5. Connect the cables:
● For chassis CH5 and greater, an external flexible cable connection block must be
used at both mains and motor ends if stiff cable type (EMCMK, MCMK) is used. See
Page 3-1.
● Strip the cables at a sufficient distance if needed.
● Connect the mains, motor and control cables to their respective terminals (see
Chapter 2). If busbar connection is used, bolt the bars and the terminals together.
See bolt sizes on Pages 2-2 to 2-11.
● Also take the maximum terminal stresses shown in Figure 3-1 into account.
● For information on cable installation according to UL regulations see Page 3-13.
● Make sure that the control cable wires do not come in contact with the electronic
components of the unit.
● If an external brake resistor (option) is used, connect its cable to the appropriate
terminal (CH3 only).
● Check the connection of the ground cable to the motor and the drive terminals
marked with .
● Connect the separate shield of the power cable to the ground terminals of the drive,
motor and the supply center.
6. Liquid cooling connection:
The standard delivery of the LCX9000 Liquid-Cooled drive includes hoses on the cooling
element 4.9 feet (1.5m) in length and .59 inches (15 mm) in diameter. The hoses are
inserted in 55 inch (1400 mm) UL94V0 approved conduits. Connect the line hose branch
to its counterpart (screw or fast connector) of the Cutler-Hammer Liquid-Cooled drive.
Due to high pressure in the line hose, equipping the liquid line with a shut-off valve is
recommended, which makes the connection easier. In order to prevent water from
spraying in the installation room we also recommend wrapping e.g. linters around the
connection during installation. For more information on the liquid connection, see Page
2-18.
When the installation in the enclosure is completed, the liquid pump can be started. See
Start-Up of the drive in Chapter 6.
Note: Do not switch on the power before ensuring proper function of the liquid cooling
system.
