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.
