This manual covers basic industrial GroWeather/EnviroMonitor installation,
including how to connect your sensors to the sensor interface module (SIM)
and how to power your unit. Instructions on installing/mounting sensors and
other system components (such as the Alarm Output Module) are contained in
the manuals for those products. This manual does include several installation
drawings which depict typical GroWeather/EnviroMonitor installations and
should help you connect all of your components correctly.

THE
We have provided two sheets of labels which should aid you in your installation. The majority of the labels on the sheets are cable labels for marking the
ends of each cable. These labels contain connector codes which will help you
attach the correct cable to the correct connector. We have included two label
sheets so you can label both ends of each cable with the same label.
To simplify installation, we have coded each connector and included the code
on the cable label and on the circuit board or enclosure next to the appropriate
connector. Most connector codes include a letter and a number. The letter identifies the module or unit on which the connector is located while the number
identifies the specific connector. The following letter codes identify the module/unit on which a connector is located.

Labelling the Cables
Any installation is going to include a number of cables running from various
sensors and components to other components. To alleviate confusion, we have
included label sheets which you should use to mark your cables. Before you
begin installation (but after you have cut each cable to the desired length), lay
out all of your cables and attach the appropriate label to each end of each cable.
Make sure you label every cable end, including extension cables.
now will help prevent confusion during the installation and whenever you
need to disconnect a sensor/component.

Doing this
Mounting the Sensor Interface Module
When labeling cables, orient the label so the connector code nearest the end of
the cable matches the connector to which that end of the cable will be attached.
For example, place one C2/SENSOR I’FACE/S7 label onto the 8-conductor
cable (which will be running between the sensor interface module (SIM) and
the console) so the C2 side of the label is nearest the end of the cable which will
be connected to the console. Place the second C2/SENSOR I’FACE/S7 label
onto the other end of the cable so the S7 side of the label is closest to the SIM
end of the cable.

You may mount the SIM on a wall or other vertical surface or you may simply
set it down on a horizontal surface. It should be sheltered from weather and
located near a grounding point. You may use our Complete System Shelter
(#7724) or Multi-Purpose Shelter (#7728) to provide protection from weather.
Use our Grounding Kit (#7780) if suitable ground is not otherwise available.

2. If you plan to mount the SIM against a wall or other vertical surface, attach the base
to the mounting surface using the #6 x 1” screws. Otherwise skip this step.
Use two screws (as shown below) when attaching to a stud. Use three
screws (as shown below) in any other case. Drill pilot holes using a #36

Make sure that you install your sensors and run all necessary cables to the SIM
location before connecting cables to the SIM.
Connecting to the Terminal Blocks
The industrial GroWeather/EnviroMonitor uses terminal blocks containing
high-reliability stainless steel spring-loaded cage clamps. You will be placing
one or two wires into each terminal in order to make the connection. First strip
about 1” (2.5 cm) of the jacket (the grey outer covering) and shield (the foil-like
inner covering) off the cable. Then strip about 5/16” (8 mm) of the insulation
(the colored outer covering) off each wire in the cable. Finally, use a small
screwdriver to push down on the lever next to the terminal, insert the exposed
wire into the opening created, and release the lever. If inserting two wires into
a single terminal, twist the two wires together before inserting. When you
release the lever, the wire(s) will be held in place by the cage clamp.

Connecting to the Sensor Interface Module
1. Attach one end of the 8-conductor cable (which runs from the SIM to the console) to
connector S7.
If using the provided 8-conductor cable to connect the SIM with the console
or the Interface Cable Adapter Module (ICAM), use the modular
connector S7. If using shielded 8-conductor cable to connect the SIM with
the ICAM (you cannot connect shielded cable to the console), connect each
of the wires in your shielded 8-conductor cable to the appropriate terminal
at the terminal block connector S7. Connect the drain wire to the terminal
with the triangle next to it.

colors printed on the circuit board.

nects to the terminal with the triangle next to it.
When using an extension cable, any extra conductors which are not

used at the sensor cable-to-extension cable connection should be
clipped off to avoid problems at any subsequent connections.
✦
When two color codes are listed together, it indicates that two wires
should be used as a single wire. Twist both wires together before
inserting into the terminal.
✦
Color codes in parenthesis indicate any additional wire color assignments for extension cables . If using an extension cable to connect to
the SIM, twist both listed wires together before inserting into the terminal. If connecting to the SIM with the sensor cable, ignore the
color code in parenthesis.

3. Connect the spade lug on one of the ground wires to the Shield Ground terminal and
the spade lug on the other ground wire to the Circuit Ground terminal. You will need
to connect the ground wires to a suitable ground after you finish installation.
Attaching the ground wire to the Shield Ground terminal is optional,
though it does allow you to take advantage of the SIM’s RFI and surge suppression capabilities. However, you
must
attach the ground wire to the Cir-
cuit Ground terminal.

Routing Cables out of Sensor Interface Module
1. Gather the cables connected on the left of the SIM (including the ground wire) and
secure them to the cable tie lug using a cable tie.
Even if you have only one cable, secure it to provide strain relief. When
tightening the cable tie, make sure the cables are on top of the lug.

3. Finally, reattach the cover by putting the cover into place (as shown below) and pushing it onto the base until the tabs on top of the cover snap back into their slots.
Make sure the cables run out the bottom of the SIM as shown below.

ONNECTING THE CONSOLE
In order to connect the cables to the console, you must remove the mounting
base which comes attached to the console. To remove the mounting base, press
down on the large tab until it is free from its slot and pull the base away from
the console. To connect the console to the SIM (or the ICAM), run the 8-conductor cable to the console and plug it into the jack marked C2 (To Sensor I’face) on
the underside of the console.
Primary Power
The console is powered by 9- to 12-volt DC (direct current). In North America,
the power adapter included with your unit converts 120-volt, 60-Hz AC (alternating current) to 9–volt DC, allowing you to run the unit on ordinary household current. If you are outside North America, in a location where the line
voltage is not 120–volt, 60–Hz, check to see if your local dealer has supplied a
power adapter that is appropriate for your electrical power before you connect
the power adapter to the console. If not, you must use a power converter/
transformer or the appropriate power adapter (9-12-volt, 2.5-mm female plug).
To power the console, simply connect the power adapter to the jack marked
C1 (Power) on the underside of the console. Plug the other end of the power
adapter into an appropriate power outlet. Once connected, the console should
run through a brief self-test procedure. All of the display segments appear, and
the console beeps twice (three times if you have the WeatherLink hardware
module attached). When the self-test finishes, the time (reading 12:00 a.m.)
appears on the display.
