3 INSTALLATION
3.1 FOUNDATION DETAILS
Important note- the following details are typical only. Please refer to site-specic drawings,
which were issued with your order.
Barrier xings M16 x 135
Hilti Type HAS bolts
End support xings
M10x120 Hilti type HAS
bolt.
Ensure concrete
foundations are suitable
for secure xing of these
bolts
Bases must be perfectly
level in themselves, to
prevent the need for
excessive shimming of
equipment.
End support post if
supplied is telescopic.

3.2 BARRIER INSTALLATION
• Before installation commences thoroughly check all base sizes and positions in accordance
with the issued drawings.
• Check the quantity, sizes and positions of all installed mains, control and loop cables
within the ducts.
• With beam removed, position barrier as shown on the drawings and check the supplied
beam length is equal or more than, that which is required.
• For guidance only and if an end support post is being used: -
• If Trief kerbs are installed, the beam should be at least 1124mm longer than the kerb-to-
kerb width.
• If standard kerbs are installed, the beam should be at least 604mm longer than the kerb-
to-kerb width.
• If there are no kerbs the beam length should be at least 364mm longer than the
foundation-to-foundation width.
• Fix the barrier in position using 1 M10 Hilti type bolt in the central xing position. Ensuring
that the cables are pulled through the rectangular 100 x 250 cut out in the barrier base
plate.
• Connect the mains supply into the isolator.
• Connect the control and loop cables (if installed.)
• Check the barrier raises and lowers correctly.
• Lower the barrier to horizontal. The mains must now be isolated using the isolator
switch within the barrier cabinet.
• Attach the barrier beam.
• Check the alignment of the beam across the entrance, ensuring that it lies central within
the end support post (if supplied).
• Fit the remaining 5 x M16 xing down bolts, ensuring that the barrier base is shimmed
level before the bolts are fully tightened.
• Commission the barrier.

3.3 LID REMOVAL
In order to access the mechanical drive shaft and bearing assemblies, and to adjust the limit
switches, it will be necessary to remove the lid of the barrier. This is a simple operation but
should still be approached with care at all times.
In order to remove the lid the door must rst be opened using the keys supplied with the
barrier.
The barrier must now be immediately isolated from the mains electricity supply by turning o
the supply at the isolator as indicated in the drawing.
Underneath the top plate located centrally is a wing nut this must be removed from the
location rod, and carefully stored for later.
The lid can now be removed carefully from the barrier cabinet in an upward direction.
Important note- Ensure that the lid and all xings are safely stored so that damage or loss is
avoided. In severe weather ensure that the lid is removed for very short periods of time or
that the barrier is adequately protected.

Remove wing nut
to allow lid to be
removed.

With the lid removed extreme care should be taken if the barrier is operated with the
mains supply energised. Multiple trapping hazards exist. Any adjustments should only
be carried out by a suitably trained and qualied engineer.

3.4 BEAM ATTACHMENT AND REMOVAL
The beam xing arrangement is shown in Fig 4 (below)
If the beam is being attached during installation, check the length of beam and shorten if
required. Carefully remove any burrs and t the supplied black plastic end cap into the cut
end of the beam.

3.5 ELECTRICAL OPERATING SYSTEM
The electrical control panel is tted inside the barrier cabinet within an IP rated
enclosure.
All control electrical connections are pre-wired at our factory, only mains cable and
external control cables require connecting on site.
The position of the beam is detected in the raised and lowered positions by two limit switches
that are xed to the top plate of the barrier cabinet.
For safety reasons an isolator switch is tted on all barriers this should be turned o before
any work is carried out on the barrier.
