The cable sizing is based on NEC Table 310-16 for copper wires, 75 °C (167 °F) wire insulation at 40 °C
(104 °F) ambient temperature. Not more than three current-carrying conductors in raceway or cable or earth
(directly buried). For other conditions, dimension the cables according to local safety regulations, appropriate
input voltage and the load current of the drive.
1)
The table gives DC cable types when the cables are outside the cabinet. For DC cables inside the cabinet,
select a cable capable of carrying 2/3 of the continuous output current of one drive module.
*)
Connection (1× xxx): One phase conductor of the three-phase cable between the DC+ terminals of the drive
modules and another phase conductor of the three-phase cable between the DC- terminals of the drive
modules. The third phase conductor unconnected.
**)
Connection (2 × (3 × xxx)): two phase conductors of one three-phase cable between the DC+ terminals of
the drive modules and two phase conductors of the second three-phase cable between the DC- terminals
of the drive modules. The third phase conductors unconnected.
Terminal and entry data for the power cables
The maximum accepted cable size is 4×(3×240) mm
2
or 4×(3×500 AWG). Screw size for
connecting busbars to the drive module input and output busbars: M12, tightening torque
50…75 N·m.
￭ Units without full-size output cable connection terminals and with a
common mode filter (+E208)
It is possible to use the maximum cable size (4×[3×240] mm
2
or 4 ×[(3×500 AWG]) only
with special cable lugs and additional insulation. For more information, contact your local
ABB representative.
