LON WIRING INSTRUCTIONS
Communications connections require that the
FMS-1650L units be connected with twisted
pair communication cable to each unit in the
network. The unique network address of each
FMS unit is set by a network management tool
like LONMAKER.
All wiring must be done in accordance with
the NEC as well as regulations of all authori-
ties having jurisdiction, and must conform to
applicable codes. When required by code, com-
munications wiring may be installed in conduit
of a type designed specifically for this purpose.
WIRE TERMINATIONS
The FMS-1650L is provided with a removable
connector block with convenient screw termi-
nals. Make the LON FTT-10 communications
connections as follows:
1 Connect a cable lead to the “NT1 -” terminal
(#1).
2 Connect a cable lead to the “NT2” terminal
(#2)
GUIDELINES FOR WIRING
Following these guidelines will help to keep
wiring-related communications problems to a
minimum:
1. Do not splice communications cable or wire
at any point.
2. Avoid “T-tap” technique of routing/connecting
communications cable. Conductor discontinui-
ties produced by such connections may gener-
ate RFI or other electromagnetic interference
on the communications circuit.
3. Do not use wire nut devices for connecting
communications cable.
4. Do not route any part of the communications
cable through conduit, junction boxes or other
devices containing AC electrical wiring.
5. Do not strap communications cable to any
conduit or other device containing AC electrical
wiring, or run communications cable parallel to
(or against) such devices.
NOTE: AC electrical devices such as transform-
ers, disconnects, fluorescent lighting, motor-
controllers, variable frequency drives or other
high voltage power sources may generate RF
interference which could cause intermittent
problems in the communications network.
