Step 1 – Shipment Inventory and Supplies:
The Guardian-Carmanah (GCR) is shipped as a metal enclosure that contains a mounted Guardian
circuit board.Already connected to the mounted Guardian circuit board should be a modem harness
(connected to J1), an 8-pin Carmanah wiring harness (connected to J2) and a 10-pin Carmanah
wiring harness (connected to J3). An optional addition to the GCR is a door switch that if purchased,
comes prewired to J4 of the Guardian board.
Shipped along with the board and enclosure is an AP22-Carmanah wiring harness, two 10/32
phillips-head mounting screws, three male molex connectors, three female molex connectors, six
male wire pins, and six female wire pins.
IMPORTANT! The Guardian-Carmanah system requires the use of an RTC AP22 time clock and M2M
cell modem. If you purchased a new AP22 and cell modem with your GCR, you should see them
mounted inside your GCR enclosure. If you did not purchase AP22/modem products along with your
GCR and are not using existing RTC AP22/modem products, please contact RTC Manufacturing to
order.
Along with the product inventory above, you will need the following tools:
•MagneticPhillips-headscrewdriver •Wirecutters
•Wirestrippersfor18AWG •Pincrimpersfor18AWG(not wire crimpers)
Step 2 – Disconnect Power and Components
To prevent harm to product and self, safely disconnect the battery connections and power
to the system before touching any other components.
After the batteries have been disconnected, locate the wires coming from the white Carmanah unit
for batteries, solar panel 1, switch 1, switch 2, 12V DC, LED1, LED2 and LED3. Label both sides of
all connections, if not already done.Then, disconnect all wire connectors. If you do not see wire
connectors for the LEDs, but instead see solid gray wires going from the white Carmanah unit
down into the pole, do not cut or disconnect until told to do so in Step 6/Step 6B.
Step 3 – Mount and Connect AP22 and M2M
Please Note: Step 3 must be followed only if you are using existing AP22 and cell modem
equipment. If you are installing a GCR with new AP22 and cell modem hardware, the
connections below should already be made. Read the following step to confirm the connections
before proceeding.
Disconnect and remove all existing AP22 and cell modem hardware, wiring, and mounting materials
from the cabinet.
Connect the round end of the new AP22 wiring harness (shipped with your GCR order) to the base of
the AP22.
Mount the cell modem to the top of the AP22 using the modem mount.
Using the modem harness (connected to J1 on Guardian board), connect the round power cable to
the power connector on the cell modem. Connect the DB9 connector labeled “modem” to the DB9
connection on the modem. Finally, connect the other DB9 connector labeled “time switch” to the DB9
connection at the top of the AP22.
Mount the AP22 to the GCR enclosure in the proper location using the screw on the enclosure and
the slotted mounting hole on the back of the AP22.
Step 4 - Mount the Guardian-Carmanah Enclosure to the Cabinet
Unscrew the thumbscrews to the plexiglass cover. Using the Phillips-head screw driver and the
provided screws, secure the GCR enclosure to the cabinet by turning the screws through the enclosure
holes and into the two cabinet mounting holes above the left-side battery.The GCR enclosure is
designed to be installed with the AP22 on the left side of the cabinet and the Guardian board on the
right, with the wiring harnesses protruding into the middle of the cabinet. Replace plexiglass cover
once mounting is complete, with the white wire protector facing the top left corner.
Step 5 - Connect the Guardian Board to the
White Carmanah Unit and the AP22 Time Switch
Locate the J2 and J3 wiring harnesses on the Guardian board. Both harnesses consist of wires that
have been labeled and have a white male or female molex connector at the end.The labels and
gender connectors correspond with component wiring (either new or disconnected in Step 2) that
have labels and opposite-gender connectors.
Use the labels and gender connectors to make the following component connections:
• J2 wiring harness: (> symbol = connect to)
— SOLAR LID > unlabeled connector coming from lid of solar panel cabinet
— SOLAR PNL 1 > SOLAR PNL 1 (coming from white Carmanah unit)
— 12V DC > 12V DC (coming from white Carmanah unit)
— 12V DC AP22 > 12V DC AP22 (coming from the AP22 wiring harness)
• J3 wiring harness: (> symbol = connect to)
— J3 AP22 > J3 AP22 (coming from the AP22 wiring harness)
— SWITCH 2 > SWITCH 2 (coming from white Carmanah unit)
Step 6 - Connect LEDs
Locate the grey wires that are coming from the white Carmanah unit. These wires connect directly to
the LEDs.
In most Carmanah installations, you should find female molex connectors at the ends of the two or
three gray wires coming from the white Carmanah unit and two or three male molex connectors at the
ends of the gray wires coming from out of the pole. If this is the case, make the following connections
using the connectors from the J3 wiring harness:
• J3 wiring harness: (> symbol = connect to)
— LED1 (male) > LED 1 (female) coming from white Carmanah unit
— LED2 (male) > LED 2 (female) coming from white Carmanah unit
— LED3* (male) > LED 3 (female) coming from white Carmanah unit
*Some installations only feature two LEDs. If this is the case, disregard steps
mentioning LED3.
— LED1 (female) > LED 1 (male) coming from white Carmanah unit
— LED2 (female) > LED 2 (male) coming from white Carmanah unit
— LED3* (female) > LED 3 (male) coming from white Carmanah unit
Please Note: If you do not see component connectors for the LEDs and instead see solid gray
wires going from the white Carmanah unit down into the pole, follow Step 6 B.
Step 6B – Creating LED Connectors
If the gray LED wires running from the white Carmanah unit down into the pole are solid and do not
contain connectors, carefully follow these steps to create LED connectors:
1. Gently pull on gray wires to see if you can easily get the molex connectors in the pole to
come back into the cabinet. If you can, go back to Step 6 and follow the steps. If not,
continue below.
2. Cut one gray LED wire approximately 6 inches from the end that terminates at the white
Carmanah unit.
3. Strip the gray insulation around the internal conductors approximately 1.5 inches back
from both sides of the cut LED wire.
4. Strip the black and red wires approximately 3/16" back on both sides of the cut LED wire.
5. Using pin crimpers, attach the provided male pins to the stripped ends of the black and
red wires that are coming from the gray LED wire that ends at the white Carmanah unit.
See visual reference on back panel.
6. Using pin crimpers, attach the provided female pins to the stripped ends of the black and
red wires that are coming from the gray LED wire that goes down into the pole. See visual
reference on back panel.
7. Place and push the male pins into a white female molex connector.The pin on the black
wire should go into the hole on the side with the hinge on the end of the molex connector
and the pin on the red wire should go into the other hole. See visual reference on back
panel.
8. Place and push the female pins into a white male molex connector.The pin on the black
wire should go into the hole on the side with the connector clip and the pin on the red wire
should go into the other hole. See visual reference on back panel.
9. Repeat Steps 1-8 for each solid gray LED wire in the cabinet
