Information about line isolating devices

Only valid for Active Line Modules, Basic Line Modules and Smart Line Modules
The line disconnecting device for the electrical equipment may be used for correct isolation
of the drive line-up from the power supply. This line disconnecting device must be designed
for the electrical equipment of machines in accordance with the requirements of EN 60204-1,
Section 5.3. The relevant technical specifications must be taken into consideration for the
purpose of selecting the device. Other consumers of the electrical equipment must also be
taken into consideration when the device is selected.
NOTICE
If a drive line-up is switched off by means of the line disconnecting device, on power units
with regenerative feedback capability, the voltage at terminals 3 (EP +24 V) and 4 (EP M)
must be interrupted beforehand. This can be carried out using a leading breaking auxiliary
contact (≥ 10 ms), for example.
This protects external loads located parallel to the drive on the same switching component.
The accessories required for the line disconnecting device must be selected from the
manufacturer catalogs. See also catalog D21.1.
