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 time 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.
For the 80 kW and 120 kW active line 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.
In a supply system without regenerative feedback capability (e.g. diesel generator), the
regenerative feedback capability of the active line module must be deactivated via a
parameter (see Description of Functions). The braking energy must then be dissipated via
an additional braking module with a braking resistor in the drive line-up.
Caution
The total length of the power cables (motor supply cables and DC link cables) must not
exceed 350 m in sinusoidal current mode.
