A fan module is essentially comprised of the fan itself. All
fan modules are controlled via a joint control unit mount-
ed in the electronics box in the upper section of the
LCP DX. Fans may be operated with linear control be-
tween 30% and 100%.
The fan modules are installed on rack-mounted shelves
in the front section of the LCP DX.
It takes approximately 2 minutes to replace a single fan
module with the system operational (see section 9.3
"Fan installation").

Proper and improper usage
The LCP DX is used to dissipate high heat losses and ef-
fectively cool devices built into a server enclosure. The
unit is designed solely for static use in sealed rooms.
The unit is state of the art and built according to recog-
nised safety regulations. Nevertheless, improper use
can present a hazard to life and limb of the user or third
parties, or result in possible damage to the system and
other property.
Consequently, the unit must only be used properly and
in a technically sound condition.
Any malfunctions which impair safety should be rectified
immediately. Follow the operating instructions!
Proper usage also includes following the operating in-
structions and fulfilling the inspection and maintenance
conditions.
Inappropriate use can be dangerous. Examples of inap-
propriate use include:
– Using in an environment that does not generate an ad-
equate heat load, for example, due to insufficient in-
stalled equipment.
– Using a different condenser unit not supplied by Rittal.
– Use of impermissible tools.
– Improper operation.
– Use of a coolant other than R410A.
– Use of a coolant fill volume other than that specified.
– Installation of the external condenser in an unsuitable
position.
– Operation with less than four installed fans.
– Improper rectification of malfunctions.
– Use of replacement parts which are not authorised by
Rittal GmbH & Co. KG.
– Non-static use, e.g. on moving or vibrating machines.
