SUBJECT: Changes and additions to UL 5/10 report


The following additions should be made to the UL 5/10 report:

1) Fig. 3 Item 7 (UL Report) Optical Isolator:
       ADD Motorola MCA-231

2) Fig. 4 Item 2 (UL Report) 3" Fan:
       ADD ETRI 99XU-2182

3) Section GENERAL: Internal Wiring
       Change appliance wiring temperature rating FROM 105 C TO 85 C.

We are unsure about the Motorola version of the MCA-231 optical isolator as
to wrether or not it is UL recognized and CSA certified. Its not in our UL
yellow book. Please verify safety agency approval, if any, on this device.
Thank you.
