Safety information

Dangerous electrical voltage
A hazardous voltage will be present in the component for a further 5 minutes after all
voltage supplies have been disconnected. Work cannot be carried out until this time has
elapsed.
Before starting work, you should also measure the voltage after the 5 minutes have
elapsed. The voltage can be measured on DC-link terminals DCP and DCN.
Danger notice in the local language
The DC-link discharge time hazard warning must be affixed to the component in the
relevant local language.
Note
Maintain ventilation clearances
The ventilation clearances above, below, and in front of the component, which are specified
in the dimension drawings, must be observed.
NOTICE
Use on a line supply where energy recovery is not possible
In a supply system without regenerative capability (e.g. diesel generator), the regenerative
feedback capability of the Smart Line Module must be deactivated in the relevant
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.
Remove linkage levers for frame sizes HX and JX
For Line Modules of frame sizes HX and JX, the linkage levers marked in red must be
removed once the devices have been installed.
Non-observance can cause damage to the device through undershooting the necessary
voltage clearances.
