Manual mechanism 2
Operation of manual mechanism 2 (figure 4.1.2.2.1) is purely
manual, with the exception of the motorized stored energy spring
mechanism for the circuit-breaker. The three position disconnec-
tor is mechanically interlocked against the closed circuit-breaker.
Operation of the earthing switch is only possible when the discon-
nector is open, and vice versa.
