3.4 - Description of cables and protective devices
3.4.1 - General characteristics
• It is the responsibility of the user to connect the DIGIDRIVE and fit protective
devices in accordance with the legislation and regulations in force in the country
of use. This is particularly important as regards the size of the cables, the type and
size of fuses, the earth or ground connection, powering down, acknowledging faults,
insulation and protection against overcurrents.
• The following table is given for information only, and must under no
circumstances be used in place of the current standards.
* The recommended cross-sections are given for a single-wire cable whose maximum length
is 10 metres. Above this, the line drops due to the length must be taken into account.
Note:
• The temperature withstand of the cables used for the control and power cables must be at
least 105°C.
• The protective fuses must conform to EN 60269 parts 1 and 2.
