5.1 General
5.1.1 Installation site requirements
In order to ensure problem-free operation of the
LCP DX, the following conditions for the installation site
should be observed:
Positioning of the LCP DX in the server room rela-
tive to the external condenser
The interior device (LCP DX) and the external condenser
must be connected with a suitable copper pipe connec-
tion in accordance with DIN EN 378-2. The entire sys-
tem must then be filled with coolant (see section 6.2
"Notes on pipework").

Tab. 3: Supply connections required at the installation site
Note:
A voltage of at least 380 V is required to start
the device.
If the mains voltage briefly drops 10% below
380 V with the system operational, it will not
malfunction.
Note:
Please also observe the instructions and data
relating to the coolant connection as outlined
in section 6 "Installation".
