Stretch the cable 8 through the corrugated tube 7. The installation of the corrugated tube is
obligatory.
8.2.6.
Install junction boxes and power supply units (if according to the project PSU are installed
within the perimeter).
If you use junction boxes «JB-30» and power supply units «PSU-U-24-0,7», install them on
the supports together with the sensor units inside the protected perimeter. To connect the
cable 8, protected with the corrugated pipe 7, with the JB (or PSU), one should remove one of
the threaded cable connections PG9 and place the bushing 14 with the corrugated pipe 7 into
the hole. It is recommended to use one «PSU-U-24-0,7» for power supply of two contiguous
sensors. It should be remembered that there are five free terminal blocks in «PSU-U-24-0,7»
(«1» - «5»). That is why, it is not necessary to install a junction box on the support with this
power supply unit. Mounting elements are supplied with the delivery set of «JB-30» and
«PSU-U-24-0,7».
ATTENTION! To reduce the level of electromagnetic interferences, it is recommended
to mount the power supply unit at a distance up to 300 m from the place where the
sensors are installed.
