Engineering Conditions of Acceptability
For use only in or with complete equipment where the acceptability of the combination is determined by UL
LLC. When installed in an end-product, consideration must be given to the following:
An external VDR and fuse are required in the end application. The VI Brick AC Front End was
evaluated with an external Littelfuse TMOV (VDR).
The VI Brick AC Front End was evaluated with an external fast acting fuse rated 6.3A. Littelfuse
216P series, Bussmann S501 series, and Schurter SA series.
The VI Brick AC Front End provides 1500 Vac / 2121 Vdc of isolation from input/output to EMI
GND/Heatsink (BI), 3000 Vac/ 4242 Vdc from Input to Output (RI), and 1500 Vac / 2121 Vdc of
isolation from Output to Heatsink (SI).
The maximum baseplate / heatsink temperature is 100°C. The heatsink may be grounded or floating
in the end application.
The following secondary output circuits are at hazardous energy levels: All
The power supply terminals and/or connectors are: Not investigated for field wiring
The investigated Pollution Degree is: 2
An investigation of the protective bonding terminals has: Not been conducted
The following end-product enclosures are required: Mechanical, Fire, Electrical
The following secondary output circuits are SELV: all.
