What is operator side?
When picking an operator side you are choosing where the manual override is (left or right side). So be mindful of where you would want the manual override to be on your awning once it is installed. You are also choosing which side the cable for the motor will come out of the awning. See photo below for reference:
Example: If you have two awnings next to each other you may want to option the first awning with the operator side on the right and the other awning on the left. This allowing the awnings to be wired side by side at one outlet rather than possibly needing to install two separate outlets. See picture below for a visual explanation:
