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 2-20 and 2-21)
with bolts. The cables to the drive are bolted to the lower connectors. See Table 2-18 for
bolt sizes.
