- Securely attach the Fieldbus Segment Protector at the desired location. Choose a location that minimizes the length of the spur cables.
- For the trunk segment connection: connect the positive (+) segment wire to the positive; connect the negative (-) segment wire to the negative; and connect the segment shield (S) to the S.
- For each device connection: connect the positive (+) spur wire to the positive, connect the negative (-) spur wire to the negative, and connect the shield wire (S) to the S.
- The two shorting jumpers must be repositioned so that the trunk (T) and spur (S) shields are connected together and not connected to case. Jumper T to S and Gnd to Gnd.
- If this Segment Protector is at the end of the segment, the terminator switch S1 should be in the On position. If it is not at the end of the segment, ensure that terminator switch S1 is in the Off position.
- If the segment continues and connects to another Segment Protector, continue the Trunk segment by connecting the Trunk Out connections to the next Segment Protector and proceed with the connections described in steps 2, 3, and 4.
- For all Segment Protectors, ensure that the two shorting jumpers are repositioned so that the trunk (T) and spur (S) shields are connected together and not connected to case. Jumper T to S and Gnd to Gnd.
- At each device ensure that the shield is isolated and not connected to the device.
- If this Segment Protector is at the end of the segment, ensure that the terminator switch S1 is in the On position.
- Verify the installation.
