Information on the disconnector unit
Disconnector units for Active Line Modules, Basic Line Modules, and Smart Line Modules
A disconnector unit is required for disconnecting the drive line-up from the supply system
correctly. The disconnector unit of the machine's electrical equipment can be used for this
purpose. The disconnector unit must be selected in compliance with the requirements of the
internationally binding standard relating to the electrical equipment of machines IEC 60204-
1, Section 5.3. The relevant technical data and any other loads connected to the electrical
equipment must be taken into account when making your selection.
Damage to the drive electronics when switching the line disconnection equipment under
load
When switching the line disconnection equipment (type according to the recommended
selection) under load, then the contacts will be subject to premature wear. This can cause
the line disconnection equipment to malfunction, with subsequent damage to the drive
electronics.
• Use a leading opening auxiliary contact or use a Voltage Sensing Module (VSM10).
• If this is not possible, then avoid switching the line disconnection equipment under load.
The accessories required for the disconnector unit must be selected from the manufacturer
catalogs. Refer also to catalogs PM21 and NC61.
