4.2 Motor Modules with Internal Air Cooling
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.
For the 132 A and 200 A Motor Modules, a ventilation clearance of 50 mm must be observed
in front of the fan.
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.
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.
