Electrical installation

Connection

When connecting the output reactor, you must take into account the following conditions to

ensure that it functions correctly:

● With analog control cables, connecting the shield at both ends can result in coupled-in

noise. To prevent this, the shield must only be connected at one end on the Power

Module.

● 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.

● You must use shielded motor cables. The shield for the motor cable must be attached to

the shield plate in the cabinet and motor housing.

● The ground wire for the motor must be fed directly back to the Power Module.
