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.
