Figure 9-1 Shielding of a Power Module PM340
1. Line supply input
2. Motor cable
3. Rear metal panel
4. Use suitable clamps/clips to reliably connect the shield of the motor and field cable to the
rear metal panel.
5. Shielded cable
Alternatively, the cable shields can be connected to them metal mounting plate using pipe
clamps and serrated rails. The cable length between the shield contact point and the
terminals for cable conductors must be kept as short as possible.
Shield connection plates with pre-prepared clip contacts are available for connecting the
shields for power cables of Power Modules.
All cables inside the cabinet must be connected as closely as possible to parts connected
with cabinet ground, such as a mounting plate or cabinet wall. Ducts made of sheet steel or
routing cables between steel sheets (e.g. between the mounting plate and back wall) should
provide adequate shielding.
Avoid, where possible, routing non-shielded cables, connected to the drive line-up, in the
immediate vicinity of noise sources, e.g. transformers. Signal cables (shielded and
unshielded) connected to the drive line-up must be laid at a great distance from strong
external magnetic sources (e.g. transformers, line reactors). In both cases, a distance of ≥
300 mm is usually sufficient.
