Danger and warning information
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.
Only appropriately qualified personnel may commission the SINAMICS units and the
motors.
These personnel must carefully observe the technical customer documentation associated
with this product and be have knowledge of and carefully observe the danger and warning
notices.
Operational electrical equipment and motors have parts and components which are at
hazardous voltage levels. All of the work carried out on the electrical machine or system
must be carried out with it in a no-voltage condition.
When the machine or system is operated, hazardous axis movements can occur.
SINAMICS devices with synchronous motors may only be connected to the power supply
via residual current protective devices if it has been verified (in accordance with EN 50178,
Section 5.2.11.2) that the device is compatible with the residual current protective device.
In combination with the drive system, the motors are generally approved for operation on
TN and TT systems with grounded neutral and on IT systems.
In operation on IT systems, the occurrence of a first fault between an active part and
ground must be signaled by a monitoring device. In accordance with IEC 60364-4-41, it is
recommended that the first fault be eliminated as quickly as is practically possible.
In systems with a grounded external conductor, an isolating transformer with grounded
neutral (secondary side) must be connected between the supply and the drive system to
protect the motor insulation from excessive stress. The majority of TT systems have a
grounded phase conductor, so in this case an isolating transformer must be used.
