Safety Test Procedures

Use the test procedures outlined here only for verifying safe installation or service of the product. The
setups used for these tests and the acceptable ranges of values are derived from local and international
standards but may not be equivalent. These tests are not a substitute for local safety testing where it is
required for an installation or a service event. If using an approved safety tester, perform the tests in
accordance with the information provided by the manufacturer of the tester and in accordance with your
local regulations, for example IEC/EN 60601-1, UL60601-1 (US), IEC/EN 62353, and IEC/EN 60601-1-
1. The safety tester should print results as detailed in this chapter, together with other data.
Please refer to Annex C of IEC/EN 62353 for requirements for the measurement equipment and for
measurement circuits for protective earth resistance and leakage currents.
The following symbols are used in the diagrams illustrating the safety tests:
