Installation
InspectionInspect the carton for damage. If damaged, notify the carrier immediately. Inspect controllers
for damage upon receipt.
Requirements
(These items not provided)
• Installer must be a qualified technician
• Job wiring diagrams
• Tools:
– Digital Volt-ohm meter (DVM)
– Drill and bits for mounting screw
– Static protection wrist strap
• MNA-FLO-1 enclosure for connecting to conduit (optional)
• Class 2 power transformer supplying a nominal 24 Vac (20.4 to 30 Vac) with a minimum
rating of 12 VA, 50/60 Hz per controller, plus Digital Output (DO) and Triac loads. Each
DO can be up to an a
maximum. In the European Community, trans
dditional 24 VA maximum and each Triac load an additional 18 VA
former must conform to EN 60742
• Terminators:
– One LON-TERM1 terminator is required for each free topology segment
– Two LON-TERM2 terminators is required for each bus topology segment
• Two #10 sheet metal screws
• 0.170 in. (17/100 in.) I.D. FRPE polyethylene tubing or 0.125 in. (1/8 in.) I.D. or 0.25 in.
(1/4 in.) O.D. Tygon™ tubing for piping connections. Not more than 5 ft (1.52 m) long.
• Communication wire pairs must be dedicated to MN-Sx (S-Link) and MicroNet
LONWORKS network (LON) communications. They cannot be part of an active, bundled
telephone trunk.
• Shielded cable is not required for S-Link or LON wiring.
• If the cable is installed in areas of high RFI or EMI, the cable must be in conduit.
• If shielded wire is used, the shield must be connected to earth ground, at one end only,
by a 470K ohm, 1/4 watt resistor. Shield must be continuous from one end o
to the other.
Communications wiring includes a connection between the controller and a TAC I/A Series
MicroNet Sensor via the S-Link and a connection between the controller and the MicroNet
ONWORKS Network (LON). An optional LON connection between the controller and one
L
TAC I/A Series MicroNet Sensor is also possible. Figure-4 shows S-Link and LON wiring
terminations.
Sensor Link (S-Link) Wiring
S-Link wiring powers and enables the MN-Sx sensor. The S-Link needs at least 24 gage
(0.205 mm2), twisted pair, voice grade telephone wire. The capacitance between conductors
cannot be more than 32 pF per foot (0.3 m). If shielded cable is used, the capacitance
between any one co

Note:
• Controller supports one TAC I/A Series MicroNet Sensor (MN-Sx).
• S-Link wiring is polarity insensitive.
• If conduit is used between a TAC I/A Series Sensor and a controller, the MicroNet
LONWORKS network and S-Link wiring can be in the same conduit. However, the LON
and S-Link wiring must use separate cables.
• S-Link wiring (not LON wiring) can be in the same conduit with UI, AO, and DI Wiring.
MicroNet LONWORKS Network (LON) Wiring
An approved Category 4 or 5, twisted-pair (two conductors) cable may be used for
connecting to both the MicroNet LONWORKS Network and the optional LONWORKS Network
connection between the controller and an MN-Sx sensor. L
polarity insensitive.
Caution: Do not mix with UI, DI, AO, DO, or power types of wiring. If conduit is used
between a TAC I/A Series Sensor and a controller, LON wiring and S-Link wiring can be in
the same conduit. However, the LON and S-Link wiring must use separate cables.
MNL-V3RVx controllers use the LONWORKS Free Topology Transceiver FT 3150 and
support polarity-insensitive bus (daisy-chain) and free-wiring topologies (all combinations of
star, tee, and loop). A maximum of 62 nodes can be connected per segment.
Note: The FT 3150 transceiver used in the MNL-V3RVx controller is fully compatible with
the TP/FT-10 channel, allowing it to communicate with I/A Series MicroNet controllers that
use the FTT-10 tran

topologies and approved cable types.
sceiver. See TAC I/A Series MicroNet System Engineering Guide,
ONWORKS Network wiring is
• Use of the LON terminals to connect to the MN-Sx sensor permits use of the sensor’s
built-in LON jack.
• To preserve the integrity of the network, the LON wiring connecting an I/A Series
MicroNet controller to an MN-Sx sensor must be run to the sensor and back, in daisychain fashion. A wire “spur” must not be used to connect the sensor to the controller.
• While the MN-Sx sensor is not counted as a “node” in the LONWORKS network (LON),
all LON wiring to the sensor must be counted when determining the length of the FTT
wiring segment.
I/O connections include universal inputs, analog outputs, digital inputs, and digital outputs
(relay and triac outputs). See Figure-4 for proper wire terminal information.
Caution: If shielded wire is used, connect only one end of the shield to earth ground, at
the controller.
Universal Inputs (UI), Analog Outputs (AO), and Digital Inputs (DI)
Caution:
• Input and output devices cannot share common wiring. Each connected device requires
a separate signal and return conductor.
• Power wiring cannot share conduit with UI, AO, S-Link, LON, or DI wiring.
Note:
• If maximum closed switch voltage is not more than 1.0 V and minimum open switch
voltage is at least 4.5 V, then solid state switches may be used for a UI or a DI.
• UI, AO, DI, and S-Link wiring can share a single conduit.
UI, AO, DI, wiring needs at least 24 gage (0.205 mm2), twisted pair, voice grade telephone
wire. The capacitance between conductors cannot be more than 32 pF per foot (0.3 m). If
shielded cable is used, the capacitance between any one conductor and the others,
connected to the shield, cannot be more than 60 pF per foot (0.3 m).
