SECTION 8
Wiring the Fan
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT SERVICE
PANEL BEFORE STARTING INSTALLATION.
CAUTION:
ALL ELECTRICAL CONNECTIONS MUST BE MADE
IN ACCORDANCE WITH LOCAL CODES, ORDINANCES, OR NATIONAL
ELECTRICAL CODE. IF YOU ARE UNFAMILIAR WITH METHODS OF
INSTALLING ELECTRICAL WIRING, SECURE THE SERVICES OF A
QUALIFIED ELECTRICIAN.
1. Remove the screws securing the terminal box cover plate located on
the side of the motor
(Figure 9).
2. Run wiring from an approved wall switch carrying the appropriate rating.
One neutral (white) and one hot (black lead connected to the switch).
Secure the electrical wires to the housing with an approved electrical
connector. Make sure you leave enough wiring in the terminal box to
make the connections to the fan’s pre-wired electrical terminal strip.
3. Insert the white wire from the house into the terminal strip port labeled
“N” and tighten using a small regular screwdriver. Insert the black wire
from the wall switch into the terminal strip port labeled “L” and tighten
using a small regular screwdriver. Since the motor is isolated within a
plastic housing, grounding is not necessary
(Figure 10).
4. Check to make sure all wire connections are securely fastened to the
terminal strip and replace the fan terminal box cover.
5. Restore power and test your installation.
