Place the cooling fan unit on the I-beams of the transformer track in or-
der to direct the air flow inside the coil air ducts (
figure 5
).
Drill two holes of at least 11 mm where the bar rests on the track and fix it
with bolts of minimum 10MA, interposing a spring washer as shown in
figure 6
.
To optimize the flow direction, it is possible to adjust the flapper angle,
paying attention to respect a minimum distance flapper-coil of 8 cm.
By tightening the flapper hinge screws, it is possible to clamp the posi-
tion.
4) MOUNTING OF THE BAR ON THE TRANSFORMER
Connect the input power supply of each fan with the relevant cable as
shown in figures
8,9,10 and 11
.
Each cooling fan unit is equipped with a connector block containing a ter-
minal for connection to the mains, as shown in
figure 7
.
N.B.: in order to assure a suitable fan protection, we suggest to
feed them with TECSYSTEM monitoring unit model VRT200.
