Installing the Slow Operation Device
• Place the support plate (17) of the slow operation device (15) on
the upper right spacer sleeve (18) and prop the device against the
mechanism housing.
• Attach the hook (19) of the slow operation device to the pin (20) of
the support latch (21).
Closing Manually
• Turn the hexagon nut (22) clockwise until the support latch (21) of
the roller follower (23) engages with the opening latch (24) by
audibly snapping into place.
• During the slow closing operation, the opening springs in the pole
columns and the mechanism are charged simultaneously.
Overcharging is prevented by the stop sleeve (25).
• The breaker position indicator is now in the closed position.
