First Level AC Power Fault Criteria

Table 4.6 presents test conditions for the First Level AC Power Fault Test. The EUT is

required to pass operationally.

Notes:

1. For EUT containing secondary voltage limiting and current limiting protectors, tests are to be performed at the indicated voltage(s)

and repeated at a reduced voltage and current just below the operating threshold of the secondary protectors.

2. Test 5 simulates a high impedance induction fault. For specific information, please contact Teccor Electronics.

3. Test conditions 6 through 9 are objective, not mandatory, requirements.

4. Sufficient time may be allowed between applications to preclude thermal accumulation.

Second Level AC Power Fault Criteria

Test conditions for the Second Level AC Power Fault Test are dependent on whether the

EUT is intended for customer premises equipment or non-customer premises equipment. In

both instances, although the EUT is not required to pass operationally, it may not become a

fire, fragmentation, or electrical safety hazard.

Second Level AC Power Fault Criteria for Non-customer Premises

Equipment

Table 4.7 presents test conditions for non-customer premises equipment. (Note that test

conditions 1, 3, and 4 may be omitted if the EUT has previously met UL 60950.) See

Figure 4.1 for test connection appearances.
