Grounding; Connect Power Cord - Graco XM 24W626 Operation Manual

Grounding

The equipment must be grounded to reduce the risk
of static sparking and electric shock. All internal earth
grounding must use only copper wires. See electrical
schematics in systems repair manual for wire size.
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.
All components shipped from the factory are electrically
bonded through ground wires. Ground the electrical
connection properly according to local codes.

Power must be connected by a qualified electrician.
