I5300 User Manual
The installation precautions are as follows:
• Symmetrical shielded cable is recommended. The four-conductor shielded cable can
also be used as an input cable.
• The motor cable and PE shielded conducting wire (twisted shielded) should be as
short as possible to reduce electromagnetic radiation and external stray current and
capacitive current of the cable. If the motor cable is over 100 meters long, an output
filter or reactor is required.
• It is recommended that all control cables be shielded.
• It is recommended that a shielded cable be used as the output power cable of the AC
drive; the cable shield must be well grounded. For devices suffering from interference,
shielded twisted pair (STP) cable is recommended as the lead wire and the cable
shield must be well grounded.
7.4.2 Cabling Requirements
1) The motor cables must be laid far away from other cables. The motor cables of several
AC drives can be laid side by side.
2) It is recommended that the motor cables, power input cables and control cables be laid
in different ducts. To avoid electromagnetic interference caused by rapid change of the
output voltage of the AC drive, the motor cables and other cables must not be laid side
by side for a long distance.
3) If the control cable must run across the power cable, make sure they are arranged at
an angle of close to 90°. Other cables must not run across the AC drive.
4) The power input and output cables of the AC drive and weak-current signal cables
(such as control cable) should be laid vertically (if possible) rather than in parallel.
5) The cable ducts must be in good connection and well grounded. Aluminium ducts can
be used to improve electric potential.
6) The filter, AC drive and motor should be connected to the system (machinery or
appliance) properly, with spraying protection at the installation part and conductive
metal in full contact.
