54 Guidelines for planning the electrical installation
Use symmetrical shielded motor cable (see page 54). Ground motor cable shields 360° at
both ends. Keep the motor cable and its PE pigtail (twisted shield) as short as possible to
reduce high-frequency electromagnetic emissions.
Note: When continuous metal conduit is employed, shielded cable is not required. The
conduit must have bonding at both ends.
A four-conductor system is allowed for input cabling, but ABB recommend shielded
symmetrical cable.
Compared to a four-conductor system, the use of symmetrical shielded cable reduces
electromagnetic emission of the whole drive system as well as the stress on motor
insulation, bearing currents and wear.
The protective conductor must always have an adequate conductivity. The table below
shows the minimum cross-sectional area related to the phase conductor size according to
IEC 61439-1 when the phase conductor and the protective conductor are made of the
same metal.

The table below gives copper and aluminum cable types with concentric copper shield for
the drives with nominal current. For the cable sizes accepted by the drive cabinet lead-
throughs and connection terminals, see page 121.

1. The cable sizing is based on max. 9 cables laid on a cable ladder side by side, three ladder type trays one
on top of the other, ambient temperature 30 °C, PVC insulation, surface temperature 70 °C (EN 60204-1
and IEC 60364-5-52/2001). For other conditions, size the cables according to local safety regulations,
appropriate input voltage and the load current of the drive.
