7 SAFETY MEASURES
7.1 “Rules of technical operation of consumers’ electrical facilities” and “Rules of safety of
consumers’ electrical facilities” should be observed while installation and repair of the system.
7.2 Technicians are allowed to install, maintain and repair the system after they learn special
instructions and pass exam related to safety measures during the work with electrical equipment up to
1000 V voltage.
7.3 Maximum value of average flux of SHF energy at the distance 1 m from the system transmitter
does not exceed 1mcW/cm
2
, that meets safety regulations for technicians who do not work with SHF.
7.4 Power supply of the charger is carried out from 220 V mains. Before one starts working it is
necessary to read the charger description and rules specified in sections 5.3, 6.5 and 10.2. Safety device
must be replaced only when the charger is OFF the 220V mains.
8 MOUNTING
8.1 Requirements to the Sector Landform and Application Conditions
Surface landform where the system sector is mounted must meet the following requirements:
a)
maximum height of the sector surface irregularities is +0,3m, height difference within the sector
is 3 m maximum;
b)
in the sector there must not be moving gate wings, bushes, trees and etc. at the distance of 4m
from the axis connecting Tx and Rx. There can be single immovable objects which do not prevent
direct vision between Tx and Rx; single trees and bushes with sparse leaves;
c)
maximum height of grass must be 0,3m;
d)
maximum height of snow must be 0,5m;
e)
along the sector axis there must not be fences, walls and other objects at the distance less than
20m;
f)
if Tx and Rx are covered with ice the system operation can be unstable (false alarms and etc.);
g)
transport circulation at the distance less than 20m from the sector axis is prohibited.
8.1.1 Additional recommendations on the system sector arrangement:
1)
if the grass height is less than 0,5 m the maximum sector length is 35 m, if the grass height is less
than 0,7 m the maximum sector length is 12-20 m.
2)
if there are surface irregularities more than 0,3 m or height difference more than 3m it is
recommended to reduce the sector length to 40m and less (depending on the landform).
3)
if there are extended vertical surfaces (wall, fence, a group of trees or bushes) located along the
sector axis, recommended length of these sectors is 20-25m maximum.
4)
if sectors are located at the distance less than 20 m along the route where heavy hauler can
circulate, the sector length should be reduced up to 20-25m.
