Preface
Safety notices
DANGER
 Commissioning is absolutely prohibited until it has been completely ensured that the
machine, in which the components described here are to be installed, is in full
compliance with the provisions of the EC Machinery Directive.
 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 three-phase 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 IEC 61800-5-1, Section 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, DVC-A) that comply with EN 60204-1:2006
can be connected to the connections and terminals between 0 V 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
