1_ Fix the rear bracket in the position determined before. In the
event of iron pillar carefully weld directly the bracket or use 4
suitable screws (pic. 6). In the event of brick pillar (pic. 7), use 4
suitable bolts (after you have assembled the bracket, pic. 7A).
During the fastening operations, check if the bracket is
perfectly horizontal by means of a level.
WARNING - In case of large gate leaves and/or closed
design leaves, other than the installation of an electro
lock it is suggested to strengthen the fastening of the
back bracket (weld the steel parts instead of using
screws to assemble the bracket, use steel anchors
instead of the dowels, weld the bracket onto the pil-
lar, etc.).
2_ After removing the terminal board cover, anchor the actuator to
the rear bracket using the screw and nut supplied (see 1, pic. 8);
ATTENTION: carefully verify that, when gate is closed,
the actuator's rear do not touch the bracket (see pic.
8). If so adjust the setting accordingly.
3_ Make sure that the lead screw carrier block (1, pic. 9A) is in the
position as shown in pic.9A (at a distance of approx. 10 mm
from the cap). If this is not the case, in order to adjust the posi-
tion of the lead screw carrier block, the gate operator should be
momentarily powered.
ATTENTION: The operator can be moved by hand only if it
is installed on the gate and in released position (see MAN-
UAL RELEASE).
4_ check the distance "C" (pic. 4);
5_ assemble the leaf bracket as shown in pic.10;
6_ rest the bracket that has just been fixed, onto the leaf of the
completely closed gate and mark height of welding or the fixing
points (make sure it is level, see pic. 11).
Before going on to the next phase please carry out the following
test:
7_ release the actuator (see MANUAL RELEASE) and manually
check if the gate can completely open without hindrances and
stop at the mechanical stoppers (or floor-mounted mechanical
stoppers) as well as if the leaf moves regularly without any fric-
tion.
8_ carry out the necessary corrective measures and repeat from
point 7. Manually open the gate to the maximum required an-
gle;
9_ using the same method as in point 3, position the lead screw
carrier block towards the motor until the leaf bracket overleaps
the position previously marked on the leaf. If it does, the instal-
lation nas been prperly done.
This procedure can be used to establish where the leaf bracket
should be welded for each opening angle (X°), provided it is pos-
sible (parameters A and B as well as the stroke must allow it).
10_ weld the leaf bracket in the position indicated (pic.12A), ac-
cording to pic. 13 and ensuring the planarity of the assembly.
Alternatively, you can use the multipoint bracket, to be as-
sembled as shown in pic. 12B.
Note: if the gate structure does not allow a fix bracket
fastening it is necessary to create a sturdy support-
ing base in the gate structure.
11_ Move the open mechanical stopper (1, pic. 9B - optional) to
enable opening of the leaf to the required angle. To access
the locking screws of the mechanical stopper (2, pic.9B), the
operator needs to be moved manually (see MANUAL RE-
LEASE). Check the precision of the setting by performing a
manual cycle with the actuator released, making corrections
if necessary. You can also install the closing mechanical stop-
per (optional).
Note: next settings to increase the stroke of the op-
erator WILL NOT be possible, as the fastening dow-
els of the mechanical stopper (2 pic. 9B) incise the
endless screw, compromising the correct sliding of
the fork.
12_ ARM3000IFC: nominal stroke is 450 mm; to adjust stroke,
loosen the locking nuts (1, pict. 9C) and set the limit switch
to the required position. Max. adjustment is 50 mm. One the
adjustment is completed, tighten the locking nuts again (1
pict. 9C).
Note: for complete safety, both OPEN and CLOSE
floor-mounted mechanical stoppers must be installed
(8, pic.3).

OPTIONAL ACCESSORIES
P-650ARMKITFCR - Set of mechanical stoppers, containing:
nr. 2 mechanical stoppers;
nr. 4 M5x20 screws.
WIRING THE ACTUATOR
A terminal board is located in the rear part of the operator for the
connection of the motor, of any limit switch and for the grounding
of the operator (pic.14-15).
Connect the motor and the grounding as per pic.14-15 and the
table.

Use only control units with electric clutch.
The distance between the control unit and the motor must not ex-
ceed 10 – 12 m.
TAU srl recommends its composite cable, Code M-03000010CO;
Place the control unit (external versions) in the im-
mediate vicinity of the motors.
Be careful not to run cables for auxiliary devices in-
side raceways housing other cables supplying power
to large loads or lights with electronic starters.
In the event control pushbuttons or indicator lights
are installed inside homes or offices several metres
away from the actual control unit, it is advisable to
decouple the signal by means of a relay in order to
avoid induced interference.
START-UP
ATTENTION: Cut power before any job on the opera-
tor or the controller.
Carefully observe points 10, 11, 12, 13 and 14 of the SAFETY
GENERAL RULES.
With reference to the indications in pic. 3 and in the table (see
INSTALLATION), set the ducts and carry out the electrical connec-
tions of the control board and of the chosen accessories.
Choose short routes for cables and keep power cables separate
from control cables.
1) Power the system and check the status of the LEDs according
to the control unit instructions.
2) Program the control board according to the needs by following
the given instructions.
TESTING THE AUTOMATED SYSTEM
• Carefully check operating efficiency of the gate operator and of
all accessories connected to it, paying special attention to the
safety devices.
