• If required, service factor
• System-dependent conditions, such as ambient temperature, routing type, cable cross-
section as defined by required length of cable, etc.
• Configuration notes
• Requirements according to IEC/EN 60204‑1
• Dimensioning for bundled cable routing, e.g. according to DIN VDE 0298 Part 4 or
IEC 60364-5-52

Hazardous voltages on electrical connections
Dangerous voltages can arise on electric motors. Death, injury or material damage can occur.
Observe the following safety information before connecting up the motor:
• Only qualified personnel should carry out work.
• Carefully follow the 5 safety rules.
• Disconnect the machine from the power supply and take measures to prevent it being
reconnected. This also applies to auxiliary circuits.
• Carefully verify that the machine is in a no-voltage condition.
• Ensure that there is a safe and reliable protective conductor connection before starting any
work.
• The temperature increases if voltage, frequency, waveform and symmetry deviate from their
rated values.
• Carefully comply with the information provided in EN / IEC 60034-1 (VDE 0530-1) regarding
operation at the limits of A and B zones, especially in respect of temperature increase and
deviation of the operating data from the rated data stamped on the rating plate. Do not
exceed these limits. Do not use machines in zone B that are marked for zone A.
• Connect up the machines so that a permanently safe electrical connection is guaranteed (no
protruding wire ends); use the assigned cable-end fittings, e.g. cable lugs, end sleeves.
Connect the connecting cables and arrange the disconnecting link in accordance with the
circuit diagram provided in the terminal box.
• Select the connecting cables in accordance with DIN VDE 0100, taking into account the rated
current and the installation-specific conditions – e.g. ambient temperature, routing method
etc. - according to DIN VDE 0298 and/or EN / IEC 60204‑1.
• Connect motors, as part of the drive system, to TN and TT line supplies with a grounded
neutral point or to IT line supplies.
• Verify that the SINAMICS devices and motors are compatible with the residual current device
according to EN 61800-5-1 before you connect the devices and motors to the line supply
using residual current devices (RCDs).
