modules in total may be installed with the LCP Rack
and LCP Inline devices. With the LCP Inline flush, up
to four fan modules may be installed (see section 16.2
"Characteristic curves").
5.3.1
Removing a fan module
If a fan module is defective, it can be replaced quickly
and easily with the unit operational.
Proceed as follows to remove a fan module:
Open the front door of the Liquid Cooling Package.
Disconnect the thermally activated switch for the
pair of fans from which one of the fans is to be re-
moved at the fuse box.

The following assignment applies between the ther-
mally activated switches and the fans:
– Thermally activated switch 1:
Fan positions 1 and 2
– Thermally activated switch 2:
Fan positions 3 and 4
– Thermally activated switch 3:
Fan positions 5 and 6
Configuration with LCP Rack and LCP Inline:
Should you wish to exchange fan 2 and if the option-
al display with touch function is installed, please first
disconnect connector X33 of the connection cable
(fig. 29, item 2).
Release the two fan connectors DC and AC on the
left and right (fig. 29, items 3 and 5).
Disconnect the earth connection on the fan (fig. 29,
item 4).
Loosen the two screws, right and left (fig. 29,
item 1), at the top and bottom of the fan mounting
plates.

Rotate the fan module in the rack by 90° in a clock-
wise direction (fig. 30).
Note:
If more than three fans are installed in a
Liquid Cooling Package type "30 kW", these
are used to create redundancy or for lower
power consumption by the individual fans.
However, they will not lead to a further in-
crease in the cooling output.
Note:
On the LCP Inline flush, thermally activated
switch 3 (fig. 28, item 3) is not assigned and
therefore has no function.
