in the axes construction. Refer to the Chapter "Shielding, grounding and equipotential
bonding". Standard MOTION–CONNECT cables, which are available with the standard range
of accessories for the drive system, can be used from this EMC-compliant terminal box
(minimum degree of protection: IP54).
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 DINEN61800-5-1 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 60V can be present at the free cable ends.
• Wait for the discharge time to elapse.
NOTICE
Damage to cables
Cables subject to high acceleration rates can wear more quickly. The cables permanently
connected to the motor cannot be replaced if they are damaged.
• Observe the permissible acceleration rates for the cables.
• Do not use a drag chain for the cables permanently attached to the motor.
