFU.
The SFU ONT is supplied with a 7‐conductor Euro‐Type Power/Alarm
Connector. To make connections from the UPS to the power connector
complete the following steps:
1. Remove the Power/Alarm Connector by pulling it out of the elec‐
tronics module.

2. Refer to the illustration on the opposite 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 UPS
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. 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. Reinstall the Power/Alarm Connector.
6. Tie Wrap the wires as appropriate.

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 below for fiber installations:
1. Place the OptiTap fiber drop in the same rubber grommet channel
as the ground cable. The ground cable should be "behind" the Opti‐
Tap 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 power wires
so that they are not pinched when the Electronics Module is closed.
Install SC/APC Optical Connection
NOTE
Refer to the Total Access 300 Series GigE SFU ONT with RF Overlay and
SWRD Powering Installation and Maintenance Guide (P/N 64187712G2‐5) 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
The SFU ONT needs to be powered by a UL Listed Power Supply suitable
for the application with Output at LPS Levels.
This SFU ONT should only be operated from the type of certified/listed
power supply recommended by the power supply manufacturer.
