HIGH
VOLTAGE
DANGER
!
Always disconnect electrical power
at the fuse box or circuit breaker before handling
electrical connections. Double check to be sure
Power is OFF, and that it cannot be turned on while
you are working on the equipment.
WARNING
!
Make sure the unit is electrically
grounded and proper electrical installation wiring and
controls are used consistent with local and national electric
codes. Refer to “National Electrical Code Handbook” &
NFPA No. 70. Employ qualied electricians. Insulate all
connections carefully to prevent grounding or short
circuits. Reinstall all conduit and terminal box covers.
CAUTION
!
To connect power to the motor/control
unit, refer to the connection diagram on the nameplate.
AC line power is connected via the motor/control conduit
box terminal board only.
WARNING
!
Insulate all connections carefully to
prevent grounding or short circuits. Reinstall all conduit
and terminal box covers! Do not force connections into
the conduit
!
A poor electrical connection can overheat
and cause terminal and/or terminal board failures.
Because of this possibility, wiring harness quick-connect
terminals should be regularly examined carefully for any
signs of physical deterioration or loose t to the terminals
on the motor/control terminal board. If there is evidence of
loose t or deterioration, quick-connect terminals should
be removed from the wiring harness and the harness
wires then connected directly to the motor/control terminal
board wiring terminals. Care shall be taken to ensure
connections are made to the proper terminals and that
adequate electrical clearances are maintained.
