9.2 Safety information
DANGER
To protect against electric shock the components should only be operated in closed
electrical operating areas or in cabinets. Furthermore, an internal protective conductor
connection of the components is absolutely essential.
The components generate high leakage currents in the protective conductor. In order to
ensure protection against electric shocks if the external protective conductor is interrupted,
one of the following measures must be implemented for the external connection:
stationary connection and protective conductor connection by means of ≥ 10 mm
2
Cu or
≥ 16 mm
2
Al
stationary connection and automatic shutdown of the power supply if the protective
conductor is interrupted
DANGER
If the shielding procedures described and the specified cable lengths are not observed, the
machine may not operate properly.
CAUTION
To ensure that the encoder system works properly, you are advised to use the original
Siemens accessories from catalog PM 21.
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 (caused by a terminal block, for example), it is best to
continue routing using the approved MOTION-CONNECT cables.
CAUTION
The conductor pair for the motor holding brake must be themselves shielded (braided
shield). For MOTION-CONNECT cables, this is provided by the inner shield.
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.
