1、®U.S. Registered TrademarkCopyright © 1997 Honeywell Inc. All Rights Reserved BEFORE INSTALLATIONE-Bus Free Topology Transceiver (FTT/Linked PowerTransceiver (LPT networks require termination. Dependingon the network topology, one or more FTT/LPT TerminationModules may be required, see Fig

2、. 1. If an FTT Repeateror a LPT device is required in the network, their on-boardterminators can be used in place of the 209541BTermination Module. Refer to the E-Bus Wiring Guidelines, form 74-2865, for complete rules on network topology andtermination module locations. Refer to the Q7740A,B FTTRep

3、eater Installation Instructions, form 95-7555, forinformation on enabling the on-board network terminators.FTT networks are very flexible and convenient forinstallation and maintenance. However it is imperative tocarefully plan the network layout, and create and maintain accurate layout documentatio

4、n.INSTALLATIONThe FTT/LPT Termination Module can be attached to thenetwork at a controller node (the easiest place; In a wallmodule that is attached to standard utility junction box (themodule will not fit in a 60 mm junction box; At a wiringjunction (using wire nuts. See Fig. 6 when connecting twow

5、ires at a controller or wall module terminal. If thetermination module must be located at a surface mountedwall module, and does not fit inside the wall modulehousing, extend a pair of E-Bus wires from the wall moduleback to the nearest junction box or controller, and wire inthe termination module.

6、The module has three lead wires,but only two are attached to the E-Bus network .To installthe termination module, connect the brown and yellowwires to the E-Bus when the network requires single termination ; connect the brown and orange to the E-Buswhen the network requires double termination. In ei

7、thercase, always cover the unused wire with a wire nut toprevent potential grounding problems. As with other E-Busconnections, polarity is not important.
