4.3 GROUNDING
WARNING
The unit must be permanently grounded. Failure to do so can result in electri-
cal shock causing personal injury or death.
• 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.
4.4 ELECTRICAL WIRING
POWER WIRING
• Field wiring must comply with the National Electrical Code (C.E.C. in Canada) and
any applicable local ordinance.
• Supply wiring must be 75°C minimum copper conductors only.
• See electrical data for product Ampacity rating and Circuit Protector requirement.
GROUNDING
• This product must be sufficiently grounded in accordance with National Electrical
Code (C.E.C. in Canada) and any applicable local ordinance.
• A grounding lug is provided.
