1. Strip 1/2 in. (13 mm) in su la tion from the conductor.
2. Insert the wire in the required terminal location
and tighten the screw to complete the termination.
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 “net work” the
Intelli-Fin to other units or LonMark
® devices is a Level IV,
22 AWG (0.034 mm 2 ) plenum or non-plenum rated (as applicable),
unshielded, twisted pair, stranded com mu ni ca tion wire. The
following man u fac tur ers supply com mu ni ca tion wire that meets or
exceeds this specification for E-Bus connections.

NOTE:
The minimum specification for Level IV, 22 AWG
(0.034 mm
2 ) 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-10 EIA-232 port. The SLTA interfaces with LonSpec
TM
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.
