Miscellaneous
External AC Fuses ⎯ Recommended Rating
The site's AC supply quality is of great importance. In general, a site with better AC supply
quality (stable nominal voltage) may use smaller breakers.
For Flatpack 1500 sys-
tems use the recom-
mendations in
205VAC table, if you
are sure the available
AC mains voltage will
not drop below
205VAC.
OR
If you are unsure ⎯ or
know that the voltage
may drop below
205VAC ⎯ use the
185VAC table recom-
mendations.
