Note
Replacement seal
The seals for the screwed connections can be used only once when the cooling circuit is first
assembled. The seals must be replaced if the circuit is disassembled and assembled again.
The replacement seal is commercially available as flat Viton polymer seal with hardness 75
(+/-5) Shore A (Viton is the commercial name for elastomers with the abbreviations FPM and
FKM). The dimensions are as follows: Outer diameter 26 mm, inner diameter 15 mm,
thickness 1.5 mm.

Electrical connection
Scope of delivery
Six cables to electrically connect the filter reactor with the filter module and two cables to
ground the filter module are included in the scope delivery:
● 6 cables (cross-section 95 mm², reinforced insulation), 820 mm long to connect the filter
module (U1, V1, W1) with the line side of the filter reactor (U1, V1, W1).
The filter module has cable lug connections with diameters for M8 screws
● 2 cables, yellow/green (cross-sections 120 mm²), 1100 mm long for the ground
connection (PE) of the filter module
Sufficient cable is supplied so that the filter reactor and the filter module can be installed as
shown in Section "Notes on installation in a control cabinet (Page 82)".
The ground connection at the filter module must be realized at both PE connections.
Establishing the connections
If the components are arranged as described above, then the cables supplied can be used.
If a different arrangement is used, cables of the same quality must still be used.
