Chapter 6 - Electrical installation
6.3.2 Ground cable
It is important that the drive is properly grounded to maintain safety and to
ensure reliable functioning of the equipment.
The ground cable must be securely tied to the ground system of the
installation site and to the ground bus closest to the cable entry of the drive
per national and local code requirements. See section 6.5 Ground cable
and cable shield connections for further information.
Cross-section The cross-section of the ground cable and the ground connection must be
in compliance with national and local electrical codes.
Recommended minimum cross-section of ground cable: 50 mm
2
[1/0 AWG].
6.3.3 Bonding conductor
If the cross-sectional area of the shielding of the cables between the drive
and the motor is less than half the cross-sectional area of that cable, an
extra bonding conductor is required. Running the bonding conductor in
parallel to the power cables is recommended to prevent shield overloading
due to potential differences in the plant. See section 6.5 Ground cable and
cable shield connections for further information.
Cross-section The cross-section and ampacity rating of the conductor and the
connection must be in compliance with national and local electrical codes.
6.3.4 Auxiliary power cables
A three phase 480 V cable is required for the standard auxiliary power
supply (other voltages available by option). A neutral connector is not
required. Type and rating is to be selected according to national and local
code. Auxiliary power is wired into terminal block X01.
See Chapter 2 - Power electronics and cabinet features, for wiring details.
6.3.5 Control cables
Control cables should be provided in accordance with Table 6-1. Either
single or multiple-twisted pair cables may be used.
Control cables should not be laid in parallel to the power cables. Attempt
to keep a minimum distance of 30 cm [12 in] between control and power
cables. Control and power cables should be crossed at an angle of 90°.
Control cables are wired to the IOEC2, fieldbus adapter and terminal block
X10.
See Chapter 3 - Control system, for wiring details.
