BAC-9300 Series Controller Installation Guide 4 925-019-02G

CONNECT POWER

NOTE: Follow all local regulations and wiring

codes.

1. Connect a 24 VAC, Class-2 transformer to the

black power terminal block of the controller.

A. Connect the neutral side of the transformer

to the controllers common terminal

⊥

B. Connect the AC phase side of the

transformer to the controllers phase

terminal

∼

NOTE: Connect only one controller to each

transformer with 12—24 AWG copper

wire.

NOTE: Use either shielded connecting cables

or enclose all cables in conduit to

maintain RF emissions specications.

NOTE: For more information, see Sample

(BAC-9311) Wiring on page 7 and the

YouTube video KMC Conquest Wiring:

BAC-9300 Series Unitary Controllers.

POWER AND COMMUNICATION STATUS

The status LEDs indicate power connection and

network communication. The descriptions below

describe their activity during normal operation (at

least 5 to 20 seconds after power-up/initialization

or restart).

NOTE: If both the green READY LED and the

amber COMM LED remain OFF, check

the power and cable connections to the

controller.

CONNECT (OPTIONAL) MS/TP NETWORK

1. For BAC-93x1/93x1C models (only), connect

the BACnet network to the gray BACnet MS/

TP terminal block

NOTE: Use 18 gauge AWG shielded twisted

pair cable with maximum capacitance

of 51 picofarads per foot (0.3 meters)

for all network wiring (Belden cable

#82760 or equivalent).

A. Connect the –A terminals in parallel with

all other –A terminals on the network.

B. Connect the +B terminals in parallel with all

other +B terminals on the network.

C. Connect the shields of the cable together

at each device using a wire nut or the S

terminal in KMC BACnet controllers.

2. Connect the cable shield to a good earth

ground at one end only.

NOTE: For principles and good practices

when connecting an MS/TP network,

see Planning BACnet Networks

(Application Note AN0404A).

NOTE: The EOL switch is shipped from the

factory in the OFF position.

3. If the controller is at either end of a BACnet

MS/TP network (only one wire under the

terminals), turn the EOL switch

to ON.
