ELECTRICAL INSTALLATION - STANDARD ECU
Low Voltage Supply Option
TIP:
As an alternative to high voltage, the operator can be powered by 24VAC. It is
recommended to use Vikings Modular Power Box (part # VNXMPB) as the source.
! 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.
Install the "Modular Power Box" at the nearest high voltage source (115V or 230V single
phase) and connect to the controller's Power Harness. Follow local codes or guidelines.
Solar Supply Option
Vikings Solar Package (part # VA-SOCHP) is an efficient and effective solution to
powering the operator with solar energy.
!
Tip:
Solar efficiency can be increased
by activating the "Pre-Warning"
feature. The "Aux. Pwr"
will provide 24VDC to all nonessential
controls, beginning 3 seconds prior to
gate movement, until the gate reaches
either limit. (page 25)

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.
