Electrical connection
General
In the supply line to the Liquid Cooling Package,
please provide the fuse specified on the rating plate
(for single-phase operation e.g. a 20 A pre-fuse), in
order to maintain the necessary protection against
short-circuits even if fully populated with four or six
fans.
Remove the access panel (fig. 38, item 1) by remov-
ing 2 Screws (fig. 38, item 2) with a T25 Screwdriver.

Strain relief
Install a suitable conduit fitting (fig. 38, item 3 – not
supplied) into the ø 23 mm knock-out hole at the top
of the unit.
Feed the power cable through the conduit fitting and
into the existing strain relief (fig. 38, item 4).
Note:
Please keep this electrical documentation
readily available so that it is always on hand
when needed. This is the only documenta-
tion which is authoritative for the unit.
Caution!
Work on electrical systems or equipment
may only be carried out by an electrician
or by trained personnel guided and super-
vised by an electrician. All work must be
carried out in accordance with electrical
engineering regulations.
The unit may only be connected after the
above-named personnel have read this in-
formation.
Use only insulated tools.
The connection regulations of the appro-
priate 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-cir-
cuits. The unit must be individually fused.
The unit has a high discharge current. For
this reason, it is essential to make a
10 mm2 earth connection before connect-
ing to the supply circuit (see section 16.4
"Circuit diagram").
The unit must be connected to the mains
via an isolating device 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.
Note:
The voltage tolerance must not exceed a
maximum of ±10% of the mains voltage
specified on the rating plate.
Note:
Information on the cross-section of the con-
nection cable may be found in section 16.4
"Circuit diagram".
Danger!
Take utmost care not to short-circuit one
of the phases with the zero conductor or
the earth conductor. Otherwise, there is a
risk of damage or injury.
Caution!
Only use copper supply wires.
