Product-specific safety instructions
3.3 Safety instructions for safety-related applications
Loss of the safety function with incorrect wiring
If wiring is incorrect, the motor starter cannot shut down in the event of a fault and the
motor will continue to run. There is a risk of severe injury or death. Material damage is also
possible.
To ensure the safety function, in the case of a single-phase load route the phase and the
neutral conductor through the motor starter. You will find additional information next to the
connection examples in chapter "Single-phase motor (Page 207)". In the case of a
three-phase load, do not connect the neutral conductor to the star point of the load.
NOTICE
Electromagnetic interference
To ensure interference immunity of the motor starter, ground PELV/SELV power supply
units in accordance with regulations. (Please also note the documentation for the
respective power supply unit in this regard.)
