Terminal connections X1–X5 without access panel
Then follow the below wiring instructions.
230 V, 1~/208 V, 2~, 3-wire connection
To connect the Liquid Cooling Package to the mains
using a 3-wire, single-phase connection cable, pro-
ceed as follows:
Remove approximately 45 mm from the rubber
sheathing of the flexible cable.
Trim both of the phase conductors (L1 and L2) to a
length of approximately 35 mm. Leave the length of
the PE conductor at approximately 45 mm.
Remove approximately 9 mm from the insulation of
all conductors with a suitable tool.

Dimensions for removing the rubber sheathing and
insulation
Attach wire end ferrules without insulating collars to
the ends of the conductors. To crimp the wire end
ferrules, use a suitable crimping tool with an integral
lock to prevent the tool from opening prematurely.
Insert a suitable screwdriver (blade size 3.5 x
0.5 mm) into an activation opening (fig. 41, item 1)
and open the corresponding terminal connection of
the conductor entry (fig. 41, item 2).

Cooling water connection
The Liquid Cooling Package is connected to the cold
water network via two 1½" threaded pipe connections
(external thread) on the inlet and return, located on the
lower rear of the unit. The connection nozzles are po-
sitioned horizontally to the rear.
Caution!
With a 3-wire, single-phase connection,
the conductor cross-section must be at
least 2.5 mm
