ONT180C Installation and Turnup Guide
Page 28 of 38
Have a (locally sourced) Phoenix-type pluggable terminal connector (5.08 mm pitch 2P)
available. This procedure is for a connector with screws.
Do not plug the connector block into the ONT yet.
1. At the bulk DC power supply turn off or disconnect the DC power for the cable
connecting to the location where the ONT is being installed. Note which wire
(color/stripe/etc.) is positive.
2. Return to the ONT installation location and use a DMM to make sure that there is
no voltage on the wires of the remote bulk DC cable before proceeding further.
3. Strip about 3/16 inch of insulation from the ends of the DC wires and twist the
strands of each wire tightly.
4. Install the Phoenix-type pluggable terminal connector on the end of the remote
bulk DC cable taking care to ensure the screws are tightened properly. The
polarity marked on the ONT rear panel above the DC 54V power connector must
be observed. Note that if the connector has reversed polarity, the ONT will not
be damaged when powered up. It just will not operate.
5. Go to where the bulk DC power supply is located and restore power to the DC
cable.
6. Return to the ONT installation location and use a DMM to make sure that DC
power (~ 54 VDC) is available at the Phoenix power connector and the polarity is
correct. If polarity is reversed, shut off power to the DC cable, reverse the cable
connections at the connector, and restore power.
7. Plug the Phoenix DC power connector into the ONT DC 54V connector.
If the remote DC bulk power supply is on, the ONT Power LED Indicator will come on in
about five seconds and be steady green. (See the ONT180C LED Indicator Quick
Reference Table in the Operation chapter.)
