Step 1: Mount the MDU
CAUTION
!
The MDU should only be installed by qualified service personnel.
Consideration should be given to proper clearances for opening the MDU
door. Ensure that the door can be opened completely.
To mount the MDU, complete the following steps:
1. For outdoor installation, choose a vertical surface near an approved
ground, but away from down spouts, permanent water sprinklers, or
other water sources.
2. Use the top and bottom external mounting holes as a template to mark
fastener locations. Use a level to ensure the unit is level and the door will
open and close properly.
3. Pre-drill the marked locations and install two, 5/16 or 3/8-inch diameter
lag bolts that are appropriate to secure the MDU to the mounting
surface. The MDU housing with four ONTs, and associated cabling will
weigh approximately 25 pounds.
4. Mount the MDU.
Step 2: Ground the MDU
WARNING
!
Use extreme care when attaching the ground connectors to the utility (earth)
ground rod. If the ground is interrupted or disturbed in any way, an unsafe
condition will exist. Refer to the National Electrical Code (NEC) and state and
local codes for details on grounding requirements.
Refer to Figure 1 to ground the MDU.
1. Strip 5/8 of an inch of insulation from a 6 AWG ground wire and crimp
the grounding lug (P/N 3198001PN21-E) to the wire using the appropri-
ate crimping tool (i. e., Burndy Type Y35).
2. Attach the Ground Lug at the right-rear of the MDU housing with 2
Lock Washers (P/N 3284018-E) and 2 Screws (P/N 327611028-E).
a. Apply antioxidant to all grounding surfaces.
b. Attach ground lug with two #10 lock washers and two,
10-32 x 3/8-inch machine screws.
c. Torque the screws to 24 inch/pounds.
3. Apply the appropriate anti-oxidant and connect the opposite end of the
ground wire to a reliable earth ground.
Step 3: Connect Power to MDU
CAUTION
!
Do not turn the power source on until the MDU installation is complete.
To connect power to the MDU, refer the Power Distribution Block (P1) in
Figure 1, the Wire Chart and PCB (P1) portion of Figure 2 and complete the
following steps:

the MDU Housing, and remove the Support Bracket from the MDU
Housing.
3. Refer to Figure 6 and align the Standoff Nut/Screw with the Rear of the
“Teleco Access Only” Connector and the Support Bracket.
4. Attach the Support Bracket to the ONT by inserting a #10-16 Plastite
Screw (P/N 327600205-E) through the upper-left side and lower-right
side of the Support Bracket and into the ONT and tighten. Ensure the
