HARDWARE
CABLES
This chapter describes solely the cables to be used in the installation of
the QC-PDS system and the characteristics of the connectors of those
cables. Its mechanical characteristics are also detailed.
The Installation chapter in this manual describes the cabling of the QC-
PDS system for the power lines, feedback, optic fiber of the SERCOS-II
ring o SERCOS-III Ethernet line topology cable, communications and
others are described in the following chapter on installation manual.
The attached T. H7/1 table determines the minimum cable section required
for the maximum allowable current in a continuous duty circulating
through copper conductors that are installed inside PVC conduits or
channels · least favorable installation method
·.
MANDATORY. The length of any cable used in the installation of the QC-
PDS system must be shorter than 30 m, except for the power (motor),
feedback (encoder) and fiber optic (SERCOS-II interface) cables or the
Ethernet (SERCOS-III interface) cables, which may exceed this length.
MANDATORY. The dielectric insulation of the cable must be enough to
withstand the test voltage at a minimum of 2 000 V AC for 5 minutes for
cables supporting voltages over 50 V AC (alternating current) or 120 V
DC (direct current). Refer to the recommendations of the cable
manufacturer before doing the installation.
