CONNECTIONS
Please refer to the connection diagram in
Appendix A
of this manual.
The anemometer and AC adapter (200-WS-21P, sold separately) are supplied with connectors that fit the
¼" spade terminals on the Wind Alarm circuit board. Extra connectors are provided for connecting an
earth ground and alarm relay connections. You will need a crimp tool or heavy duty pliers to make these
connections. You will also need to provide insulated wire. Stranded wire of 14 – 16 gage is preferred.

7.1
Anemometer Connection
Route the anemometer cable through the gland fitting and into the case. Connect the earth ground
connector with the tab facing down, to make room for the other connections. Attach the red and black
wires as indicated on the drawing.
Prepare a suitable length wire with a standard wire connector, and connect it to the lug on the earth
ground connector. Route the other end of this wire to a good earth ground – an electrical box with an
earth connection or a metal cold water pipe that actually enters the ground. Failure to provide a ground
may cause erratic operation and make the system more vulnerable to damage from nearby lightning
strikes
.
7.2
Power Connection
Route the wiring from the AC Adapter or other power supply through the cable gland and attach the
positive terminal (marked with red shrink wrap or a white stripe on one lead) to the ACin / DCin terminal.
Connect the ground wire to the ACin / DCgnd terminal. The power input accepts 12 volts AC or DC.
We recommend connecting the AC Adapter to an outlet with a surge suppressor. Power strips with surge
suppressors are often used to protect computer equipment and are readily available.
It is good practice to program the set points and delays, and then operate the system using the visible LEDs
and buzzer as alarm indicators, before connecting the relays to your external equipment. Recheck your
connections to make sure there are no stray wires that could cause a short circuit.
Plug in your power supply. The green power LED should turn on and the word "Wind:" will be displayed. If
you see the word "Temp:" instead of "Wind:" then the DIP switches are in the wrong position. Refer to the
"DIP Switch Settings" section of the manual to correct this situation.
