Important information

Installation and/or repairs may only be carried out by trained
and instructed Robert Bosch GmbH customer service staff
or organizations authorized by Robert Bosch GmbH.
Opening or modification of the units by unauthorized
persons will invalidate all warranty entitlements.
Electrical systems and equipment may only be commissioned
in proper condition (see Testing Technology Information
0108_084 for details). This requirement is met if, after
modification or repair (initial test), it is ensured that the
requirements of the electrical engineering regulations are
adhered to. To verify this tests should be performed, the
type and scope of which should be based on the measures
defined in the electrical engineering regulations (e.g.
in Germany BGV A3). In Germany, the type and scope
of the tests are described in VDE 0701/0702 Part 1. The
corresponding national regulations must be adhered to.
