4.5 GROUNDING
• Grounding may be accomplished by grounding metal conduit when installed in accor-
dance with electrical codes to the unit cabinet.
• Grounding may also be accomplished by attaching ground wire(s) to ground lug(s)
provided in the unit wiring compartment.
• Ground lug(s) are located close to wire entrance on left side of unit (upflow). Lug(s)
may be moved to marked locations near wire entrance on right side of unit (upflow), if
alternate location is more convenient.
• Use of multiple supply circuits require grounding of each circuit to lug(s) provided in
unit.

The unit must be permanently grounded. Failure to do so can result in electri-
cal shock causing personal injury or death.
