SOLAR PANEL INSTALLATIONSOLAR PANEL INSTALLATION
For Viking Vehicular Gate Operators
STEP 1
Use a 24V solar panel or two solar panels of 12V
in series with a total capacity of 40 Watts..
STEP 3
Replace the existing batteries with a battery pack
of 33AHr or greater.
STEP 2
Connect the solar panel cables to the power
harness as shown. Make sure you cut the wires
coming from the toroidal transformer.
STEP 4
Refer to the maps provided to get an idea about the
number of cycles the gate will be operated per day.
This figure is for a single gate operator with just:
a) One Radio reiver,
b) One low voltage low current loop detector and
c) One low voltage, low current photo cell

NOTE –
1. Remember that the sun is your only source of energy.
2. The greater capacity of the batteries, the longer the system will operate on
cloudy days.
3. If more spcific information is needed, please consult with Viking Access Systems.
