MODELS 5843HRT, 5843SHRT, 5844HRT & 5844SHRT
INSTALLATION PROCEDURE
FOLLOW THESE STEPS TO INSTALL A LINK/REPEATER.
1. Set the DTE/DCE Switch and the Repeater Mode Switch to the appropriate position.
2. Connect an earth ground wire to the ground lug on the face of the unit. The ground stud has three nuts
attached.
NEVER LOOSEN OR REMOVE THE BOTTOM NUT CLOSEST TO THE UNIT.
The two other
nuts are used for attaching the ground wire. Place the ground wire between these two nuts and securely
tighten the nuts together.
WARNING
WHEN INSTALLING A MODEL 5843 or 5844 LINK/REPEATER, AN EARTH GROUND MUST BE
ATTACHED TO THE GROUND STUD ON THE FACE OF THE CASE BEFORE CONNECTING POWER.
FAILURE TO FOLLOW THIS PROCEDURE MAY RESULT IN ELECTRICAL SHOCK TO PERSONNEL.
3. Connect the Link/Repeater's 9 pin connector to the appropriate communication port on the IED. This
connection may be made by either directly plugging the Link/Repeater into a standard RS232 9 pin D
Connector on the IED (make sure not to over tighten the D Connector screws) or by means of an adapter or
extension cable (make sure that the pin assignments are correctly matched).
4. Connect the Fiber Optic Cable (FOC).

Note:
The FOC must connect a "T" optical port of one Link/Repeater to the "R" optical port of another
Link/Repeater.
5. Connect the power source to the Link/Repeater.
Î
Note: The LEDs do not illuminate when power is applied. They illuminate only when data signal traffic
occurs
.
If powering through the power connector on the side of the unit:
•
Check the Link/Repeater's voltage rating, stamped next to the power connector and verify it matches
the power source.
•
Remove the plug portion of the power connector by loosening the two captive mounting screws.
•
Strip back 1/4" off the insulation of the wires that will connect the unit to the power source.
•
Insert each conductor firmly into a terminal hole of the plug (note: this connection is not polarity
sensitive).
•
Visually inspect that no strands of wire are straying out of the hole, potentially shorting to ground or
the other conductor. Tighten the saddle screws until secure. Re-insert the plug into the power
connector and secure the two captive mounting screws.
•
Connect the power leads to the power source. (The input is non-polarized.) The unit is now powered.
6. Verify operation. When powered and transmitting, LEDs TE & TO illuminate. When receiving, RO and RE
LEDs illuminate. When in repeat mode and receiving, both RO and RE LEDs as well as the optical TO LED
illuminate.

Note:
The LEDs "flicker" as data passes through the Link/Repeater. This is normal operation.
