Fig. 9.4 Trick to release the racking in/out push
button by pressing the lever behind the label (2)
NOTE! The rack in / out mechanism works
only when the switch is in the OFF posi-
tion and the other switch is in the I / II
position.
4 Finally, reinstall X22 or X12 in the
PCBA to allow normal operation to
continue.
9.2.3 Release the Racking in/out Push
Button
The in/out mechanism of the rack is elec-
trically and mechanically locked. The rack-
ing in/out push button only works if the
switch is in the OFF position and the
other switch is connected to Source 1 or
Source 2.
If you accidentally press the racking in/
out push button (1), but there is no need
to move the switch to the Test or Isolated
location, there is one special trick: The
racking in/out push button can be re-
leased by pressing the lever behind the la-
bel (2). Otherwise, rotate the switch to
the following possible locations, for ex-
ample from the Connected location to the
Test location.
