Commissioning - Siemens SINAMICS DCM Operating Instructions Manual

Commissioning

This unit is subject to hazardous voltage levels and contains dangerous rotating machine
parts (fans). Failure to comply with these Operating Instructions can lead to death, serious
physical injury, and material damage.
Dangerous voltage levels may be present at the signaling relays at the customer's site.
The units may be connected to a line supply with residual current operated circuit breaker if
a universal current sensitive device is being used, which in the case of a ground fault, can
also detect a DC component in the fault current. We recommend a residual current
operated circuit breaker with an operating current ≥300 mA, which means that it is not
suitable to protect personnel. If you have additional questions, please contact Technical
Support.
Only qualified personnel who are familiar with all the safety instructions in this description,
as well as the installation, operating, and maintenance instructions, should carry out work
on this unit.
Perfect, safe, and reliable operation of this unit is conditional upon it having been
transported, stored, mounted, and installed correctly, as well as carefully operated and
serviced.
The unit is subject to dangerous voltage levels even when the converter unit's line
contactor is open. The control module (Power Interface) contains several circuits that are
subject to dangerous voltage levels. Before commencing maintenance or servicing work,
disconnect all current sources of the converter infeed and disable them.
To operate the SINAMICS DC MASTER, both front cover fixing screws must be tight.
These instructions are not exhaustive and as such cannot outline all the measures required
in order to operate the unit safely. Where necessary, additional information or instructions
may be required for special applications. If you encounter specific problems which have not
been handled in enough detail for the purposes of the buyer, please contact your local
Siemens office.
The use of non-approved parts for carrying out repair work on the unit or handling of the
unit by inadequately qualified personnel will result in dangerous conditions with the risk of
death, serious physical injury, or extensive damage to equipment. All safety measures
listed in these Operating Instructions, as well as all warning signs attached to the unit, must
be followed.
Observe all the warning information outlined in Chapter 1 of these Operating Instructions.
