LCX9000 Liquid-Cooled Drives User Manual
Grounding and Ground Fault Protection
The LCX9000 drive must always be grounded with a ground conductor connected to the
ground terminal.
The ground fault protection inside the drive only protects the drive against ground faults in
the motor or the motor cable. It is not intended for personal safety.
Due to the high capacity currents present in the drive, fault current protective switches may
not function properly.
Motor and Equipment Safety
Before starting the motor, check that the motor is mounted properly
and ensure that the machine connected to the motor allows the
motor to be started.
CAUTION
January 2007
CAUTION
Set the maximum motor speed (frequency) according to the motor
and the machine connected to it.
CAUTION
Before reversing the motor, make sure that this can be done safely.
CAUTION
Make sure that no power correction capacitors are connected to the
motor cable.
CAUTION
Make sure that the motor terminals are not connected to mains
potential.
CAUTION
Before the Liquid-Cooled drive can be used to control the motor,
the proper functioning of the liquid-cooling system must be
ensured.

Storage and Shipping
If the drive is to be kept in storage before use, make sure that the ambient conditions are
acceptable:
Storing temperature-40 – 158°F (-40 – 70°C) (no cooling liquid inside cooling element
allowed below 0º)
Relative humidity<96%, no condensation
If the storage time exceeds 12 months, the electrolytic DC capacitors need to be charged with
caution. Therefore, such a long storage time is not recommended.
Maintenance
In normal conditions, Cutler-Hammer Liquid-Cooled drives are maintenance-free. However, if
the drive is used in conditions with temperatures below the freezing point and the liquid used
for cooling is likely to freeze, be sure to empty the cooling element if the drive must be moved or if it is taken out of use for a longer time.
LCX9000 Liquid-Cooled Drives User Manual
CAUTION
Always remove all cooling agent from the cooling element(s)
before shipping to avoid damage caused by freezing.
It may also be necessary to clean up the coolant ducts in the cooling element. Contact the
factory for more information.
The instructions for the cooling system provided by its manufacturer must be followed.
Technical Data
Figure 1-1 presents the block diagram of the liquid-cooled drive. Mechanically, the product
consists of two units, the Power Unit and the Control Unit. The power unit can contain one to
six modules (cooling plates), depending on the drive size. Instead of air, liquid-cooled drives
use liquid for cooling. A charging circuit is embodied in the drives.
An external three-phase AC-choke (1) at the mains input together with the DC-link capacitor
(2) form an LC-filter. In drives, the LC-filter together with the diode bridge produce the
DC-voltage supply to the IGBT Inverter Bridge (3) block. The AC-choke also functions as a
filter against High Frequency disturbances from the mains as well as against those caused by
the drive to the mains. In addition, it enhances the waveform of the input current to the drive.
In chassis with multiple parallel line-rectifiers (CH74) AC-chokes are required to balance the
line current between the rectifiers.
The power drawn by the drive from the mains is mostly active power.
The IGBT Inverter Bridge produces a symmetrical, three-phase Pulse Width Modulated
AC-voltage to the motor.

LCX9000 Liquid-Cooled Drives User Manual
The Motor and Application Control Block is based on microprocessor software. The
microprocessor controls the motor based on the information it receives through
measurements, parameter settings, control I/O and control keypad. The motor and
application control block controls the motor control ASIC which, in turn, calculates the IGBT
positions. Gate drivers amplify these signals for driving the IGBT inverter.
The control keypad constitutes a link between the user and the drive. The control keypad is
used for parameter setting, reading status data and giving control commands. It is
detachable and can be operated externally and connected via a cable to the drive. Instead of
the control keypad, a PC can also be used to control the drive if connected through a similar
cable (±12V).
You can have your drive equipped with a control I/O board which is either isolated (OPT-A8)
or not isolated (OPT-A9) from the frame. Optional I/O expander boards that increase the
number of inputs and outputs to be used are also available. For more information, contact
Eaton or your local distributor.
The basic control interface and the parameters (the Basic Application) are easy to use. If a
more versatile interface or parameters are required, a more suitable application can be
chosen from the application manual.
An internal brake chopper is available as standard for chassis CH3. For all other sizes the
brake chopper is available as an option and installed externally. The standard product does
not include a brake resistor. It should be ordered separately.

Liquid-cooled drive modules must be installed into an enclosure. The drives consisting of
one module will be mounted on the mounting plate. The drives that include two or three
modules are mounted inside a mounting bracket, which will then be installed in the
enclosure.
Note: If any other than vertical installation position is required, please contact your
distributor!
On Page 2-2 you will find the dimensions of liquid-cooled drives installed on mounting bases
(plates and brackets).
Lifting the Drive
Eaton recommends use of a jib crane or similar elevating device to lift the drive unit. See
Figure 2-1 for correct lifting points.
Use either the hole(s) in the middle of the mounting plate (Lifting point 1) or the hole in the
H-shaped part of the mounting plate (Lifting point 2) for lifting the drive. See Figure 2-1.

Cooling
Instead of using air for cooling, Cutler-Hammer Liquid-Cooled drives are cooled with liquid.
The liquid circulation of the drive is usually connected to a heat-exchanger (liquid-liquid/
liquid-air) which cools down the liquid circulating in the cooling elements of the drive. The
cooling agents acceptable for use are drinking water, demineralized water or a mixture
(60/40) of water and glycol. In a closed circulation system, the values in Table 2-3 are
recommended reference values. To avoid electrochemical corrosion, Eaton recommends
adding an inhibitor (e.g. Ferrolix 332/Henkel or Cortec VpCI-649) in the cooling agent.
Note:
If no heat-exchanger is used, actions must be taken to avoid electrochemical corrosion.
Specifically no brass or copper elements may be used in the liquid circulation of the drive.
Drinking Water Specification
Table 2-3 provides general guidelines for water quality.
Note: 1 mg/L = 1 ppm.
