This equipment is powered by three-phase alternating current,
as specified on the machine serial tag and data plate.
A properly sized conductive ground wire from the incoming power
supply must be connected to the chassis ground terminal inside the
electrical enclosure (control center). Improper grounding can result in
severe personal injury and erratic machine operation.
Always disconnect and lock out the incoming main power source before
opening the control center or performing non-standard operating proce-
dures, such as routine maintenance. Only qualified personnel should
perform troubleshooting procedures that require access to the control
center while power is on.
