PowerFlex 755 IP00, NEMA/UL Open Type Drive
•
All control (I/O) and signal wiring to the drive must use cable with a
braided shield providing 75% or greater coverage, or the cables must be
housed in metal conduit, or equivalent shielding must be provided. When
shielded cable is used, only the drive end of the cable shield should be
terminated with a low-impedance connection to earth. The cable shield
may be terminated either by using a shielded connector in conjunction
with a conduit plate or conduit box, or the shield may be clamped to an
“EMC plate.”
•
Motor cabling must be separated from control and signal wiring wherever
possible.
•
Maximum motor cable length must not exceed the maximum length
indicated in
for compliance with radio frequency emission limits
for the specific standard and installation environment.
•
EMC cores must be applied to input power and motor cabling for some
models of the PowerFlex 750-Series drives as indicated in
.
•
The drive must be powered from an earthed supply system such as a TN or
TT system and the PE-A and PE-B jumpers in the drive must be installed.
Refer to Drive Power Jumper Configuration in the PowerFlex 750-Series
Installation Instructions, publication 750-IN001.
•
IP00 and NEMA/UL Open Type drives must be installed in suitable
supplementary EMC enclosures to achieve compliance with EN 61800-3.
