2.5 Mounting of the auxiliary switch
(fig. 2)
The auxiliary switch is fixed with M8-screws to the base
plate, which in turn is screwed to the locking base plate
(2).
The lever belonging to the operating lever system of the
auxiliary switch is tightened to shaft (1) at the dead-
angle position shown in the figure. The movable pin
of the lever is tigthened at approx. R 31 mm. distance
from the shaft centre. The lever on the auxiliary switch
shaft (11) is loosened and its position is defined by
the curved link that connects the above mentioned
levers. The function of the auxiliary switch can,
when necessary, be adjusted by changing the distance
of the removable bolt from the shaft. Finally the lever
is fixed with a ø 5 mm cotter bolt to the shaft.
When mounted as shown in fig. 2 the operating rod
passes on the right side. If the operaing rod passes
on the left side, the link of the auxiliary switch must be
turned the orher way, then the position of the auxliary
switch and its function fo not change.
When the operation is on the left-hand side the auxi-
liary switch must be tuned 180
o
.
2.4 Mounting (fig. 2)
The main rule. The direction of the closing control
movement of a disconnector is from the bottom upwards
according to the standards.
The manual operating mechanism can be mounted on
the right (C) or left (D) side of the cubicle. The operating
levers are mounted so that the movement direction
of the main rule is obeyed.
The shaft (1) is mounted so that the end of the red
position indicator is max. at same level with the cubicle
front wall. When the disconnector is in the closed
position the position mark is turned upwards to the
I-mark (E). A covered maintenance hole of appr.
ø 100 mm is recommended to be made on the front
panel for removing of the locking magnet.
The link (5 or 6) is cut out to a suitable length. A hole
ø 10.2 mm is frilled to the flat link (6). The excess
length of the tube-link (5) is cut away. Thereafter the end
of the tube-link is fixed with two ø 6 mm cotter bults to
the tube part.
The parts are fixed with M8-bolts and the operation of
the diconnector is tested. The levers 8 and 9 are both
fixed with two 8 mm dia. locking rings.
If the position of the disconnector reguires the use of an
intermediate joint (18), the links and levers are mounted
in the way described previously so that the movement
directions of the main rule are followed.
When mounting the limiting ring (3) the disconnector
must be either in closed or open position. At he same
time it must be checked that the spring loaded bolt in
part 2 is in the middle of the slot of the limiting ring, and
that a gap of 0.5 mm exists between the ring screw and
fixed of the ring are shown in the drawing.
A 1 mm gap is needed between the nut (in part 2) and
the core (13) of the interlocking magnet so that the
anchor would always lock the operating mechanism
(and the disconnecting switch) at its end positions.
The retaining ring (14) is fitted on the shaft according
to the figure so that the radial play is 0.5...1 mm.
2.6 Maintenance
The manual operating mechanism can be serviced e.g.
at the same time as the disconnector. The maintenance
includes lubrication of various bearing and the limiting
ring (3).
