Cable Installation Instructions

1.Before starting the installation, check that none of the components of the drive is live.

2.LCX9000 Liquid-Cooled drive must always be installed in an enclosure, a separate cubicle or an electrical room.

Always use a jib crane or similar lifting device to lift the drive. For safe and appropriate lifting, see Page 2-1.

3.Place the motor cables far enough from other cables:

●Avoid placing the motor cables in long parallel lines with other cables.

●If the motor cables run in parallel with other cables, note the minimum distances between the motor cables and other cables given in table below.

●The given distances also apply between the motor cables and signal cables of other systems.

Distance between	Shielded
Parallel Running	Cable
Cables in Feet (m)	in Feet (m)
10 (.3)	≤164	(50)
3.3 (1.0)	≤656	(200)

●The maximum length of the motor cables is 984 feet (300m).

●The motor cables should cross other cables at an angle of 90 degrees.

4.If cable insulation checks are needed, see Page 3-11.

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 2-7.

●Also take the maximum terminal stresses shown in Figure 3-1into account.

●For information on cable installation according to UL regulations see Page 3-10.

●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.
