OPENING THE CABINET (Fig. B)
To open the SNAP4 control unit cabinet, turn the lock 1 (Fig. B) clockwise and lift the lid, turning it as shown in Fig. B
point 2.
Once the lid has been removed, the door can be lifted off.
PRELIMINARY CHECKS AND INSTALLATION ON THE GROUND
Before proceeding with installation as such, check that the point where the barrier is to be installed is solid and suitable,
allowing the barrier to operate correctly.
If the SNAP4 is installed on a solid concrete base, it can be fixed directly to the ground with 4 expansion plugs D.12 (fig. E1), or
it can be secured with the aid of the counterplate (FIXSNAP4), complete with anchor bolts (fig. E2); in this case, proceed as
follows:
1. Dig out the foundation, bearing in mind the size of the foundation counterplate.
2. Place raceways in the hole for the power supply and connection wires
3. Fit the counterplate and anchor bolt as shown in fig. E2.
4. Sink the raceways and foundation plate in concrete and check that they are horizontal.
5. Unscrew the nuts of the 4 anchor bolts once the concrete has set..
6. Place the SNAP4 on the counterplate, fixing it with the 4 washers and 4 nuts provided.
RELEASING THE BARRIER
To release the barrier, proceed as shown in figure D:
1. Insert the release key and leave it in place.
2. Turn the hexagonal key 270 degrees anti-clockwise until it reaches the mechanical limit stop.
The bar has now been released from the gear motor.
To re-engage the bar:
1. Insert the release key (1) and leave it in place.
2. Turn the hexagonal key 270 degrees clockwise.
INSTALLING THE BARRIER
N.B.: all the information which follows refers to a right-handed barrier installation as shown in figure C.
The electrical connection should be made with a 3x1.5 power supply cable.
1. Lay an underground duct to take the electrical power supply and safety cables.
2. Install the barrier on the ground as already described.
3. Release the rod, bringing the barrier to the rod lowered position. The side of the swing arm on which the spring is
fixed should be upward. See fig. G2 (RIGHT-HAND barrier).
4. Fix the bar support anchor plate with the four screws, with the long side horizontal (Fig. F1). The screws must be
tightened to a torque of more than 70 Nm.
5. Mount the bar support, fitting the four screws. The side of the support with the stop screw must be the side opposite
the passage area (see arrow in fig. F2).
6. Insert the bar in the support (side with brace) until it reaches the stop (the stop screw).
7. Fully tighten the bar support screws and fit the cap (Fig.F3).
8. Move the bar to 90 degrees and connect the spring.
9. Then pull the spring so that the bar (released) remains in equilibrium at 45 degrees. Further adjustments can be
made by shifting the fulcrum of the spring on the swing arm (fig. G): move the fulcrum nearer to reduce the overall
moment or move it away to increase.
10. Check that the bar remains virtually still at 20 and 70 degrees.
11. Lock the gear motor.
12. Make the necessary electrical connections by connecting the power supply line to the terminals in the box inside the
cabinet.
13. Proceed with the installation and configuration of the control unit (see following points).
