Connecting IFSF Wiring to TLS-IB
1. With AC power switched Off, connect the IFSF network wires to J8 in the TLS-IB as shown in Figure 26 below:
Figure 26. Connecting IFSF Network wiring to TLS-IB
2. The LON cable termination jumper (JP3 in Figure 26) is shown in the single position (SGL). The single position is
used when the TLS-IB is a Free Topology Segment in the LON network and only one termination is required. The
double position (DGL) is used when the TLS-IB is a Doubly Terminated Bus Topology Segment in the LON network
and two terminations are required. To set the jumper in the DGL position, move it to the right (jumper over the
middle and right pins).
WARNING
The TLS-IB’s circuit boards have lethal voltages present.
Care must be taken when installing, servicing or replacing parts in the system
or serious injury or death shock may occur.
For this system:
1. Comply with the latest National Electric Code, federal, state, and local
codes, and any other applicable safety codes. In addition, take necessary
precautions during installation, service, and repair to prevent personal
injury, property loss and equipment damage.
2. Refer servicing to trained and qualified personnel only.
3. Substitution of components may impair intrinsic safety.
4. Be sure AC power is “Off” before opening the TLS-IB cover and
connecting wiring.
