FIG. 60 Wire Termination for E-Bus Connection

1.Strip 1/2 in. (13 mm) insulation from the conductor.

3.If two or more wires are being inserted into one terminal location, twist the wires together a minimum of three turns before inserting them.

4.Cut the twisted end of the wires to 3/16 in. (5 mm) before inserting them into the terminal and tightening the screw.

5.Pull on each wire in all terminals to check for good mechanical connection.

Wire Requirements

The minimum type and grade of wire required to “network” the Intelli-Fin to other units or LonMark® devices is a Level IV, 22 AWG (0.034 mm2) plenum or non-plenum rated (as applicable), unshielded, twisted pair, stranded communication wire. The following manufacturers supply communication wire that meets or exceeds this specification for E-Bus connections.

(BICC Cable, Brand-Rex, General Cable, Carol Cable)

NOTE:

The minimum specification for Level IV, 22 AWG (0.034 mm2) unshielded, twisted pair, stranded communication cable must be plenum-rated when the wire is routed through air ducts or plenum areas. Non-plenum rated communication cable is for general use when the wire is not being routed through air ducts or plenum areas.

ADDITIONAL COMPONENTS

USED TO INTERFACE

MULTIPLE APPLIANCES

Serial LonTalk® Adapter (SLTA) — A serial LonTalk® adapter is required to provide communication between the E-Bus and either a PC serial port or an approved modem using the SLTA-10EIA-232 port. The SLTA interfaces with LonSpecTM software. There are specific null modem cable requirements for proper connection to a modem. The SLTA has a DB-9 female connection. Direct connection to a PC can be made with a DB-9 to DB-9 cable or a DB-9 to DB-25 cable, based on the available PC connection.

FTT Repeater — A repeater is available to increase the network wiring length in an E-Bus network. The repeater is designed to be installed in a standard field supplied 4 by 4 junction box.

Excel 15 — The Excel 15 Building Manager is a LonMark® compliant device that provides network management functions for the E-Bus in a Light Commercial Building Solutions System. The Excel 15 is compatible with the E-Bus and uses the free topology transceiver (FTT). Individual Excel 15 Controllers and Communicating Subbases distributed on the E-Bus perform specific HVAC equipment control. The Excel 15 monitors and controls both local and remote controller points. If E-Bus communications are interrupted, the Excel 15 is capable of stand-alone operation.
