BOOM BARRIER BV5868 33
WARNINGS AND SAFETY RULES
Make sure the soil is stable and solid enough to ll the foundation. There should be no obstructive
pipes or cables at the site where the foundation pit is dug. The foundation must be laid deeper
than the frost-line depth.
Make sure that there is no risk of ooding in the area where the barrier is installed, otherwise
make the foundation for the barrier 100–200 mm above ground level.
Select foundation materials (concrete, rebars, etc.) in accordance with building regulations and
process requirements. Asolid and stable foundation will ensure reliable and safe operation of
the barrier.
The foundation surface must be at and horizontal.
Ensure that there is sucient space for assembly and operation of the barrier system. The distance
from the barrier cabinet and the boom tip to the nearest stationary obstacle (wall, fence, etc.) must
be at least 500 mm. The space around the barrier should allow easy and safe manual unlocking.
Check that there will be no obstacles to the movement of the barrier boom when opening and
closing (trees, power lines, walls, fences, etc.). The boom movement should occur at adistance
of at least 5mfrom overhead power lines.
The barrier should not block the pedestrian passageways.
Make sure that the barrier and barrier system devices are protected from accidental impact by
passing vehicles. Otherwise, ensure that safeguards (fencing) are in place.
The surfaces of the sites where the barrier system components are installed must be robust
and used as areliable and rigid support. Otherwise, measures should be taken to reinforce the
installation sites.
For boom lengths exceeding 4m, we recommend installing asupport post (optional). The height
of the support post must be adjusted to the height of the boom.
In case of poor visibility of the boom, e.g. in the dark, it is necessary to attach reective stickers
(optional) to the boom.
Permanent control facilities should be located within the barrier’svisibility at aheight of at
least 1.5mand away from moving elements. Control facilities shall not be publicly accessible.
The electrical system must be provided with aprotective earth connection. The section of the
electrical system to which the product is connected must be equipped with ashort-circuit
protection device (circuit breaker or similar device). The distance between the terminals in the
protective switchgear must be at least 3mm.
The cables for control and safety devices should be laid separately from cables with mains voltage.
Protect cables from contact with any rough or sharp surfaces; use corrugated tubes, pipes and
cable ducts to lay the cables. When wiring the barrier system components, use adouble-insu-
lated multicore copper cable.
The parameters of the electric cables used (section, number of wires, length, etc.) should comply
with the wiring diagram, device power, laying distance, laying method and ambient conditions.
Check and, if necessary, adjust the barrier for safe operation (EN 12453), as incorrect adjustment
may pose ahazard. Proper and safe adjustment is carried out by trained and qualied specialists
from acompetent organization.
During operation, protection against squeezing, impact, trapping, dragging and other hazards
(EN 12453, EN 12604) must be ensured by installing safety devices, safeguards, and observing
safe distances and clearances.
When operating outside the barrier visibility area or when automatic barrier closing is activated
in the settings, photocells (or equivalent safety device) must be installed.
