9.1.2

Safety information

Note
When installing the equipment in cabinets, the ventilation slots must be covered to prevent
drill swarf, wire end ferrules, and the like from falling into the housing.
Safety regulations governing shock protection must be observed. See also EN 60204–1.
Caution
To ensure that the encoder system works properly, you are advised to use the original
Siemens accessories from catalogs D21.1 and D21.2.
Only motors with a safe electrically isolated holding brake may be connected. The brake
conductors must also be safely electrically isolated.
If the motor power cable is connected to intermediate terminals, the power cables and brake
cables must be routed apart (≥ 300 mm).
After an intermediate terminal (e.g. due to a terminal block), it is best to continue routing
using the approved MOTION-CONNECT cable.
Warning
Cable shields and unused conductors of power cables (e.g. brake conductors) must be
connected to PE potential.
Non-observance can cause lethal shock voltages.
