Engineering Conditions of Acceptability
For use only in or with complete equipment where the acceptability of the combination is
determined by ULLLC. When installed in an end-product, consideration must be given to the
following:
● Reference temperatures on the unit enclosure were measured during heating test. The
max obtained temperature with condition C at Enclosure I was 81.5 °C. See chapter
"Technical specifications (Page 470)" Additional Information for normal load condition
details.
● The unit is completely encapsulated. Potting improve mechanical and thermal properties
of the unit.
● The following Production-Line tests are conducted for this product: Electric Strength,
Earthing Continuity
● The end-product Electric Strength Test is to be based upon a maximum working voltage
of: Primary-Earthed Dead Metal: 300 Vrms, 342 Vpk; Primary-SELV: 300 Vrms, 613 Vpk
● The following secondary output circuits are SELV: 24 Vdc output of the unit.
● The following secondary output circuits are at non-hazardous energy levels: 24 Vdc
output.
● The following secondary output circuits are supplied by a Limited Power Source: 24 Vdc
output.
● The following output terminals were referenced to earth during performance testing:
Terminal P4 (-) during DETERMINATION OF WORKING VOLTAGE - WORKING
VOLTAGE MEASUREMENT TEST.
● The maximum investigated branch circuit rating is: 20 A
● The investigated Pollution Degree is: 2
● Proper bonding to the end-product main protective earthing termination is: Required
● An investigation of the protective bonding terminals has: Been conducted
● The following input terminals/connectors must be connected to the end-product supply
neutral:
Please see chapter "Mounting & connecting (Page 466)".
● The equipment is suitable for direct connection to: AC mains supply
● Output is supplied by circuit that complies with NEC Class 2 requirements (additional
evaluation acc. UL1310 has been conducted during the product investigation).
