Important: For each installed instrument, allow for the appropriate cable
length necessary to reach the FanMaster I/O terminals in the
enclosure. Refer to
Wiring Specifications on page 2-2 for
control wire size.
4. Wire the supply air temperature transmitter according to the
manufacturer’s instructions, route through the appropriate conduit (if
used) and connect the control wires to terminals 100, 102, 123 and 124
on TB2 in the FanMaster enclosure.
5. Wire the mixed air temperature transmitter according to the
manufacturer’s instructions, route through the appropriate conduit (if
used) and connect the control wires to terminals 100, 102, 125 and 126
on TB2 in the FanMaster enclosure.
6. Wire the CO
2
sensor according to the manufacturer’s instructions, route
through the appropriate conduit (if used) and connect the control wires
to terminals 100, 102, 127 and 128 on TB2 in the FanMaster enclosure.
7. Wire the damper position indicator switch according to the
manufacturer’s instructions, route through the appropriate conduit (if
used) and connect the control wires to terminals 100 and 105 on TB2 in
the FanMaster enclosure.
8. If you are installing an evaluation unit, connect the control wires for the
supply fan current switch to terminals 100 and 109 on TB2 in the
FanMaster enclosure.
9. For FanMaster evaluation unit installations, continue with step 24 on
page 2-18 . For installations with a drive complete the appropriate steps:
– PowerFlex 400 Drive (below)
– PowerFlex 70EC, 700VC or 753 Drive on page 2-13
PowerFlex 400 Drive
Important: A 120 Ohm terminating resistor (provided with the drive)
must be connected to pins 4 and 5 of the RJ45
two-position terminal block adapter on the return air
drive. If a return air drive is not installed, the terminating
resistor must be connected to pins 4 and 5 of the RJ45
terminal block on the supply air drive. Refer to
Figure
B.8 on page B-9 for details.
Important: The communication cable maximum length should not
exceed 500 m (1,640 ft).
a. Wire the RJ45 terminal block adapter and terminating resistor to
TB3 in the FanMaster enclosure and connect it to the PowerFlex
400 drive.
b. Continue with step 10 on page 2-14 .
