Connection
When connecting the du/dt reactor and Voltage Peak Limiter, you must take into account the
following conditions to ensure that it functions correctly:
● Control cables must be routed separately from power cables. Power cables are the motor
cable or the connecting cables from the DC link of the Power Module (terminals
DCP/DCN) to the Voltage Peak Limiter. 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.
● It is recommended to use shielded motor cables. If a shielded motor cable is used, its
shield should be connected through a large surface area with the shield connection plate
in the cabinet and at the motor housing.
● The ground wire for the motor must be fed directly back to the Power Module.
