MODELS 5941D1, 5941SD1, 5942D1, & 5942SD1

1. Model 5942 and Model 5942S ONLY - Before connecting power, secure an earth ground wire to the ground stud

on the side of the unit. The ground stud has two nuts attached. The two nuts are used for attaching the ground wire.

Place the ground wire between these two nuts and securely tighten the nuts together.

WHEN INSTALLING A MODEL 5942 OR 5942S LINK, AN EARTH GROUND (MINIMUM 14 GAUGE WIRE,

UPTO 5 FOOT LONG) MUST BE ATTACHED TO THE GROUND STUD ON THE SIDE OF THE CASE BEFORE

CONNECTING POWER. FAILURE TO FOLLOW THIS PROCEDURE MAY RESULT IN ELECTRICAL SHOCK

TO PERSONNEL.

2. Connect the Link to the communication port of the IED. Check the IED configuration to be sure of the correct

function and direction (signal flow) of each circuit. Typical connections are shown in the following table.

Note: The Link does not use nor require the connection of these functions for its own operation.

Note: The Signal Common pin (pin 5) of the Link is shared among all the channels.

3. Connect the Fiber Optic Cable (FOC).

Note: The FOC must connect a "T" optical port of one Link to the "R" optical port of the other Link. Both fibers must be

the same length. The use of duplex fiber is recommended.

4. Connect the power source to the Link.

•

Check the voltage rating next to the power connector - verify that 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 to the other

conductor. Tighten the saddle screws until secure

•

Re-insert the plug into the power connector and secure the two captive mounting screws

5. Connect the power leads to the source. (The input is non-polarized). The unit is now powered.

6. Immediately upon both links being energized, the "POWER ON" and the "SYNC" LEDs will illuminate "steady".

7. The Links and the optical circuit are now fully operational. The "CH.1 T", "CH.2 T", "CH 3 T" and the "CH.4 T" LEDs

will illuminate when the Link is transmitting optical signals. The "CH.1 R", "CH.2 R", "CH 3 R" and "CH. 4 R" LEDs

will illuminate when the Link is receiving optical signals.
