just read schematics
one with jumper is old KRC2 that does not meet modern safety standard because KSP600 safety lacks full redundancy - it only has one contactor K1 (top of KPS600). it does have provision for optional external contactor K1.1 which is added to later versions of KRC2. it is mounted on the left cabinet wall.
mentioned jumper is used to bypass missing feedback from that external contactor by faking missing normally closed contact.
second image show connector with wires going to K1.1 coil and the mentioned feedback. by adding this contactor, safety of older KRC2 can be upgraded.
