CONNECT BATTERIES
33AH BATTERIES
The batteries are charged in the circuit by the integrated transformer. The batteries are for battery backup or solar installation. The 33AH application
requires the 33AH wire harness (Model K94-37236) and an additional battery tray (Model K10-36183) to allow more space in the enclosure. The
heater option cannot be used with the 33AH battery application.
1. Locate the J15 plug on the control board and disconnect it.
2. Connect the white jumper from the 33AH wire harness kit between the positive (+) terminal of one battery and the negative (-) terminal of the other
battery.
3. Connect one end of the red (+) wire from the 33AH wire harness kit to the red wire from the J15 plug as shown. Connect the other end of the red
(+) wire to the positive (+) terminal on the battery as shown.
4. Connect one end of the black (-) wire from the 33AH wire harness kit to the black wire from the J15 plug as shown. Connect the other end of the
black (-) wire to the negative (-) terminal on the battery as shown.
5. Turn ON AC power to the operator.
