Commissioning
Warning
Working on the equipment by unqualified personnel or failure to comply with warnings can
result in severe personal injury or serious damage to material. Only suitably qualified
personnel trained in the setup, installation, commissioning and operation of the product
should carry out work on the equipment.
Caution
Cable connection
The control cables must be laid separately from the power cables. Carry out the
connections as shown in the installation section in this manual, to prevent inductive and
capacitive interference from affecting the correct function of the system.
During Operation
Warning
The SINAMICS G120 inverters operate at high voltages.
When operating electrical devices, it is impossible to avoid applying hazardous voltages to
certain parts of the equipment.
Emergency Stop facilities according to EN 60204, IEC 204 (VDE 0113) must remain
operative in all operating modes of the control equipment. Any disengagement of the
Emergency Stop facility must not lead to an uncontrolled or an undefined restart of the
equipment.
Certain parameter settings may cause the SINAMICS G120 inverter to restart
automatically after an input power failure, for example, the automatic restart function.
Wherever faults occurring in the control equipment can lead to substantial material
damage or even grievous bodily injury (that is, potentially dangerous faults), additional
external precautions must be taken or facilities provided to ensure or enforce safe
operation, even when a fault occurs (e.g. independent limit switches, mechanical
interlocks, etc.).
Motor parameters must be accurately configured for motor overload protection to operate
correctly.
This equipment is capable of providing internal motor overload protection according to
UL508C.
Only Control Units with fail-safe functions can be used as an "Emergency Stop
Mechanism" (see EN 60204, section 9.2.5.4).
