5.3.2
Installing empty ducts
Specifications to be agreed with the person running the site
involved in the installation.
Recommended diameters for empty ducts: at least PG 21.
Observe the laws of the country where the equipment is installed.
5.3.3
Installing the cables
Proceed as described below:
1.
Disconnect the mains in the room where the installation will
be performed by using the main switch and lock it to prevent
it from being turned on.
2.
Cut the cables (leave some margin).
3.
Label both ends of the cable (at about 150-200 mm from the
cable end) with a felt-tip pen or an adhesive strip depending
on the cable definition.
MAXIMUM LENGTH OF TWISTED PAIR CABLE
The Installer Technician must ensure that the actual length of each
cable does not exceed 40 m (the calculation must include vertical,
ceiling, beam and cantilever cables). The cable length has a
significant impact on the quality and performance of the entire
system.
Contact VIDEOMED S.r.l. to find a suitable technical solution.
INSTALLING THE CABLES
Make sure there is enough clearance when installing the cable.
Avoid excessively acute angles, narrowing and bending the cable,
as this could cause a cable failure and a system malfunction.
Overhangs, reinforced walls or intermediate ceilings must be
removed when replacing cables previously installed.
