Siemens 3NA38 series fuses and 3RV series motor starter protectors of a lower current rating than
shown may also be used. The converter must be mounted in a suitable enclosure (e.g. metal
equipment cabinet).
If a motor starter protector is used, the enclosure interior volume should not be less than that shown
in the table above.
Branch circuit protection according to UL standards
Use in North America requires protection devices that meet UL standards as detailed in the
following tables. The converter must be mounted in a UL approved enclosure not less than the
minimum enclosure volume unless the branch circuit protection is a class AJT fuse by Mersen
(Ferraz Shawmut).

Product information 07/2015
Modified behavior when commissioning the drive
With firmware V4.7 SP3, the commissioning Wizard has been revised and standardized for the
following inverters:
•SINAMICS G120 with PM240, PM240-2 or PM330 Power Module
•SINAMICS G120C
The SINAMICS application classes Standard Drive Control, Dynamic Drive Control and Expert
have been newly developed. The commissioning Wizard sets the application class depending on
the particular inverter:
•Standard Drive Control for SINAMICS G120C and SINAMICS G120 with Power Module
PM240, PM240-2 up to frame size FSD
•Dynamic Drive Control for SINAMICS G120 with PM240, PM240-2 Power Modules from
frame size FSD and with PM330 Power Modules
•Expert for SINAMICS G120 with PM230, PM250 and PM260 Power Modules
Motor data identification (MotID) is permanently set for Standard Drive Control. After the
commissioning Wizard has been exited, the inverter responds to the first ON command as follows:
1. The inverter carries out a MotID with the motor at a standstill. The duration of the MotID,
when compared to firmware V4.7, was shortened to approx. ⅓.
2. The inverter accelerates the motor to the specified setpoint. The second ON command
after the MotID is not necessary for Standard Drive Control.
For Dynamic Drive Control, a MotID is also set as default with the motor at a standstill. The default
setting can be changed:
•In addition, you can also select the MotID with rotating measurement. The inverter
optimizes the closed-loop speed control based on the results of the rotating measurement.
•You can select as to whether, after the MotID, the motor immediately accelerates to the
specified setpoint, or a second ON command is required.
To a large extent, Expert corresponds to the commissioning Wizard for firmware < V4.7 SP3.
A MotID is not set as default. You can select the following:
•No MotID, MotID with measurement with the motor at a standstill or MotID with rotating
measurement
•After the MotID, the motor immediately accelerates to the specified setpoint, or only after a
second ON command.
The following commissioning tools support the new commissioning wizard:
•STARTER from 4.4 SP1 or higher
•Startdrive from V13 SP1 and higher with Hardware Support Package V4.7 SP3
•IOP from V1.6 and higher
•BOP-2

Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.
