1- W4B-120C Description
The W4B-120C is a technically advanced wind charger. It includes DC diversion charge
control, so user has to install the diversion load with it.
The manual will help you to become familiar with the W4B-120C’s features and capabilities.
Some of these follow:
• LCD meter with easy to read messages.
• DIP switch to set up the wind charger for its intended use. All major functions can be
set with DIP switches.
• Rated for 12, 24, 48 voltage systems and 120 amps current.
• Eight standard charging with DIP switches.
• Continuous self-testing with fault notification
• LED indications and pushbutton functions.
1.1 Versions and Ratings
W4B-120C-120 (WS-120C):
• Rated for maximum 120 amps continuous current
• Rated for 12, 24, 48 Voltage DC systems
• Diversion Load (optional)
1.2 Operating
The W4B-120C will manage battery charging by 3-phase wind turbine from the battery to a
dedicated diversion load.
1.3 Adjustability
Eight DIP switches permit the following parameters to be adjusted at the installation site:
1.4 General Use

• The W4B-120C is configured for negative ground systems. There are no parts in the
wind charger’s negative leg. The enclosure can be grounded using the ground termi-
nal in the wiring compartment.
• There are fuses or mechanical parts inside the W4B-120C to reset or change.
The W4B-120C is rated for indoor use. The wind charger is protected by conformal
coated circuit boards, stainless steel hardware, anodized aluminum, and a powder
coated enclosure, but it is not rated for corrosive environments or water entry.
• The construction of the W4B-120C is 100% solid state.
With bulk charging, absorption, float and equalization stages.
• The W4B-120C will accurately measure time over long intervals to manage events
such as automatic equalizations or battery service notification.
• LED’s, a pushbutton, and LCD meters provide both status information and various
manual operations.

2- W4B-120C Installation
The installation instructions describe wind battery charging.
2.1 General Information
The mounting location is important to the performance and operating life of the wind char-
ger. The environment must be dry and protected as noted below. The wind charger may
be installed in a ventilated enclosure with sealed batteries, but never in a sealed battery
enclosure or with vented batteries.
2.2 Installation Overview
The installation is straightforward, but it is important that each step is done correctly and
safely. A mistake can lead to dangerous voltage and current levels. Be sure to carefully fo-
llow each instruction in Section 2.3 and observe all cautions and warnings.
The following diagrams provide an overview of the connections and the proper order:

2.3 Control Terminal Connection
Install the counter with Collector 1 and Collector 2 by yourself and then you will know the wind speed of the Wind Turbine (rpm). The
output of the Collector 1 and 2 is the Wind Generator Output Frequency.
2.4 Installation Steps
The W4B-120C wind charger must be installed properly and in accordance with the local and
national electrical codes. It is also important that the installation be done safely, correctly and
completely to realize all the benefits that the W4B-120C can provide for your wind system.
Before starting the installation, review these safety notes:
• Do not exceed a battery voltage of 48V (nominal). Do not use a battery less than 12V.
• Charge only 12, 24, or 48 volt lead-acid batteries when using the standard battery chargin-
gprograms or NI-CAD batteries when DIP switch number 4~6 is ON position in the W4B-
120C.
• Verify the nominal charging voltage is the same as the nominal battery voltage.
• Do not install a W4B-120C in a sealed compartment with batteries.

• Never open the W4B-120C access cover unless both the wind turbine and battery
power has been disconnected.
• Never allow the Wind Turbine to be connected to the W4B-120C with the battery and
Diversion load disconnected. This can be a dangerous condition with high voltage
present at the terminals.
2.4.1 Mounting
Mounting Dimensions
• Locate the W4B-120C on a wall protected from direct sun, high temperatures, and
water. Do not install in a confined area where battery
gasses can accumulate.
• When mounting the W4B-120C, make sure the air flow
around the controller and heat sink is not obstructed.
There should be open space above and below the heat
sink, and at least 75 mm (3 inches) clearance around the
heat sink to allow free air flow for cooling.
• Before starting the installation, place the W4B-120C on
the wall where it will be mounted and determine where
the wires will enter the controller.

2.4.2 Diversion Charge Control DIP Switch Settings
The 8 DIP switches are located on the top of the PE terminal. Each switch is numbe-
red. The wind battery charging functions that can be adjusted with the DIP switches
follow:
DIP Switch Functions
As shown in the diagram, all the positions are in the “OFF” position except switch
number 3 and 7 which are in the “ON” position.
NOTE: The DIP switches should be changed only when there is no power to the wind char-
ger. Turn off disconnect switches and remove all power to the wind charger before chan-
ging a DIP switch. A fault will be indicated if a switch is changed while the wind charger is
powered.
CAUTION 1: The W4B-120C is shipped with all the switches in the “OFF” position. Each
switch position must be confirmed during installation. A wrong setting could cause damage
to the battery or other system components.
CAUTION 2: To change a switch from OFF to ON, slide the switch up toward the top of the
wind charger. Make sure each switch is fully in the ON or OFF position.
CAUTION 3: DIP Switch Number 1 and Number 8 are always in the OFF position.
DIP Switch Number 1 and Number 8: Always in the OFF position
