Siemens SIMOTICS L-1FN3 User Manual

WARNING
Electric shock caused by high leakage currents
When touching conductive parts of the machine, high leakage currents can result in an electric
shock.
• For high leakage currents, observe the increased requirements placed on the protective
conductor. The requirements are laid down in standards DINEN61800-5-1 and DIN EN
60204-1.
• For high leakage currents, attach warning symbols to Power Drive System .
WARNING
Risk of electric shock as a result of residual voltages
There is a risk of electric shock if hazardous residual voltages are present at the motor
connections. Even after switching o󹪜 the power supply, active motor parts can have a charge
exceeding 60 μC. In addition, even after withdrawing the connector 1 s after switching o󹪜 the
voltage, more than 60V can be present at the free cable ends.
• Wait for the discharge time to elapse.
6.2 Important information about the electrical connection
Naturally cooled 1FN3 linear motors have 3 permanently connected single-core cables to
connect the power and 1protective conductor connection 0.5m long.
The motor has 2 temperature signal conductors with a minimum length of 0.25 m to connect
the temperature sensors to the drive. The two signal cables are combined and encased with a
protective 󹪞exible tube and a shrink-on sleeve to form one signal cable.
All core ends are open.
