Motor Modules Booksize
4.3 Motor Module with external air cooling
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
Module, a permanent PE connection of the Motor Module or control 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 16 languages is available under Order No.: 6SL3166-3AB00-0AAx.
Notice
The 80 mm clearances above and below the components must be observed.
Caution
It is only permissible to establish connections to the DC link using the adapters that Siemens
has recommended (DC link adapter and DC link infeed adapter).
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.
Danger
If a 50 mm wide Motor Module or if a DC link component with the appropriate width
(e.g. Braking Module, Control Supply Module, Voltage Clamping Module) is located at the
lefthand end of the drive line-up, then the DC link bridge including all of the screws must be
removed. It is not permissible to insert the screws without a DC link bridge.
For all other power units and DC link components (e.g. Capacitor Module) that are wider
than 50 mm, it is neither permissible to move the DC link bridge to the left nor remove it.
If this is not carefully observed, this can result in damage and accidents.
