Option Description Option Type
RA Manual HOA Bypass Controller — The Manual HAND/OFF/AUTO (HOA) — 3-contactor — bypass option provides a means of
bypassing the CPX9000, allowing the AC motor to be operated at full speed directly from the AC supply line. This option consists
of an input disconnect, a fused control power transformer, and a full voltage bypass starter with a door mounted HOA selector
switch and an INVERTER/BYPASS switch. The HOA switch provides the ability to start and stop the drive in the inverter mode.
For applications up to 250 hp, an IT. Series IEC input contactor, an IT. Series IEC output contactor, and an IT. Series IEC starter
with an electronic overload relay is included. For applications above 250 hp, an Advantage input contactor, an Advantage output
contactor and an Advantage starter with electronic overload protection is included. The contactors are mechanically and electri-
cally interlocked (see power diagram on Page 40-261).
Bypass
RB Manual IOB Bypass Controller — The Manual INVERTER/OFF/BYPASS (IOB) — 3-contactor — bypass option provides a means of
bypassing the CPX9000, allowing the AC motor to be operated at full speed directly from the AC supply line. This option consists
of an input disconnect, a fused control power transformer, and a full voltage bypass starter with a door mounted IOB selector
switch. For applications up to 250 hp, an IT. Series IEC input contactor, an IT. Series IEC output contactor, and an IT. Series IEC
starter with an electronic overload relay is included. For applications above 250 hp, an Advantage input contactor, an Advantage
output contactor and an Advantage starter with electronic overload protection is included. The contactors are mechanically and
electrically interlocked (see power diagram on Page 40-261).
Bypass
RC Auto Transfer HOA Bypass Controller – The Manual HAND/OFF/AUTO (HOA) — 3-contactor — bypass option provides a means
of bypassing the CPX9000, allowing the AC motor to be operated at full speed directly from the AC supply line. The circuitry pro-
vides an automatic transfer of the load to “across the line” operation after a drive trip. This option consists of an input discon-
nect, a fused control power transformer, and a full voltage bypass starter with a door mounted HOA selector switch and an
INVERTER/BYPASS switch. The HOA switch provides the ability to start and stop the drive in either mode. For applications up to
250 hp, an IT. Series IEC input contactor, an IT. Series IEC output contactor, and an IT. Series IEC starter with an electronic overload
relay is included. For applications above 250 hp, an Advantage input contactor, an Advantage output contactor and an Advantage
starter with electronic overload protection is included. The contactors are mechanically and electrically interlocked (see power
diagram on Page 40-261). Door mounted pilot lights are provided which indicate bypass or inverter operation. A green light indi-
cates when the motor is running in inverter mode and an amber light indicates when the motor is running in bypass mode.
WARNING: The motor may restart when the overcurrent relay is reset when operating in bypass, unless the IOB selector switch
is turned to the OFF position.
Bypass
RD Auto Transfer IOB Bypass Controller — The Auto INVERTER/OFF/BYPASS (IOB) — 3-contactor — bypass option provides a means
of bypassing the CPX9000, allowing the AC motor to be operated at full speed directly from the AC supply line. The circuitry pro-
vides an automatic transfer of the load to “across the line” operation after a drive trip. This option consists of an input discon-
nect, a fused control power transformer, and a full voltage bypass starter with a door mounted IOB selector switch. For
applications up to 250 hp, an IT. Series IEC input contactor, an IT. Series IEC output contactor, and an IT. Series IEC starter with an
electronic overload relay is included. For applications above 250 hp, an Advantage input contactor, an Advantage output contac-
tor and an Advantage starter with electronic overload protection is included. The contactors are mechanically and electrically
interlocked (see power diagram on Page 40-261). Door mounted pilot lights are provided which indicate bypass or inverter oper-
ation. A green light indicates when the motor is running in inverter mode and an amber light indicates when the motor is run-
ning in bypass mode.
WARNING: The motor may restart when the overcurrent relay is reset when operating in bypass, unless the IOB selector switch
is turned to the OFF position.
Bypass
RG Reduced Voltage Starter for Bypass — Used in conjunction with bypass option RA, RB, RC or RD. This option adds IT. Series
reduced voltage soft starter to bypass assembly for soft starting in bypass mode.
Bypass
S7 10" Expansion — Expansion cabinet allows for special components, customer-supplied components or oversized cables.
NOTE: Enclosure expansion rated NEMA Type 1 only.
Enclosure
S8 20" Expansion — Expansion cabinet allows for special components, customer-supplied components or oversized cables.
NOTE: Enclosure expansion rated NEMA Type 1 only.
Enclosure
S9 Space Heater — Prevents condensation from forming in the enclosure when the drive is inactive or in storage. Includes a
thermostat for variable temperature control. The 400W heater requires a customer supplied 115V remote supply source.
