Table 40-334. Available Control/Communications Options (Continued)
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 DRIVE, 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
electrically interlocked (see power diagram on Page 40-239).
Bypass
RB Manual IOB Bypass Controller — The Manual INVERTER/OFF/BYPASS (IOB) — 3-contactor — bypass option provides a means of
bypassing the DRIVE, 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 40-239).
Bypass
RC Auto Transfer HOA Bypass Controller – The Manual HAND/OFF/AUTO (HOA) — 3-contactor — bypass option provides a means
of bypassing the DRIVE, allowing the AC motor to be operated at full speed directly from the AC supply line. The circuitry
provides an automatic transfer of the load to “across the line” operation after a drive trip. 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 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 40-239). Door mounted pilot lights are provided which indicate bypass or inverter operation. 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.
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 DRIVE, allowing the AC motor to be operated at full speed directly from the AC supply line. The circuitry
provides an automatic transfer of the load to “across the line” operation after a drive trip. 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 40-239). Door mounted pilot lights are provided which indicate bypass or
inverter operation. 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.
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
S4 Floor Stand 6" — Raises “E” box off the ground 6" (152.4 mm). Recommended when box is not installed on an appropriate
concrete pad.
Enclosure
S5 Floor Stand 22" — Converts a Size B or C, normally wall mounted enclosure to a floor standing enclosure with a height of
22" (558.8 mm).
Enclosure
S6 Floor Stand 12" — Converts a Size C, normally wall mounted enclosure to a floor standing enclosure with a height of 12" (304.8 mm). 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. Heater requires a customer supplied 115V remote supply source.
