Low Voltage Supply Option
As an alternative, the Control Board can be powered directly with 24VAC or 24VDC. The ECU
may be equipped with a 24VAC plug-in transformer as the power supply.
ELECTRICAL INSTALLATION
Plug the Plug-in Transformer into the nearest 115V receptacle and connect the outbound wires
from the Plug-in Transformer to the Green and White “AC” wires of the “Power Harness”.
Polarity is not important. Verify the “POWER” LED is illuminated solid.. Follow local codes or
guidelines.
Solar Supply Option
! IMPORTANT: The number of cycles achieved daily is dependent on many factors, including
local solar radiation data and power consumption of the motor and accessories. It is very
important that you consider this when using solar power.
! Caution: The DC Power Supply Input at the Control board is Polarity Sensitive. If
supplying 24VDC directly to the Control Board, ensure correct DC polarity before
you apply this power supply to the Control Board.
24v AC 115v or 230v24v AC
! Caution: Always turn off power breakers when working with high voltage. DO NOT
connect the “Power Harness” to the Control Board until the electrical installation is
complete and ready for verification. To reduce the risk of electric shock, this equipment
(external plug-in transformer) has a grounding type Plug, that has a third (grounding) pin. This
plug will only t into a grounding type outlet. If the plug does not t into the outlet, contact a
qualied electrician to install the proper outlet. Do not change the plug in any way.
