Hello, In general, we require that all non-operator replaceable fuse(s) be specified in the service manual. e.g F1 - Type T, 3 A, 250 V.
Ned Devine TUV Product Service [email protected] ------------- Original Text From: Randy Stephens <[email protected]>, on 03/11/1997 10:53 AM: To: <[email protected]> I have a question with regards to IEC 1010-1. Section 5.1.4 states: For any fuses which may be raplaced by an operator there shall be a marking beside the fuseholder specifying the current rating and type ... by the codes of IEC 127. For fuses not replaceable by the operator the same information shall be provided in the documentaion. So, what happens if the fuses which are not replaceable by the operator are not on the AC Mains, but on a secondary circuit? What if these fuses are not IEC 127 type fuses (i.e. micro-fuses, fusible resistors, resistive links, thermal fuses, etc.)? Do we just state exactly what fuse IS currently used in the manual along with a statement that this particular fuse is NOT operator replacable? I am just looking for information where the fuses are on the secondary of an isolation transformer. Any help would be appreciated. Randy Stephens Trek, Inc.
