•
Individual fibers identified as Transmit and
Receive.
•
A report from the fiber installer showing the
loss of optic power per section of fiber cable,
including all connectors. The loss must be
less than the required link budget.
•
Source of transient protected for 115 Vac or
230 Vac. All field panel outlets are protected
or an MOV protected 120 Vac duplex outlet
(P/N 529-804), or three 250 V operation
(refer to Figure 7) can be ordered.
•
The BLN or FLN trunk has been checked for
opens, shorts, and proper shielding.
•
The mounting bracket (if used), or other
locally fabricated bracket, is available.
Instructions
1.
If wall or rack mounting brackets are being
used, refer to the installation instructions for the
brackets (P/N 538-718).
2.
Remove the protective cap from the transmit
port and transmit fiber, and connect the fiber to
the port labeled “TX” (refer to Figure 2). Do not
use any tools to tighten the connectors.
3.
Remove the protective cap from the receive
port and receive fiber, and connect the fiber to
the port labeled “RX” (refer to Figure 2). Do not
use any tools to tighten the connectors.
4.
Connect the BLN or FLN trunk to the trunk
connector. Then plug the connector into the
port labeled “Trunk” on the interface.
5.
Connect the earth ground wire (2’ green wire,
included) from the trunk shield connection to
earth ground. The ground can be either the field
panel chassis using the nutdriver to put the
ground terminal under the chassis mounting nut
or the electrical box which powers the interface.
6.
Connect the power connector into the interface
and plug the power pack into a transient
protected source.
The installation is now complete.
