Table 5-19. Choke dimensions; Sizes 261A…1150A
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. Further-
more, 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 5-27.
