LCX9000 Liquid-Cooled Drives User Manual

January 2007

If you have ordered the input chokes for the liquid-cooled drive separately, pay attention to the following instructions:

1.Protect the chokes from dripping water. You may even need to use plexiglass for protection because jets of water may occur when working with the connections.

2.Connection of cables:

Types CHK0023N6A0, CHK0038N6A0, CHK0062N6A0 (chokes with terminal blocks) The terminals are marked with letters U, V, W and X, Y and Z such that terminals U and X, V and Y as well as W and Z form pairs of which one is an input and the other an output. Furthermore, terminals U, V and W must all be used as either input or output. The same applies to terminals X, Y and Z. See Figure 2-19.

Example: If you connect the mains cable of one phase to terminal X, the other two phases must be connected to Y and Z. Accordingly, the choke output cables are connected to their corresponding input pairs: phase 1 U, phase 2 V and phase 3 W.

Other types (chokes with busbar connection)

Connect the mains cables to the upper busbar connectors (see Figures 2-20and 2-21) with bolts. The cables to the drive are bolted to the lower connectors. See Table 2-18for bolt sizes.
