The drawing on page 74 of the ATS48 Instruction Bulletin does not work. The shunt trip breaker trips with no fault present.

There is an error in the wiring diagram on figure 33 of page 74. It is necessary to use normally closed contacts from a pilot relay operated by R1A & R1C to operate the trip relay.
See attached ERRATA with correction.
