Safety information

Warning
After disconnecting all the supply voltages, a hazardous voltage will be present in all
components for another 5 minutes. The protective cover must not be opened until this time
has elapsed.
The DC link protective cover must be released using an insulated screwdriver.
Caution
The DC link discharge voltage hazard warning must be affixed to the modules in the local
language.
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
The tightening torque of the DC link busbar screws (1.8 Nm) must be checked before
startup.
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.
