General scope of services

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.
