DESCRIPTION
The LMBC-300-H6 Quick Connect Wiring Harness provides BACnet connection for up to 6 LMBC-300s, mounted to a DIN rail. Each
end of the harness has the (S) Shield wire connected, while the connectors for each individual LMBC-300 have the (S) Shield wire
twisted and securely wrapped around the wire jacket with heat shrink. Since up to 40 LMBC-300s can be connected in a BACnet
segment, use of the LMBC-300-H6 allows for a minimum number of terminations in a properly wired BACnet network.
The harness contains 6 male terminal blocks for connection to LMBC-300s, plus a male terminal block on one end and female terminal
block on the other end. The harness also includes additional pre-attached male and female terminal blocks, for use when connecting to
LM-MSTP cable. Remove these terminal blocks to connect to another LMBC-300-H6.
Step 1 Remove Connectors from the LMBC-300s
Unscrew and unplug the connectors from each LMBC-300.
Attached
Connector
Step 2 Attach DIN Rail Mounting Bracket
Screw mounting bracket (included with LMBC-300) into
back of the LMBC-300.
Step 3 Attach LMBC-300s to DIN Rail
Attach up to 6 LMBC-300s to an 18” DIN rail, by
pulling spring-loaded handle and fitting clip into rail.
Step 4 Attach Harness Connectors to
LMBC-300s
Plug connectors on the LMBC-300-H6 into
each LMBC-300, securing each connector by
screwing it in.
NOTE: Do not connect the male terminal
block at the end of the harness to
an LMBC-300. This terminal block is
used only to extend the segment by
connecting to LM-MSTP cable or an
additional LMBC-300-H6, or to end the
segment by connecting to a terminal
block with an end-of-line resistor.
NOTE: If connecting fewer than 6 LMBC-300s
to the harness, place LMBC-300s at
both ends of the harness to prevent
slack in the middle, as shown in the
drawing on the next page.
Step 5 Connect BACnet Cable or Another Harness
If connecting the harness to LM-MSTP cable, attach the cable to the
extra male terminal block, as shown below. Repeat at the other end with
the extra female terminal block.
NOTE: Wattstopper recommends the use of ferrules to connect wires to
the terminal block, as described on the next page.
If connecting to another LMBC-300-H6, remove the appropriate extra
terminal block from each harness and connect the two.
If this harness is at the end of the segment, an EOL (End of Line)
120Ω resistor must be installed on the extra female terminal block, as
shown below.

Attaching Ferrules to LM-MSTP Wires
Wattstopper recommends attaching ferrules to the LM-MSTP wires to
help maintain signal integrity. Wires should be stripped as shown in the
diagram to the right. Insert the wire into a ferrule and crimp the end,
using a crimping tool designed to work with ferrules. Then insert the end
of the ferrule into the appropriate slot in the terminal block.
