Safety information

Dangerous electrical voltage
After disconnecting all the supply voltages, a hazardous voltage will be present in all
components for another 5 minutes. 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.
NOTICE
Maintain ventilation clearances
The ventilation clearances above, below, and in front of the component, which are specified
in the dimension drawings, must be observed.
Potentially fatal touch voltage
Cable shields and power cable conductors which are not used, must be connected to PE
potential in order to discharge charges as a result of capacitive coupling.
Non-observance can cause lethal shock voltages.
Remove linkage levers for frame sizes HX and JX
For Motor 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.
