AC Input Voltage
WARNING:
Failure to heed the following may result in injury or death.
The Digital Nano/Nano+ control center supply circuit must be protected by a ground-
fault circuit- interrupter (GFCI).
CAUTION:
Failure to heed the following may result in equipment damage.
The AC input cannot be provided by an ORP Controller.
The Digital Nano/Nano+ control center is typically provided input power either directly from a
GFCI breaker or from a timer or controller. Determine which is best for your application.
Although not required, ideally the pump and Digital Nano/Nano+ are controlled by the same
timer.
Connecting to an External Timer or Controller
1) Measure and cut
½” (13 mm) nonmetallic flexible conduit to reach from the power
source to the Digital Nano/Nano+.
2) Feed the wires from Digital Nano/Nano+ through the conduit.
3) At time clock or external controller relay, connect AC power wiring to the LOAD SIDE or
the same location as the circulation pump wires (pump connected to circuit breaker,
time clock or electronic controller).
4) Connect the ground wire to the ground of the power source.
8.6.3
Low Voltage Wiring
WARNING:
Failure to heed the following may result in permanent injury or death.
ELECTRICAL SHOCK HAZARD
– Turn off the electrical power to unit before
servicing.
Connecting the Cell Cable
1) The cell cable connector is keyed and must be aligned to connect properly. Line up the
cell cord and plug into the cell cord connector located on the bottom right of the Digital
Nano/Nano+ base plate.
2) The other end of the cell cable is connected to two (2) of the cells electrical terminals. A
red weather plug is placed in the unused contact hole.
Connecting the Tri-sensor Cable
1) The Tri-sensor cable is 12
’ long (3.6 m) and connects the Tri-sensor Assembly to the
Digital Nano/Nano+ Connect the white 6-pin connector to the mating receptacle located
on the base of the Digital Nano/Nano+.
