Place the central fan, letting the distance between centers of the impeller
match the middle sign and fix it to the bar by the piercing screws “A” and
“B” as shown in the figures 2 and 4.
The screws must be tightened using an electric screwer. Measure the
distance between centers of the transformer coils and place on the bar
one by one the side fans, letting the impeller middle (figure 1) match the
distance between centers of the coils:
Bar 1200: from 470 to 585 mm
Bar 1800: from 470 to 700 mm
Bar 3600: from 670 to 770 mm
Fix them to the bar by the piercing screws “A” and “B” as shown in the
figure 4.
2) COMPONENTS INCLUDED IN THE KIT.
Bar is supplied with disassembled fans.
A complete ventilation kit is composed of:
• 2 wired ventilation bars
• 6 fans:
TG180 (Bar 1200)
TG360 (Bar 1800)
TG500 (Bar 3600)
• 12 piercing screws to fix the fans on the bars

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.
