Scope of services offered
Unless otherwise stated in the quotation, the scope of services includes all activities,
equipment, materials and expendables required to perform the specified tests. The deadline
and testing period stated, and the quoted cost, can be met only if all the test and inspection
procedures to be performed are clarified in detail in advance. Due to the high capacity utilization
of the associated equipment, it might not be possible to carry out individual inspections and
tests that are requested late if the planned test is already in progress.
If you have received specific requirements from your customer, please send these as soon as
possible – with the necessary key data – to the Nuremberg Vogelweiherstrasse factory.
Sequence of a customer acceptance
A customer acceptance test is generally executed in the sequence:
1. Installation and commissioning of the components before the customer arrives.
2. Kickoff with presentation of the test schedule and discussion of individual steps in the
acceptance test workflow.
3. Execution of the tests according to the test schedule
4. Discussion of the test results
5. Preparation of test documentation for the customer.
The test documentation is created before or after the customer leaves depending on the
scope of testing and the time schedule.

Components provided by customer
Components provided by the customer must be available in plenty of time so that tests can be
carried out on time. The Nuremberg Vogelweiherstrasse factory has no access to components
that are not within the PD LD scope of supply. This also applies to components ordered from
other Siemens' Groups. The technical data for these components is required at the latest eight
weeks before the start of the acceptance test, e.g.:
● Dimensions
● Weights
● Energy Requirement
● Interfaces
Location of the customer acceptance
All customer acceptance tests in the test fields for drives are performed as part of the
manufacturing process.
Note
Limited number of persons in the test field
For safety reasons, the number of persons in the test field is limited. In addition to the regional
sales partner, only two persons from the customer are permitted in the test field at the same
time.
Note
Test without load motors or multipulse infeeds via transformers in the test field
Some tests are simulated or performed in test mode with limited rated data.
Note
Tests with the customer's own cooling units or excitation equipment
If the customer's own cooling units or excitation equipment are to be tested, a system test can
be ordered with option F97.
