Low Voltage Supply Option
TIP:
As an alternative to high voltage, the operator can be power 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.
ELECTRICAL INSTALLATION
Install the “Modular Power Box” at the nearest high voltage source (115V or 230V single
phase AC) and connect to the operator 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. (See page 46 for package details)
Disconnect the operators
power harness and use the
Solar Harness.
Connect the two
panels in series.
Connect the batteries
in series.

MAXIMUM DISTANCE:
500 ft. with 10 AWG wire
! Tip: Solar efficiency can be increased
by activating the “Pre-Warning”
feature. The “Aux. Pwr” terminals
will then provide power to all
nonessential controls beginning 3
seconds prior to gate movement and
while the gate is moving. (page 25)

! 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.
