3.1.3 - Cables and fuses
• It is the responsibilityof the user to connect and provide protection for the POWERDRIVE FX in accordance with the
current legislation and regulations in the country of use. This is particularly important as regards the size of the
cables, the type and rating of fuses, the earth or ground connection, powering down, acknowledging trips, isolation and
protection against overcurrents.
• This table is given for information only, and must under no circumstances be used in place of the current standards.

(1) The value of the rated current and the motor cable cross-sections are given for information only. As a reminder, the motor rated
current permitted by the drive varies according to the switching frequency and the temperature.
(2) The recommended cross-sections have been determined for single-conductor copper cable with a maximum length of 10 m.
For longer cables, take line drops due to the length into account.
Note:
• The cable cross-sections are defined according to the following model:
E.g. for a 100T drive in normal duty, a cable cross-section of (3 x 95 + 50) is given, i.e. 1 bundle consisting of 3 phase conductors
(cross-section 95) and 1 earth conductor (cross-section 50).
• The I
co
output currents are given at an ambient temperature of 40°C. For a temperature above 40°C, derate the current by 1.5%
for every additional degree up to a maximum temperature of 50°C.
