er, so that any condensate can be discharged from the
device.
6.4 Electrical connection
6.4.1 General
The LCP DX and the external condenser are supplied
with voltage independently of one another.
6.4.2 Connecting the LCP DX
Power is supplied to the LCP DX via a 5-wire connection
cable (380…415 V, 3~, N, PE). The cable may either be
inserted into the device from above via a brush strip, or
alternatively, if the device is operated in a room with a
raised floor, from below.

1 Cable gland, power supply
2 Cable gland, collective fault signal
3 Network connection (optional)
Inside the device, the cable is routed into the electronics
box via the large cable gland in the centre (fig. 26,
item 1). It is connected to the appropriately labelled ter-
minals (PE, L1, L2, L3, N) in the electronics box.
Note:
In order to ensure safe condensate dis-
charge, the following points should be ob-
served:
– Lay the drainage hose so that it always
runs downhill and without any kinks.
– Do not constrict the hose cross section.
Note:
Please keep the wiring plan readily available
so that it is always on hand when needed.
This is the only authoritative documentation
for this unit.
Caution!
Work on electrical systems or equip-
ment may only be carried out by an elec-
trician or by trained personnel under the
guidance and supervision of an electri-
cian. All work must be carried out in ac-
cordance with electrical engineering
regulations.
Contact with live electrical parts may be
lethal.
The unit may only be connected after the
personnel mentioned above have read
this information!
Use only insulated tools.
The connection regulations of the ap-
propriate electrical power company are
to be followed.
The voltage values shown in the wiring
plan or on the rating plate must match
the mains voltage.
The pre-fuse specified in the wiring
plan / rating plate should be provided to
protect the cable and equipment from
short-circuits. The unit must be individu-
ally fused.
Caution!
The unit has a high discharge current.
Before connecting to the supply circuit,
therefore, it is essential to make a 6 mm²
earth connection (see section 16.4 "Cir-
cuit diagram").
The unit must be connected to the mains
using an all-pole red/yellow isolating de-
vice as described in DIN EN 60204-1,
section 5.3, which ensures at least 3 mm
contact opening when switched off.
No additional control equipment may be
connected upstream of the device at the
supply end.
