TO MOUNT THE D20 TO A POLE
Similar to the instructions for mounting the D20 to a wall, attach the controller upright to a pole or pipe with a
diameter between 19 to 65 mm (0.75 to 2.5 in) that has either a vertical (L) or horizontal (R) orientation:
CONNECT ELECTRICAL CONNECTORS AND FITTINGS
At the bottom of the D20 enclosure are the electrical connectors and fittings for the instrument. To maintain the
enclosure’s environmental rating, ensure the following:
▪
Strain relief must have an electrical cable that is within its specified diameter range.
▪
Hole plugs should remain installed onto any unused connectors.
While the D20 controller doesn’t require “hard wiring” of connectors
, it offers the following connection options:
A 120V power*
B 2P conductor wire for alarm (optional)
C 5P conductor wire for liquid and flow sensor (optional)
D M12 4P connector for Halogen MP5 sensor
E
8P 4-20mA connection (optional)
F
120V power output for controlling pumps* (optional)
G 120V power output for controlling pumps* (optional)
H 120V power output for controlling pumps* (optional)
I
Communications board (BLE and cellular)
*240V available with 1/2" conduit
Warning:
Do not plug in the power cable to a power outlet yet!
