The VFD box must be installed outside and a safe distance
from the blade diameter for service purposes.
1. Verify voltage and phase before mounting. Ensure voltage
shown on VFD box is correct.
2. Mount VFD box outside the fan blade arc. Orient box
such that front panel is accessible and visible with the
connectors on top of the panel.
3. Route the fan S.O. cable from the fan to the VFD box.
Ensure the cable is supported throughout its routing. See
Fig 17.
4. Route supply power from the building source to the VFD
box.
5. Wire VFD box in accordance with electrical schematics
located on pages 26-30.

1. Mount touch screen remote to factory supplied junction
box inside building 60" above the floor as close to the fan
assembly as practical. Direct line of sight is preferred. See
Fig 17.
note:
Blue CAT5e cable has terminated ferrules at the remote end.
PROTECT these ferrules during cable routing.
2. Route the factory supplied blue cable 6015651 and the
gray cable (6011643) from the top of the VFD box, through
the hole in the factory supplied junction box shown in the
upper view of Fig. 17 and wire the 4 leads of the blue cable
to the orange connector of the touch screen remote control
as shown in the lower view of Fig 17. Coil approximately
6' of the gray cable in the junction box and secure. Excess
blue and gray cable length should be neatly coiled and
secured near VFD box.
