3.1 Operator Devices
Your panel may be equipped with one or
several panel door mounted operator devices
which may include the following: through-
the-door, lockable, input device disconnect
handle; operator selector switches; indicator
lights; speed potentiometer,
3.1.1 Input Disconnect
The purpose of the panel mounted input
disconnect with through-the-door handle is to
provide a local, lockable method of removing
all AC input power from the panel and AF-600
FP and AF-650 GP drive.
If your panel includes a circuit breaker, in
addition to providing a manual method of
applying and removing AC input power from
the panel, the circuit breaker also provides
short circuit protection for the panel
components and the motor.
WARNING: Although input power is removed
from the drive in the “Off” position this does
not guarantee that dangerous voltage levels
are absent. The AF-600 FP and AF-650 GP
drives contain capacitors which can maintain
dangerous voltage levels for an extended
period following removal of AC input power.
Before touching any potentially live parts of
the frequency Drive, it is always advisable to
wait at least 20 minutes if not specified.
380-500V AF-650 GP drives
15 to 100HP wait at least 15 minutes
125 to 300HP wait at least 20 minutes
350HP and above, wait at least 40 minutes
525-690V AF-650 GP drives
50 to 400HP wait at least 20 minutes
500 and above, wait at least 30 minutes
Shorter time is allowed only if indicated on
the nameplate for the specific unit.
WARNING: Since an improper setting of the circuit
breaker trip level can result in code violations or
inadequate short circuit protection possibly
resulting in a fire or safety hazard, refer to the
“Adjustments” section of this manual for further
instructions on setting the trip level.
