1. Mark the shielded cable from FM1 to FC1 at Motor-
master® V controller location. The cable will be cut at
this point, so be sure to allow enough slack to reach the
Motormaster V controller and fuse block.
2. In the area marked, cut the cover off of the cable. Cut
each individual wire and mark both ends for identifica-
tion. Mark wires 1, 2 and 3.
3. Strip the ends of the wires coming from FC-1, and attach
them to one side of the fuse block.
4. Install the 10-in. black, yellow and blue wires from the
fuse block to the Motormaster V terminal block (L1, L2
and L3). The BLK, YEL, and BLU wires are on the same
fuse as wires 1, 2 and 3, and are on Motormaster V termi-
nals L1, L2 and L3, respectively.
5. Install the other end of the cut wires (on the FM side)
into the Motormaster V terminal block T1, T2 and T3
terminals.
6. Ground shield with the ground wire from each side of the
cut shielded cable.
7. Remove wires from FC-1, T1/T2/T3 and connect at FU1
(or TB1 if FU1 not used).
8. Attach the sensor cable to the pressure transducer and
route it to the controller. Ensure that the cable is separated
from all sharp edges. Trim the lengths of the cable as
desired, but ensure that shield drain wire is used.
9. Attach the RED, GRN and BLK wires from the sensor
cables to the Motormaster V control terminal block posi-
tions 6, 5 and 2, respectively. Attach shield drain wire to
the panel where the Motomaster V is mounted.
10. Attach VIO and the RED wires from FR-1 fan relay
terminals 5 and 9 to Motormaster control. The RED wire
connects at terminals 2, the VIO wire to the terminal listed
in Table 8. Repeat for circuit B using VIO and RED wires.
11. Attach GRA and the RED wires to FR-1 terminals 13 and
14. Attach the other ends to FC-1 terminals C1 and C2.
Repeat for circuit B using VIO and RED wires.

terminals T1, T2, T3 respectively. Re-attach ground wire
to control box back wall using ground screw punch near
Motormaster V controller.
5. Install 40-in. BLK, YEL, BLU wires from fan circuit
breaker FCB-1 to fuse block MMF-A. Install 38-in. BLK,
YEL, BLU wires from MMF-A to input power terminals
L1, L2, L3 respectively on MM-A.
6. Install 40-in. BLK, YEL, BLU wires from fan circuit
breaker FCB-2 (or FCB-1 is 2 is not used) FC-A1 to fuse
block MMF-B. Install 38-in. BLK, YEL, BLU wires
from MMF-B to input power terminals L1, L2, L3
respectively on MM-B.
7. Attach sensor cables to pressure transducers and route
cable to control box. Ensure that the cable is separated
from sharp edges. Route cable through knockouts in
bottom of control box. Seal cable to control box using
supplied varnish cloth and metal conduit connector. Wrap
varnish cloth around wires to separate wires from metal
connector. Trim lengths of cable as desired but ensure that
shield drain wire is used.
8. Attach RED, GRN, BLK wires from sensor cables to
Motormaster controls terminal block 6, 5 and 2 respec-
tively, see Fig. 1 and 26. Attach shield drain wire to con-
trol box near Motormaster control using the original
ground screw.
9. Attach VIO and the RED wires from FR-1 fan relay
terminals 5 and 9 to Motormaster control. The RED wire
connects at terminals 2, the VIO wire to the terminal listed
in Table 8. Repeat for circuit B using VIO and RED wires.
10. Attach GRA and the RED wires to FR-1 terminals 13 and
14. Attach the other ends to FC-1 terminals C1 and C2.
Repeat for circuit B using VIO and RED wires.
