If you have ordered the input chokes for VACON
®
NX Liquid-Cooled 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 in such an order, however,
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 33.
