External Shunt Modules 7
Noise Zones for Kinetix 6000 Drives
Observe these guidelines when mounting your external shunt module
outside the enclosure:
•
Mount circuit components and wiring in the very dirty zone or
in an externally shielded enclosure. Run shunt DC-bus and fan
wiring inside metal conduit to minimize the effects of EMI and
RFI.
•
Mount resistors (other than metal-clad) in a shielded and
ventilated enclosure outside the cabinet.
•
Keep unshielded wiring as short as possible. Keep shunt DC-bus
wiring as flat to the cabinet as possible.
•
Route thermal switch and fan wires separate from shunt DC-bus.
