Safety instructions
DANGER
• Commissioning must not start until you have ensured that the machine in which the
components described here are to be installed complies with Directive 98/37/EC.
• SINAMICS devices and AC motors must only be commissioned by suitably qualified
personnel.
• The personnel must take into account the information provided in the technical customer
documentation for the product, and be familiar with and follow the specified danger and
warning notices.
• When electrical equipment and motors are operated, the electrical circuits automatically
conduct a dangerous voltage.
• When the machine or system is operated, hazardous axis movements can occur.
• All of the work carried-out on the electrical machine or system must be carried-out with it
in a no-voltage condition.
• SINAMICS devices with AC motors must only be connected to the power supply via an
AC-DC residual-current-operated device with selective switching once verification has
been provided that the SINAMICS device is compatible with the residual-current-
operated device in accordance with EN 50178, Chapter 5.2.11.2.
WARNING
• The successful and safe operation of this equipment and motors is dependent on
correct transport, proper storage, installation and mounting as well as careful operator
control, service and maintenance.
• For special versions of the drive units and motors, information and data in the Catalogs
and quotations additionally apply.
• In addition to the danger and warning information provided in the technical customer
documentation, the applicable national, local, and plant-specific regulations and
requirements must be taken into account.
• Only protective extra-low voltages (PELV) that comply with EN60204-1 may be
connected to all connections and terminals between 0 and 48 V.
CAUTION
• The motors can have surface temperatures of over +80 °C.
• This is the reason that temperature-sensitive components, e.g. cables or electronic
components may neither be in contact nor be attached to the motor.
• When attaching the connecting cables, you must ensure that:
– they are not damaged
– they are not under tension
– they cannot come into contact with any rotating parts
