2.4) Installation procedure for AR261, AR265, AR26116, AR26516 rail web
electrical connections
–
Drill rail web or,
if already drilled, use a suitable reamer to clean the hole
(Fig. 1).
–
Check the size of the hole with the
CAL 22.23
“GO/NO GO” gauge (Fig. 2a):
- The hole size is correct
only if the green part enters the hole.
- If the red part enters, the hole is too large
, in this case
it is necessary to drill a new hole.
Using the same gauge, check the rail thickness (Fig. 2b):
- If the yellow band protrudes, use the
AR 265...
series.
- If the yellow band does not protrude, use the
AR 261...
series.
–
Insert the
AR2...-1
copper bush into the rail web hole and position the
AR2...-2
copper
washer on the opposite web side (Fig. 3).
–
Ensure that the ram in the head is fully retracted and then firmly screw and tighten
the
stem of the plunger onto the tool head (Fig. 4).
–
Introduce the stem of the plunger into the
AR2...-2
copper washer and tighten the insert
of the plunger
OG...
onto the stem (Fig. 5) using the recess in the gauge
CAL22.23.
Plungers OG13.2T and OG16.2T are composed of 2
separate items: insert and stem.
To rapidly execute subsequent extrusion operations,
it is sufficient to unscrew the insert, leaving the stem
firmly screwed onto the head.
– Operate the tool (Fig. 6) by pressing the operating button (27) to pull the plunger
OG...
completely
through the bush and the copper washer (Fig. 6); the bush will extrude onto
the side of the hole and into the copper washer that shall be firmly locked (Fig. 7).
To halt the advancement, release the operating button (27): the motor will cut out.
Operate the pressure release lever (28) to retract the ram (16).
2.5) Conductor assembly
– Crimp the two lugs onto the conductors.
– Assemble all pieces as shown in Fig. 8.
– Fit the self-locking nut (Fig. 9) and tighten to the torque ratio indicated.
