Grounding
See illustration on next page.
This equipment must be grounded to reduce the
risk of static sparking and electricshock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
