Maxax YX-450 Operating instructions

I've reviewed the user manual for the YX-450 light. This document provides detailed safety warnings, installation instructions, a parts list, and a wiring diagram to help you set it up correctly and safely. This Manual also contains very important information about risks connected with electric supply and health risks. I am ready to answer your questions about this product.
What should I do before installing the light?

Is it recommended that I install the light myself?

What should I do after touching the light?
