Step 5 After mounting and wiring the inverter,
remove any covers from the inverter hous-
ing. This includes material over the side ven-
tilation ports.
!WARNING Make sure the input power to the inverter is
OFF. If the drive has been powered, leave it
OFF for ten minutes before continuing.

NOTE:
For the wiring of intelligent
I/O and analog inputs,
be sure to use twisted
pair / shielded cable.
Attach the shielded wire
for each signal to its
respective common
terminal at the inverter
end only.
