Question:
Does the wording:
"Fuse-links, fusing resistors and thermal releases affecting the safety of the apparatus
+ F3 U: W+ m, p  W+ O0 ashall not operate during the test"
mean that:
a) if a fuse-link, fusing resistor, or thermal release operates during the test, it shall be
defeated and the test continued.
