Introduction
The Whisper 100 Wind Generator and Controller must be configured for the correct system voltage - 12, 24, 36 or 48
volts. Whisper Wind Generators and Controllers are shipped from the factory configured for 24 volt operation unless
specially ordered.
To check the Wind Generator voltage configuration or to change the voltage, refer to the following notes and wiring
table. Your Whisper Dealer may also be of assistance configuring your Wind Generator to the voltage for your applica-
tion if different from 24 volts.
To check the Controller voltage setting or to change the voltage setting, refer to Sections 8, 9 and 10 for instructions.
Wiring and Assembly Notes
The correct Whisper 100 voltage is set by altering the 12 stator wire and 3 brush wire connections. The wire connec-
tions are made using appropriate size wire nut connectors.
To access the wires remove the metal “Multi Voltage” cover on the side of the Whisper turbine housing. Refer to the
following Voltage Configuration Wiring Table for specific stator and brush wire connections.
Observe the following notes when changing the voltage configuration:
•
The three brush wires are interchangeable and are not labeled. The brush wires are easily identifiable as they are
larger multi-strand wires and stator wires are solid wire. ( 8 awg compared to 20 awg).
•
Stator wires are numbered and color coded with a wire sleeve. For example stator wire “Red 3” has a red sleeve
with the number “3” printed on it. Wire “Red - “ has a red sleeve with no number. The “-” indicates there is no
number. There is a” Red - “, “White - “, and “Black -” stator wire.
•
When changing the voltage configuration cut off the twisted ends of the wires (stator wires only) and strip off ap-
proximately 25mm (1 inch) of insulation.
Important Note:
In addition to the PVC insulation, the stator wires are also coated with varnish that MUST be removed to make a good
connection. The varnish can be removed by scraping with sharp edge or lightly sandpapering the wire.
•
Hold the stripped ends of the wires to be joined parallel to each other and twist together with pliers before installing
the wire nut. The wires should be twisted in a clockwise direction.
•
Cut of the “untwisted” ends of the wires and twist on the appropriate color wire nut. Push hard on the wire nut
while twisting clockwise.
•
Coat wire nuts and terminal strip connections with dielectric grease to protect wires against corrosion. A tube of
dielectric grease is supplied with each Whisper 100.
