It must be considered that the spring loaded pin head (60.2) (Figure
4.6) will lie completely on the rear side of the cubicle door when the
hand crank is moved from square spigot of spindle mechanism. This
ensures that the rear part of the pinhead has been shifted onto the
hexagonal cap of the spindle and prevents unintentional wrenching of
the spindle during cubicle service. Wrenching may lead to the circuit-
breaker blocking.
! The withdrawable part must not be stopped in any
intermediate position in the travel range between the
service and test/disconnected position!
