Option Description Option
Type
K1 Door-Mounted Speed Potentiometer — Provides the CPX9000 with the ability to adjust the frequency reference using a door-
mounted potentiometer. This option uses the 10V DC reference to generate a 0 – 10V signal at the analog voltage input signal
terminal. When the HOA bypass option is added, the speed is controlled when the HOA switch is in the hand position. Without
the HOA bypass option, a 2-position switch (labeled local/remote) is provided on the keypad to select speed reference from the Speed
Potentiometer or a remote speed signal.
Control
K2 Door-Mounted Speed Potentiometer with HOA Selector Switch — Provides the CPX9000 with the ability to start/stop and adjust
the speed reference from door-mounted control devices or remotely from customer supplied inputs. In HAND position, the drive
will start and the speed is controlled by the door-mounted speed potentiometer. The drive will be disabled in the OFF position.
When AUTO is selected, the drive run and speed control commands are via user-supplied dry contact and 4 – 20 mA signal.
Control
K3 3 – 15 psig Follower — Provides a pneumatic transducer which converts a 3 – 15 psig pneumatic signal to either 0 – 8V DC or a
1 – 9V DC signal interface with the CPX9000. The circuit board is mounted on the inside of the front enclosure panel and connects
to the user’s pneumatic control system via 6 ft. (1.8m) of flexible tubing and a 1/4 inch (6.4 mm) brass tube union.
Control
K4 HAND/OFF/AUTO Switch for Non-bypass Configurations — Provides a three-position selector switch that allows the user to
select either a Hand or Auto mode of operation. Hand mode is defaulted to keypad operation, and Auto mode is defaulted to con-
trol from an external terminal source. These modes of operation can be configured via drive programming to allow for alternate
combinations of start and speed sources. Start and speed sources include Keypad, I/O and Fieldbus.
Control
K5 MANUAL/AUTO Speed Reference Switch — Provides door-mounted selector switch for Manual/Auto speed reference. Control
K6 START/STOP Pushbuttons — Provides door-mounted START and STOP pushbuttons for either bypass or non-bypass
configurations.
Control
KF Bypass Test Switch for RB and RA — Allows the user to energize the AF drive for testing while operating the motor on the
bypass controller. The Test Switch is mounted on the inside of the enclosure door.

KO Standard Elapsed Time Meter — Provides a door-mounted elapsed run time meter. Control
L1 Power On and Fault Power Lights — Provides a white power on light that indicates power to the enclosed cabinet and a red fault
light that indicates a drive fault has occurred.
Light
L2 Bypass Pilot Lights for RB, RA Bypass Options — A green light indicates when the motor is running in inverter mode and an
amber light indicates when the motor is running in bypass mode. The lights are mounted on the enclosure door, above the
switches.

LE Red Run Pilot Light (22 mm) — Provides a red run pilot light that indicates the drive is running. Light
P1 Input Circuit Breaker — High Interrupting Circuit Breaker that provides a means of short circuit protection for the power cables
between it and the CPX9000, and protection from high-level ground faults on the power cable. Allows a convenient means of dis-
connecting the CPX9000 from the line and the operating mechanism can be padlocked in the OFF position. This is factory mounted in
the enclosure. Standard rating is 65 KAIC at 208/480V. 100 KAIC is available as an option.
Input
PE Output Contactor — Provides a means for positive disconnection of the drive output from the motor terminals. The contactor
coil is controlled by the drive’s run or permissive logic. NC and NO auxiliary contacts rated at 10A, 600V AC are provided for cus-
tomer use. Bypass Options RB and RA include an Output Contactor as standard. This option includes a low VA 115V AC fused
Control Power Transformer and is factory mounted in the enclosure.
Output
PF Output Filter — Used to reduce the transient voltage (DV/DT) at the motor terminals. The Output Filter is recommended for cable
lengths exceeding 100 ft. (30m) with a drive of 3 hp and above, for cable lengths of 33 ft. (10m) with a drive of 2 hp and below, or
for a drive rated at 525 – 690V. This option is mounted in the enclosure, and may be used in conjunction with a Brake Chopper Circuit.
Output
PG MotoRx (300 – 600 Ft.) 1000 V/µS DV/DT Filter — Used to reduce transient voltage (DV/DT) and peak voltages at the motor termi-
nals. This option is comprised of a 0.5% line reactor, followed by capacitive filtering and an energy recovery/clamping circuit. Unlike the
Output Filter (See option PF), the MotoRx recovers most of the energy from the voltage peaks, resulting in a lower voltage drop
to the motor, and therefore conserving power. This option is used when the distance between a single motor and the drive is
300 – 600 feet (91 – 183m).
Output
PH Single Overload Relay — Uses a bimetallic overload relay to provide additional overload current protection to the motor on con-
figurations without bypass options. It is included with the Bypass Configurations for overload current protection in the bypass
mode. The Overload Relay is mounted within the enclosure, and is manually resettable. Heater pack included.
Output
PI Dual Overload Relays — This option is recommended when a single drive is operating 2 motors and overload current protection
is needed for each of the motors. The standard configuration includes two bimetallic overload relays, each sized to protect a
motor with 50% of the drive hp rating. For example, a 100 hp drive would include two overload relays sized to protect two 50 hp
motors. The relays are mounted within the enclosure, and are manually resettable. Heater packs not included.
Output
PN Dual Overloads for Bypass — This option is recommended when a single drive is operating 2 motors in the bypass mode and
overload current protection is needed for each of the motors. The standard configuration includes two bimetallic overload
relays, each sized to protect a motor with 50% of the drive hp rating. For example, a 100 hp drive would include two overload
relays sized to protect two 50 hp motors. The relays are mounted within the enclosure, and are manually resettable.
