8.7 ELECTRICAL

CAUTION - Failure to heed the following may result in equipment damage.

8.7.1 Electrical Connections

A High voltage AC input provides power to the control center. Low voltage cables provide power from
the control center to the Tri-Sensor and cell.
The AC input voltage of the Digital Nano/Nano + has been preconfigured at the factory.

Model numbers 75040, 75040-xx, 75042, and 75042-xx have been configured for 115 Vac.

Model numbers 75041, 75041-xx, 75043 and 75043-xx have been factory configured for 230 Vac.
These voltage configurations can be changed in the field by a qualified electrician if required.
1) Refer to the wiring diagram located on the inside of the power center cover to reconfigure
the wires on the terminal block if the unit AC input voltage is going to be changed.
2) The fuse must be changed if the AC input is changed from the factory shipped
configuration::

230 Vac units require a 1 amp slow blow fuse.

115 Vac units require a 2 amp slow blow fuse.

8.7.2 AC Input Voltage

WARNING - Failure to heed the following may result in injury or death.
CAUTION - Failure to heed the following may result in equipment damage.
The Digital Nano/Nano + is typically provided input power either directly from a GFCI breaker or from a
timer or controller. Determine which is best for your application. (Note: The 75040, 75042, 75040-xx
and 75042-xx come supplied with an attached 115 Vac cable and can be connected into a time clock
or 115 Vac GFCI outlet.) Although not required, ideally the pump and Digital Nano/Nano + are
controlled by the same timer. SEE WARNING AND CAUTION ABOVE.

8.7.3 Low Voltage Wiring

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 feet long (3.4m) and connects
the Tri-Sensor Assembly to the Control Center.
2. Connect the white 6-pin connector to the mating plug
located on the base of the Digital Nano/Nano + .
3. Position the directional tab forward in relation to water flow.
Connecting 230Vac to a unit that has been configured to 115 Vac will result in
permanent damage to the unit. Damage due to incorrect wiring is not covered
under the warranty.
The Digital Nano/Nano + supply circuit must be protected by a ground-fault
circuit-interrupter (GFCI).
The AC input cannot be provided by an ORP Controller.
