Risk of fire due to ground fault/short-circuit
Inadequate installation of the cables between the filter reactor and the filter module can
result in a ground fault/short-circuit and place persons at risk as a result of the associated
smoke and fire.
• Apply the local installation regulations to avoid this fault.
• Protect the cables against mechanical damage.
• Also implement one of the following measures:

Cooling circuit connections

Scope of supply
The unassembled connecting hose is supplied with the loose parts so that it can be adapted
to the local conditions.
Six hose connections (straight and angled) with the associated gaskets are also supplied.
Enough connection hose 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)".
Connection diagram
The cooling circuit connections can be taken from the connection example.
Establishing the connections
If the components and the cooling water feed are arranged as described above, then the
supplied unassembled pressure hose can be used.
If a different arrangement is used, connecting hoses of the same quality must be used:
● Hose diameter 3/4"
● Pressure rating, minimum 12 bar
● Maximum hose length 2 m
● Non-conductive, resistance 1 MΩ/m

WARNING
– Use cables with double insulation.
– Maintain adequate clearance, e.g. by using spacers.
– Lay the cables in separate cable ducts or conduits.
