WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

The unit cabinet must have an uninterrupted or unbroken ground to minimize personal injury if an electrical fault should occur. The ground may consist of electrical wire or metal conduit when installed in accordance with existing electrical codes.

Before performing service or maintenance, be sure main power switch is turned OFF.

CAUTION

All wiring and connections must comply with NEC, CEC, local codes.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in damage or improper operation.

Unit failure as a result of operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components.

Wrong wiring may cause a burn-out of some electrical parts.

Do not damage or scratch the conductive core or inner insulator of the power and inter-connecting wires when peeling them.
