Motor Modules with Cold Plate
7.2 Safety Information
Caution
Motor Modules with a rated current as of 18 A and all Double Motor Modules conduct a high
leakage current via the PE conductor. Because of the high leakage current of the Motor
Modules, a permanent PE connection of the Motor Module or switching cabinet is required.
Measures according to EN 61800-5-1 must be taken (e.g. PE conductor (≥10mm
an additional connection terminal for a PE conductor with the same cross-section as the
original PE conductor).
Caution
The DC link discharge voltage hazard warning must be affixed to the modules in the local
language.
A set of labels in 12 languages is available using order number: 6SL3166-3AB00-0AAx.
Notice
The 80 mm clearances above and below the components must be observed.
Caution
The tightening torque of the DC link busbar screws (1.8 Nm, tolerance: +30%) must be
checked before startup. After transportation, the screws must be tightened.
Warning
Cable shields and unused power cable conductors (e.g. brake conductors) must be
connected to PE potential to prevent capacitive cross-talk charges. Non-observance can
cause lethal shock voltages.
Caution
Only cables from Siemens must be used for DRIVE-CLiQ connections.
