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 59)".
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.
Risk of fire and damage to equipment due to short-circuit / ground fault
The cables to the filter module must be routed so that a ground fault or short-circuit can be
ruled out. A ground fault can result in fire with associated smoke.
• Protect the cables from mechanical damage
• Comply with local installation regulations that enable this fault to be ruled out.
In addition, apply one of the following measures:
• Use cables with double insulation.
• Maintain adequate clearance, e.g. using spacers.
• Route the cables in separate cable ducts or pipes.
