Network Wiring Requirements:
•Use stranded CAT5e or higher shielded cable.
•Minimum 24AWH (0.5mm) cross section.
•Ground the shielding and drain wire at only one point of the cable run.
•Route wires as far away as possible from high voltage AC cables, fluorescent lights, arc
welders, and other equipment that transmits EMI (electromagnetic interference).
•Do not run CAT5e in conduit with high voltage AC cables.
•Do not exceed 400ft [122m] of CAT5e between each fan in the network.
Daisy Chain
Network MacroAir fans must be connected in one single line, referred to in this document as a
“daisy chain”. The characteristics of a proper daisy chain are: one beginning (Controller 4) and
one end (last fan or control panel).
If the fans are not connected in
one line/chain, there will be a
degradation of the communication
signal and the network may not
function as intended (fans in the
network may not operate).
Each fan has a unique address,
which is noted on a sticker on the
fan itself (AVD 370) or control
panel (AVD3, 550, 780, Y and X
Series Fans). It is important to
mount the fans in the correct
order.

Network Wiring Configurations cont.
Excess Cable at Connection Point
With noise being emitted throughout a typical industrial/commercial environment, extra cable
should not be coiled up as the coil itself will create noise/interference in the communication
signal. There should be no more than 2ft [0.6m] of excess cable at each connection point.
If more than 2ft [0.6m] of cable is needed for future relocation of the fan, run the cable up
toward the ceiling and back down in a horseshoe shape.
ALWAYS AVOID SHARP BENDS OF THE CABLE.

AVD 370 RJ45 Wiring Instructions
AVD 370 fans with RJ45 ports on the board are wired in T-splices. Each T-splice will consist of 3
CAT5e cables. A properly wired T-splice network is shown below:

Controller 4 Operation Manual 90-30027-00 Rev A-01 Date: 032720
T-Splice Connection Method for AVD 370 Fans
1. Take the incoming CAT5e from the
network, the 15ft [4.57m] CAT5e whip
from the fan, and the CAT5e going to
the rest of the network. Give some slack
(no more than 2ft / 0.6m) on each
CAT5e to strip the wires and splice them
together. Run the slack up towards the
ceiling and back down in a horseshoe
shape.
DO NOT roll the excess slack into a circle or coil because this creates a place for the
network to pick up noise on the lines.
2. Strip jacketing off the three CAT5e
cables and separate each color wire
leaving approximately 2in [5cm] of each
wire exposed including the drain/shield
wire.
3. Strip approximately 1/2in [1.3 cm] off
each color wire leaving the bare copper
exposed.
4. Twist the 3 wires of same color from
each CAT5e together.

5. Place a gel filled bean crimp onto the end
of the three (3) wires and use a small
crimper or pliers to crimp the bean tight
on the wires.
6. Double check that the three (3) drain
wire/bare wires are also crimped together
as this is what continues the shielding
throughout the network. The shielding
and drain wire MUST be connected to
Earth Ground at only one point of the
cable run.
7. Repeat steps 3-5 for all the wires.
8. Once all the wires are crimped, carefully
twist the wires up. Then fold them back
and tape them up with electrical tape to
clean up your wiring.
