Description of options
The dV/dt filter plus VPL consists of two components: the
dV/dt reactor and the VPL (Voltage Peak Limiter), which limits
voltage peaks and returns the energy to the DC link. It is
housed in an add-on options cabinet. Option L10 cannot be
combined with option M78 (Motor side top cable exit).
L13
Input contactor
The input contactor allows the drive to be connected to or be
disconnected from the input power supply in response to an
electrical control signal. The 120 V 1ph AC control supply for
the contactor is included.
L17
Feeder for external auxiliaries (line volts) 3ph. AC
An outgoing circuit fused at max. 10 A for external auxiliary
equipment (for example, a motor blower). The voltage is
tapped at the converter input and, therefore, has the same
level as the supply voltage. The circuit includes a motor
circuit protector (MCP) and a contactor (120 V coil) that
can be controlled internally by the drive or externally.
L22
Without input line reactor
If the drive is powered via a separate transformer, or if the
ratio between the line short circuit capacity at the point of
connection and the rated drive output is low, the input line
reactor may be omitted.
A 2% to 3% inductor primarily assures the minimum current
form factor, protects the drive against excessive harmonic
currents and thus overloads, and improves the sensitivity of
the VFD to voltage spikes. A minimum 2% input line reactor
is recommended for most installations.
L29
3 contactor bypass
The standard 3 contactor bypass circuit provides for the
motor to be switched from the drive to the bypass circuit,
in the event of a drive fault. Switchover to bypass or drive
operation is manual, as is starting the motor (directly across
the line (DOL start)). This option includes:
• Drive input and output isolation contactors
• Bypass contactor
• Mechanical interlocking of the drive output and bypass
contactors, in addition to electrical interlocking of all
three contactors.
• Electronic motor overload relay in the bypass circuit
• VFD – OFF – Bypass switch
• Bypass ON and OFF pushbuttons
• Pilot lights Bypass READY (green) and RUNNING (amber)
Automatic bypass operation and synchronized bypass for
bumpless switching of the motor to and from the line can
be offered as a custom option. Please consult factory.
L30
Soft start bypass
The soft start bypass option also provides for the motor
to be switched from the drive to the bypass circuit, in
the event of a drive fault. Switchover to bypass or drive
operation is manual, as is starting the motor, in this case
with an electronic reduced voltage soft starter (RVSS).
This option includes:
• Drive input and output isolation contactors
• RVSS input and output isolation contactors
• Mechanical interlocking of the drive and RVSS output
contactors, in addition to electrical interlocking of all
four contactors
• Siemens type 3RW44 RVSS including internal bypass
contactor, and electronic motor overload protection
• VFD – OFF – Bypass switch
• Bypass ON, OFF and RESET pushbuttons
• Pilot lights Bypass READY (green), RUNNING (amber)
and FAULT (red)
Automatic bypass operation can be offered as a custom
option. Please consult factory.
L50
Enclosure light with power outlet 120 V, 1 ph AC, 5 A
One universal light with an integrated service socket (3 pin
US style) is installed in the line connection cabinet of the
drive as well as in the add-on options cabinet (if applicable).
The light is switched manually. This option requires an
external power source.
L55
Enclosure space heater
Space heaters are recommended at low ambient tempera-
tures and high levels of humidity to prevent condensation.
One 90 W heater is provided for each cabinet >32” (800 mm)
width. For cabinets exceeding this width, two heaters will be
installed. This option requires an external power source.
L61
Braking unit 100 kW (for 460 V, 150 and 200 HP only)\
L62
Braking unit 200 kW (for 460 V, 250 to 800 HP, and 575 V)
The braking unit comprises two components: a braking
module mounted inside the drive power module, and a
braking resistor (supplied loose) that must be mounted
separately (IP20). The braking unit functions as an
autonomous unit and does not require an external power
supply. During the braking process the kinetic energy is
converted into heat in the external braking resistor. A cable
length from braking module to braking resistor up to 150 ft
is permissible, allowing the heat to be released outside the
drive room. The braking resistor is connected to terminal
block -X5 in the drive unit:
