dents:
1. Switch off!
Switch off the LCP DX at the master switch.
2. Prevent reactivation!
3. Ensure that all poles are de-energised!
4. Earth and short-circuit!
5. Cover or shield adjacent, live parts

);
3. Instructions for switching off the cooling system in
an emergency (see section 7.2.3 "Switching off in an
emergency");
4. The maximum permissible pressures (see
section 11 "Technical specifications").

System log
Under DIN EN 378, the operator is required to keep a
system log and ensure that it is regularly updated. The
system log should contain the following information:
1. Details of all repair work
2. Quantity and type (new, reused or recycled) of refrig-
erant added, quantity of refrigerant removed
3. Outcome of any analysis of reused refrigerant, if

Caution! Risk of malfunction or damage!
Proper and flawless unit operation can
only be ensured when it is operated un-
der the intended ambient conditions. As
far as possible, observe the ambient
conditions for which the unit was de-
signed, e.g. temperature, humidity, air
purity.
Caution! Risk of malfunction or damage!
All media required for the control sys-
tem, such as the correct fill volume of
coolant, must be available throughout
the entire operating period of the device.
Caution! Risk of malfunction or damage!
Installation, and in particular the coolant
line pipework between the external con-
denser and the LCP DX, must only be
carried out by trained, qualified and ac-
credited cooling system specialists.
Caution! Risk of malfunction or damage!
In order to prevent EMC-related mal-
functions during operation, and to allow
access for servicing purposes, cross-
wiring through the LCP DX to the bayed
racks is prohibited.
Note:
Rittal offers leak testing of the device as a
service.
