Grounding Requirements
In the event of certain types of malfunctions or
breakdowns, grounding provides a path of least
resistance for electric current—in order to reduce
the risk of electric shock.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power until
instructed later in this manual.
