Electrical installation

Connection
When connecting the line filter and line reactor, you must take into account the following
conditions to ensure that they function correctly:
● Control cables must be routed separately from power cables. Power cables are motor
cables or connecting cables from the DC link of the Power Module (terminals DCP/DCN)
to other components (e.g., Braking Module). In particular, you must ensure that control
cables and power cables are not routed in parallel in a joint cable raceway, even if all the
cables are shielded.
